Your galaxy of origin is Andromeda.
Andromeda, also known as Messier 31 (M31), is a spiral galaxy located about 2.5 million light-years away. It is thought that the Milky Way and Andromeda will collide several billion years from now. The black holes located in both galaxies will then reside in the large, elliptical galaxy that results from this merger.
These results are available online and will be published in the June 20th issue of The Astrophysical Journal. Many of the Andromeda observations were made within Chandra’s Guaranteed Time Observer program.
