Discovery
The issue of the activity of nuclei of galaxies (AGN) was first raised by Soviet-Armenian physicist Prof. Victor Ambartsumian in the early 1950s. Although the idea concerning the activity of galactic nuclei for the first time was accepted very skeptically, after many years, as a result of the pressure of observations (the discovery of quasars, radio outbursts of galaxies, consequences of explosions in nuclei, ejection from nuclei, etc.) it did gain recognition. The concept of AGN now is widely accepted.
