My only research today was attendance at a nice blackboard talk by Renbin Yan (NYU) on the origin of LINER emission in galaxies. He has kinematic evidence that it is produced by evolved stars rather than nuclear emission from an accreting black hole. If he is right—and I think he is—this will make some waves in the galaxy evolution world, where LINER ratios has been assumed to mean black hole.
It is making waves already. e.g. http://adsabs.harvard.edu/abs/2010MNRAS.402.2187S
