The team looked at the quasar HE0450-2958 from Chile and noticed that a jet of matter from the black hole pointed exactly in the direction of a star forming region in a nearby galaxy. As Louise would ask: if galaxies are formed this way, even early in cosmic time, then where did all the black holes come from? New Scientist calls this the 64000 dollar question. Goodbye LCDM.
Note that this is a neat opposite of the Arp theory, where galaxies eject quasars. It would explain why the local galaxy M33 is missing its central black hole: the black hole has not yet arrived in the centre. That is, the black holes can create galaxies from nearby gas clouds and only later migrate into the galactic centres. The quasar jets can contain so much matter that they might create a whole galaxy out of nowhere!
