Sombrero Galaxy

(M104, NGC 4594, Messier 104)
(striking spiral galaxy with very large bulge)

The Sombrero Galaxy (M104 or Messier 104 or NGC 4594) is a spiral galaxy about 31 million light-years' distant that has a large central bulge. It is very bright and has a very massive central supermassive black hole (SMBH). It has been of recent interest because it shows characteristics that suggest it might produce nanohertz gravitational waves.
