Scientific paper

Many quasar-like objects show evidence for massive binary black holes. The recent discovery of a massive (5×106M_sun;) object in the centre of the local group dwarf elliptical M32 greatly raises the probability of forming such binaries through galactic mergers. The author argues that the enhancement of all kinds of activity (quasar-like activity and star formation) in galaxies with companions is not so much a consequence of tidal interaction between the massive galaxies as the result of collisions with their dwarf satellites.
