Observations of a 'homeless' quasar suggest new ideas for galaxy formation
A homeless black hole might be building a new galaxy to live in, new observations suggest.
The find could be the latest clue in a longstanding mystery in astronomy: whether supermassive black holes or the galaxies that house them form first.
“If it is true, it is very surprising, as it gives a whole new role to the black holes in the universe — not as devourers but as creators of galaxies,” comments Padelis Papadopoulos of the University of Bonn in Germany.
