3D fun.

NGC 6769-6770-6771 form this superb triple system in the southern constellation of Pavo. It is also known as the Devil's Mask. The trio are 190 million light years away, and receding. Both NGC 6769 and NGC 6770 are receding at similar velocities of about 3800 km/s - a redshift just over 0.01, while NGC 6771 is receding at a slightly higher rate of 4200 km/s.

 

The central bulge in all three galaxies are of similar brightness. NGC 6771 has an interesting boxy shape which is indeed a rare occurrence among galaxies. It is unusual in that it has two comparatively straight dark lanes and a fainter arc that curves towards the third galaxy

 

Both NGC 6769 and NGC 6770 are spiral galaxies, yet very different. NGC 6769 has very tightly wound spiral arms, while NGC 6770 has two major spiral arms, one of which is fairly straight pointing towards the outer disc of NGC 6769. The blueish colour of the spiral arms indicate the presence of many star forming regions.

Thanks for looking

 

A couple of entwined galaxies proceeding with their mergence. The two tails appear to wrap all the way around the left side of the galaxies and connect back where that background spiral appears at the bottom of the image. They'd be off the left and bottom sides of the frame if you could see them, but the exposure wasn't quite long enough to capture such faint features.

 

This is part of a snapshot / gap filler program for Julianne Dalcanton involving the study of peculiar galaxies which HST had never observed before. Only one filter is available for each, so color must come from elsewhere. In this case, I used the PanSTARRS survey to quickly add some color. You can see that many of the fine details in the image are lacking distinctive colors due to the lower resolution of the color data.

 

All of the observations from this proposal are available immediately to the public, so it can be fun to poke around. In fact HST took this image only a few hours before I made this image, and less than 24 hours before I posted it here.

These are the most distant galaxies from us (at about 12 million light years) that do not show redshift. The expansion of space, or Hubble flow, kicks in at about that distance for all galaxies. M81 (on the left) is gravitationally disturbing M82 (on the right). These tidal interactions have increased the star formation rate in M82, and we can see hydrogen streaming out of the center of that galaxy in response to the rapid star formation.

 

I've shot this pair from Joshua Tree and Death Valley, and probably a few other places. The RGB data is from 47 sub frames of various exposures lengths, but generally good quality. The Atik 314L+ color CCD in combination with the Hyperstar has done well there. But now I can add Hα from my driveway, so I did. An additional 15 5 min exposures with the Atik 414-EX and hydrogen alpha filter. Thank you to Light Vortex Astronomy for providing instructions on how to combine the data.

An interesting interaction which resulted in some rather long tidal streams outstretched from a spiral galaxy like arms. I'm not sure they could be considered as part of the arms or just streams.

 

I used Dark Energy Survey DR1 for color. Not quite sure on the filters for that. Will have to update the description when I figure it out, but it looks like a typical combination of near-infrared / red / green filters. I took the image straight off legacysurvey.org's viewer since I'm having trouble getting data access. Seems my email isn't working tonight.

 

If you take a look at the DES DR1 data in the legacysurvey viewer you can see there is a transient of some type near the center of the spiral galaxy. Could be a supernova, or it could just be a sneaky asteroid. It's hard to tell without a date/time for the observation that captured the transient, though.

This 2004 composite image shows views of the galaxy cluster MACSJ1423, using optical and X-ray telescopes. The optical image, a 3-color composite from the Subaru prime focus camera, shows white and blue galaxies centered around a large elliptical galaxy. The Chandra X-ray image shows hot gas displayed in red. The mass of the hot gas is about 6 times greater than the mass of all the billions of stars in all of the galaxies in the cluster. This galaxy cluster have a redshift of 0.54, at a distance corresponding to a light travel time of 5.4 billion years.

Revisiting our old friend IC 5063, this time with a bit of color, clearly revealing the emission line features emerging nearly perpendicular from the crepuscular rays. These features, in cyan, are most easily viewed zoomed in on the nucleus. They are thought to be formed by the actively accreting supermassive black hole in the center of the galaxy. In this case, the black hole may have a dark "donut" of dust around its equatorial axis, and the extremely bright light creates ionizing cones and jets of material out of the polar axis.

 

The processing here is not only extreme, but also a combination of data from two separate HST snapshot proposals, and the wondrous Legacy Survey DR9 release. I used my hacky Photoshop subtraction model to clearly reveal the center of the galaxy in the Hubble data, while the outer parts are partially filled using the LS DR9 imagery, more smoothly and confidently illustrating the galaxy's outer tidal structures.

 

Hubble image coverage is incomplete; some sections contain only one filter/color.

