Detecting Obscured AGN in the Distant Universe with Spitzer
J. L. Donley, G. H. Rieke, P. G. Perez-Gonzalez +2
We present the results of a Spitzer search for obscured AGN in the Chandra Deep Field-North, using both radio-excess and mid-infrared power-law selection. AGN selected via the form…
The quest for obscured AGN at cosmological distances: Infrared Power-Law Galaxies
Almudena Alonso-Herrero, Jennifer L. Donley, George H. Rieke +2
We summarize multiwavelength properties of a sample of galaxies in the CDF-N and CDF-S whose Spectral Energy Distributions (SEDs) exhibit the characteristic power-law behavior expe…
Strong dusty bursts of star formation in galaxies falling into the cluster RXJ0152.7-1357
D. Marcillac, J. Rigby, G. Rieke +1
We have observed the cluster RX J0152.7-1357 (z0.83) at 24m with the Multiband Imaging Photometer for Spitzer (MIPS). We detected twenty-two sources associated with spectr…
Spitzer Massive Lensing Cluster Survey
E. Egami, G. H. Rieke, J. R. Rigby +9
We are currently undertaking a Spitzer GTO program to image ~30 massive lensing clusters at moderate redshift with both IRAC and MIPS. By taking advantage of the gravitatinoal lens…
