Thanks, Don. Although perhaps gravitational lensing techniques would have detected them also, I wonder about black holes in mass-poor regions- those with no accretion disks, and thus no emmisions (other than gravity waves). Or perhaps "small" black holes, those unrelated to stellar evolution? Surely we haven't inventoried all possible large forms of baryonic matter. --- "Don J. Colton" <djcolton@piol.com> wrote:

He discussed brown dwarfs etc. as a possibility but said numerous surveys using gravitation lensing etc. had failed to convince anyone this was a significant component. He didn't talk about the other possibilities but we ran out of time for questions.