Been on flickr for 6 years and seen and admired, learnt from and been influenced by so many wonderful and talented photographers/artists in that time. I've become friends with quite a few. We've written, shared stuff about, not only photography, but also about how things were going in each of our lives. Four, in particular, have taught me a valuable lesson. And that's to look at the small things. The detail I wouldn't, in pursuit of my own thing, have noticed. The final one, Fran, gives me a whole lot more. Most of all is her patience with my photography obsession. I'd need to write a book about her and, fortunately for anybody reading this, I've no intention to go for a ramble down that particular road.

 

In no particular order they're :

www.flickr.com/photos/41066614@N05/ whose uniquely magical portrayals of the minutest details of the natural world continue to astonish and astound with their beauty.

 

www.flickr.com/photos/152305124@N02/ Brandon consistently finds and presents the beauty in the ordinary in his home town in Idaho. He's been doing it for years and I don't know how he continues. He has to know every building and every crack in every pavement of Pocatello. But it's there for everybody on flickr to look at and enjoy. Look out too for the gorgeous, tangentially rambling essays he sometimes adds to his images.

 

www.flickr.com/photos/dainj/ Redshift Rider, again, finds beauty in both the organic and man-made. His stuff and how he presents it, like others mentioned here, pushes the edges of his and the viewer's perception of the world.

 

www.flickr.com/photos/26729396@N00/ Peter's photos of flowers, in particular, blow me away every time. He uses old lenses, adapted for a digital camera, that capture the hearts of each of his subjects. He doesn't over-process them with any software apart from a raw converter. Neither does he add them to many flickr groups; so their audience is nowhere big enough for them to receive the attention and admiration they deserve.

 

I hope my descriptions of each of above (a) does them justice, and (b) doesn't cause them embarrassment.

The pic. above is my particular twist on everything I've written.

 

M106 (NGC 4258) est une galaxie spirale intermédiaire située dans la constellation des Chiens de chasse à 23,5 ± 1,0 millions d'années-lumière. M106 a été découvert par l'astronome français Pierre Méchain en 1781. Apparemment, Charles Messier n'a ni observé ni enregistré cette galaxie dans son catalogue. C'est l'astronome américano-canadienne Helen Sawyer Hogg qui a ajouté NGC 3379, NGC 4258 et l'amas globulaire NGC 6171 au catalogue Messier sous les désignations M105, M106 et M107.

 

NGC 4258 a été utilisé par Gérard de Vaucouleurs comme une galaxie de type morphologique (R')SAB(rs)b dans son atlas des galaxies.

 

La classe de luminosité de M106 est II-III et elle présente une large raie HI ainsi qu'un jet d'ondes radio. De plus, c'est une galaxie LINER, c'est-à-dire une galaxie dont le noyau présente un spectre d'émission caractérisé par de larges raies d'atomes faiblement ionisés. Enfin, M106 est une galaxie active de type Seyfert.

 

Près d'une centaine de mesures non basées sur le décalage vers le rouge (redshift) donnent une distance de 7,271 ± 0,980 Mpc (23,7 ± 3,2 millions d'années-lumière), ce qui est semblable et à l'intérieur des distances calculées en employant la valeur du décalage (6,26 ±0,47 Mpc). Il existe cependant une mesure encore plus précise de sa distance, soit 7,2 ± 0,3 Mpc, grâce à la présence d'un mégamaser à vapeur d'eau dans la galaxie.

Dotted across the sky in the constellation of Pictor (The Painter’s Easel) is the galaxy cluster highlighted here by the NASA/ESA Hubble Space Telescope: SPT-CL J0615-5746, or SPT0615 for short. First discovered by the South Pole Telescope less than a decade ago, SPT0615 is exceptional among the myriad clusters so far catalogued in our map of the Universe — it is the highest-redshift cluster for which a full, strong lens model is published.

 

SPT0615 is a massive cluster of galaxies, one of the farthest observed to cause gravitational lensing. Gravitational lensing occurs when light from a background object is deflected around mass between the object and the observer. Among the identified background objects, there is SPT0615-JD, a galaxy that is thought to have emerged just 500 million years after the Big Bang. This puts it among the very earliest structures to form in the Universe. It is also the farthest galaxy ever imaged by means of gravitational lensing.

 

Just as ancient paintings can tell us about the period of history in which they were painted, so too can ancient galaxies tell us about the era of the Universe in which they existed. To learn about cosmological history, astronomers explore the most distant reaches of the Universe, probing ever further out into the cosmos. The light from distant objects travels to us from so far away that it takes an immensely long time to reach us, meaning that it carries information from the past — information about the time at which it was emitted.

