Groups of Galaxies at Intermediate Redshift (2009)
Miller, Eric D., Bautz, Marshall, Grant, Catherine, Hickox, Ryan, Brodwin, Mark, Murray, Stephen, ...
Galaxy groups are key tracers of galaxy evolution, cluster evolution, and structure formation, yet they are difficult to study at even moderate redshift. We have undertaken a project to observe a...
Active Galactic Nuclei and the Truncation of Star Formation in K+A Galaxies (2009)
Brown, Michael J. I., Moustakas, John, Caldwell, Nelson, Palamara, David, Cool, Richard J., Dey, Arjun, ...
We have searched for active galactic nuclei (AGNs) in K+A galaxies, using multiwavelength imaging and spectroscopy in the Bootes field of the NOAO Deep Wide-Field Survey. The K+A galaxies, which have...
Are Most Low-Luminosity AGN Really Obscured? (2009)
Hopkins, Philip F., Hickox, Ryan, Quataert, Eliot, Hernquist, Lars
At low Eddington ratio (mdot), two effects make it harder to detect AGN given some selection criteria. First, they may transition to a radiatively inefficient state, changing SED shape and...
