Spitzer/IRS Mapping of Local Luminous Infrared Galaxies
Miguel Pereira-Santaella, Almudena Alonso-Herrero, George H. Rieke +1
We present results of our program Spitzer/IRS Mapping of local Luminous Infrared Galaxies (LIRGs). The maps cover the central 20"x20" or 30"x 30" regions of the galaxies, and use a…
On the Infrared Properties of Dusty Torus
L. Videla, P. Lira, A. Alonso-Herrero +2
We performed imaging on 49 type 2 Seyfert galaxies in 6 near- and mid-infrared bands (1-10m). We are separating the contribution of the torus from the host galaxy by radial prof…
The mid-infrared emission of local Luminous Infrared Galaxies
Almudena Alonso-Herrero
In this paper we use the complementary imaging capabilities of Spitzer (sensitivity) and Gemini-South/T-ReCS (spatial resolution) to study the mid-IR properties of local (d < 75Mpc…
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…
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…