 

By studying such distant objects, astronomers are continuing to fill the gaps in our picture of what the very early Universe looked like, and uncover more about how it evolved into its current state.

Abell 2199 is a galaxy cluster in the Abell catalogue featuring bright cluster-galaxy NGC 6166, in the center of the image. NGC 6166 appears to be a quadruple galaxy with four cores. The four objects however appear to have very different redshifts so they may in fact just be superimposed galaxies. Modelling suggests that there are two elliptical galaxies here and one of them appears to have caused a wake as it passes through the outer envelope of NGC 6166. Abell 2199 is part of the great wall of galaxies whose other prominent clusters are the Coma Cluster (Abell 1656), The Leo cluster (Abell 1367) and the Hercules cluster (Abell 2151). The cluster contains at least 88 and probably of the order of 200 galaxies. However on the full FOV image it is clear that there are a lot more galaxies visible. Not sure what will take the least effort: counting the stars or counting the galaxies.

Preparation activities are on-going in Turin, at Thales Alenia Space for the installation of the thermal protection layers on the payload and service module of ESA Euclid's spacecraft.

 

Euclid is an ESA mission to map the geometry of the Universe and better understand the mysterious dark matter and dark energy, which make up most of the energy budget of the cosmos. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion of the Universe.

Messier 106, also known as NGC 4258, is an intermediate spiral galaxy located in the constellation Canes Venatici. It lies at a distance of roughly 23 million lightyears and spans some 135.000 ly in diameter.

What makes M106 interesting for our cooperative efforts in the DSC are its outflows around the galaxy’s core, caused by the active supermassive black hole at the galaxy's center. This black hole is actively accreting material, which leads to the production of powerful jets, called AGN jets, which in turn give rise to the observed outflows (AGN = Active galaxy nuclei). Note that the outflows in M106 are called “anomalous arms”, but will be referred to as “outflows” in the following text.

Another interesting feature in our frame are the many background galaxies with various interesting attributes that we’ll dive into later in the write-up.

The jets and associated outflows in M106 have been studied extensively to better understand the processes involved.

 

As our goal in the DSC is to provide scientifically valuable data, we focused on gathering Hydrogen alpha (Ha) as well as Oxygen III ([OIII]) for the outflows as this allows for a wider array of observations and insight. A full description and breakdown of our observations, paired with professional data will be given in the next section.

 

In order to reveal the outflows in full detail as well as ensure nice details in the galaxy and background, our goal was primarily set on Ha, [OIII] and Lum data.

With the small FOV group of the DSC we started gathering data in February and imaged for a total of 3 months, followed by 2 months of pre- and post-processing the data. Being back with a nearly full team, we had a total of 18 people working on the project - 1 Editor, 1 Stacker and 1 supervisor as well as 15 photographers- in the end we managed to get a total of 566h02m of integration - the longest ever on this galaxy. Note that 226h06m of that total is Ha, 80h30m is [OIII] and 141h24m is Lum, meeting our goals!

  

Before getting into any details in the picture, I want to thank everybody who contributed to this project. As always, it was a pleasure working together with everybody!

Interesting features in our image

  

- M106’s outflows - Anomalous spiral arms

 

As noted in the introductory text to this project, a main focus for the DSC was revealing M106’s outflows in great detail.

 

These outflows, or anomalous spiral arms are jet-driven outflows and so form as a direct consequence of the active galaxy nuclei in M106. Our amateur efforts focused on gathering both Ha and [OIII] in order to showcase the distribution of intensity of emission. While it is very common to include Ha in the data-split when capturing M106, [OIII] is rather rarely seen which made it even more interesting. In the end we managed to gather over 220h of Ha and over 80h of [OIII] data.

In order to ensure that the signal picked up is the isolated emission line of interest, we applied continuum subtraction (as we always do) and confirmed the presence of [OIII] in the streams. It can be seen that the [OIII] emission is much weaker than the Ha, which was expected. A direct comparison between Ha and [OIII] can be found below. Note that the [OIII] is mainly found in the east part of the galaxy.

While our image provides a deep, detailed look at the spiral arms, it is limited to only optical emission lines. However, M106’s outflows not only emit in optical wavelengths, but also in Radio, X-ray, UV,...

 

So in order to tell the full story one needs to consider other wavelengths too, which lead us to combining our data with professional datasets of M106 that cover X-Ray -, radio - and IR emissions. For this, we used Chandra’s X-ray imagery, VLT’s radio coverage and Spitzer’s IR data. In a final, comprehensive image of M106 we mapped X-ray to purple, radio to yellow and IR to red (mixed in with Ha). The full resolution of this revision of the image can be found under astrobin’s revision D or on our website: deepskycollective.com/m106/multiwave

- Small galaxies and their features

 

Other features to draw attention to are the numerous, interesting small galaxies in the frame, some of which have major outflows that can be clearly seen in our image thanks to the deep Broadband observation, using over 250h of broadband data.

