Scientific paper

Observational data supporting the existence of black holes are presented graphically and characterized in a general review. Object classes discussed include quasars as galaxy cores, X-ray-emitting binaries (Cyg X-1, LMC X-3, and the apparent miniature quasar SS 433), radio galaxies and quasars with twin jets, and interacting galaxies. This evidence is found to strongly suggest that quasars are accreting black holes of mass about 10 to the 8th solar mass, that they formed more easily in earlier stages of the universe (corresponding to redshifts around 2), and that they are analogous in many ways to the stellar-mass object SS 433.
