Pegasus V ultra-faint dwarf galaxy

Pegasus V (Andromeda XXXIV) is a new ultra-faint satellite galaxy of Andromeda (M31) and is one of the furthest away as it is about 242 kpc (780,000 light years) from its nucleus. However, it is slightly closer to our Milky Way, in fact it is 692 kpc (about 2.25 million light years) away. The diameter is about 600 light years.

 

It was studied by the same international group that characterized Pisces VII (Michelle L. M. Collins, Emily J. E. Charles, David Martinez Delgado, Matteo Monelli, Noushin Karim, Giuseppe Donatiello, Erik J . Tollerud, Walter Boschin) and the results were illustrated in a paper with first author Dr. Collins of the University of Surrey.

 

I discovered PegV during a specific search for new M31 satellites on January 22, 2021 in the DESI LIS data. It is now my sixth galaxy discovered and the second in the Local Group.