Three of those galaxies are shown below - all of these are AGN galaxies with huge outflows (note that NGC 4226’s is larger than the galaxy itself).

- Background galaxies

 

As our image is of unprecedented depth, many more background galaxies have been revealed, most of which lie at tens of- if not hundreds of million of lightyears. As we overall used relatively big telescopes for the project, not only do we have immense depth, but also detail. We encourage everyone to go check out our full resolution image on our website so you can zoom in and explore the image yourself.

Besides the big NGC 4217 on the right hand side of the frame, the team’s favourite definitely is NGC 4231 and 4232 - a pair of galaxies that is merging and can be seen in the top of the screen. Looking spectacular, these galaxies lie at a distance of over 350 million lightyears and reflect what our milky way and M31 will go through in a few billion years. Lacking observations from big space telescopes, our image might be the clearest of the galaxy pair yet.

- Depth of image

 

An interesting measure of how “deep” an image is, is to check the limiting magnitude - this measure tells you down to what magnitude you can capture (i.e. what the faintest thing picked up is). As we had lots of Broadband data we figured this would be an interesting measure to have and compare to later projects. It turned out that our limiting magnitude is 23.3 from an unprocessed stack and 24.0 when applying Deep SNR. Comparing this with values from big professional telescopes we’re only off by roughly one magnitude which was encouraging to see.

Given the depth we wanted to check what the most distant objects picked up are… Massive thank you to Steve Mandel who took care of this! Below our raw annotated stack can be found. The three annotations are the three furthest objects in the image, with the most distant being a staggering 11.7 billion lightyears away from us!

Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today.

 

The tiny galaxies were discovered by Wold and his Goddard colleagues, Sangeeta Malhotra and James Rhoads, by sifting through Webb images captured as part of the UNCOVER (Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization) observing program, led by Rachel Bezanson at the University of Pittsburgh in Pennsylvania.

 

For much of its first billion years, the universe was immersed in a fog of neutral hydrogen gas. Today, this gas is ionized — stripped of its electrons. Astronomers, who refer to this transformation as reionization, have long wondered which types of objects were most responsible: big galaxies, small galaxies, or supermassive black holes in active galaxies. As one of its main goals, NASA’s Webb was specifically designed to address key questions about this major transition in the history of the universe.

 

Recent studies have shown that small galaxies undergoing vigorous star formation could have played an outsized role. Such galaxies are rare today, making up only about 1% of those around us. But they were abundant when the universe was about 800 million years old, an epoch astronomers refer to as redshift 7, when reionization was well underway.

 

In this image, white diamonds show the locations of 20 of the 83 young, low-mass, starburst galaxies found in infrared images of the giant galaxy cluster Abell 2744. This composite incorporates images taken through three NIRCam filters (F200W as blue, F410M as green, and F444W as red). The F410M filter is highly sensitive to light emitted by doubly ionized oxygen — oxygen atoms that have been stripped of two electrons — at a time when reionization was well underway. Emitted as green light, the glow was stretched into the infrared as it traversed the expanding universe over billions of years. The cluster’s mass acts as a natural magnifying glass, allowing astronomers to see these tiny galaxies as they were when the universe was about 800 million years old.

Not the other night, but a flashback to a wonderful evening about four years ago. This was taken during an epic 20-minute fireworks display arranged for us in the woods next to a former manager's home, celebrating his retirement from the company back in 2010.

 

Best retirement party ever. It's just a shame it was for one of the few decent managers with have left.

I'm sure there are two galaxies doing something here, I'm just not entirely sure what went on in the past billion or so years to get a big, fluffy line of stars, gas, and dust all stretched out like that.

A spiral galaxy, an edge-on disk, a few other background goodies, and a remarkable pair of dwarf galaxies. The bright pair near the right side of the frame could be an interacting pair, or, interestingly perhaps an overlapping line-of-sight pair, though I really have no way of confirming that. Pay close attention to the reddish/yellowish dust around that bright nucleus at the bottom. See how it encircles the nucleus without looking all that disturbed? Maybe they aren't interacting. Or maybe if they are, it's at an early point. Either way, it's very interesting to see backlit dust in the outskirts of a galaxy. It's usually invisible to us at these wavelengths.

 

Color comes from PanSTARRS this time.
