Pretty boring, evidently:

Quasars: Cosmic Powerhouses Dwelling In Humble Homes (http://www.sciencedaily.com/releases/2004/05/040526065614.htm)


Quasars, the most brilliant of cosmic fireworks, appear to shine forth from humdrum galaxies in the early universe, not the giant or disrupted ones astronomers expected.

"It's like finding a Formula One racing car in a suburban garage," said Dr Scott Croom of the Anglo-Australian Observatory in Australia who led the study.

The science paper can be found here (http://xxx.lanl.gov/abs/astro-ph/0401442). It's too bad that they didn't get more actual detections (mostly, they have just upper limits to the galaxy's luminosity). I am not sure that "humble" is necessarily on the mark. They're just not the monster galaxies some might have expected (at least in this sample). 2L* and 3L* galaxies are still significantly more luminous than the MW.

Actually I was at the conference in Vancouver last week where that paper was discussed and they do have plans to do more observations. If this trend holds up, it may yet prove another interesting link in explaining quasars and their environs.
