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…
Reduction Algorithms for the Multiband Imaging Photometer for Spitzer: 6 Months of Flight Data
K. D. Gordon, G. H. Rieke, C. W. Engelbracht +27
The first six months of flight data from the Multiband Imaging Photometer for Spitzer (MIPS) were used to test MIPS reduction algorithms based on extensive preflight laboratory dat…
24 micron Properties of X-ray Selected AGN
J. R. Rigby, G. H. Rieke, R. Maiolino +13
We examine the 24 micron to X-ray color of 157 X-ray--selected AGN as a function of X-ray obscuration and optical classification in the Chandra Deep Field South. The sample consist…
Massive star formation in Luminous Infrared Galaxies
A. Alonso-Herrero, G. H. Rieke, M. J. Rieke +1
We present HST/NICMOS observations of a sample of LIRGs. We show that active star formation appears to be occurring not only in the bright nuclei of these galaxies, but also in lum…
An Infrared View of Local Universe AGN
Almudena Alonso-Herrero
We summarize recent results on the infrared (IR) nuclear properties of Seyfert galaxies. 100% of all Seyfert 1-1.9$ and ~50% of all Seyfert 2s in the CfA and RSA samples observed w…
Star Formation Rate estimators: [OII]3727 vs. Halpha for local star-forming galaxies
A. Aragon-Salamanca, A. Alonso-Herrero, J. Gallego +4
The [OII]3727 emission line is frequently used as an indicator of the star formation rate (SFR) despite its complex dependence on metallicity and excitation conditions. We have ana…
