An Initial Look at the FIR-Radio Correlation within M51a using Spitzer

Eric J. Murphy, Lee Armus, George Helou +2

We present an initial look at the FIR-radio correlation within the star-forming disk of M51a using {\it Spitzer} MIPS imaging, observed as part of the {\it Spitzer} Infrared Nearby…

Mid-infrared selection of quasar-2s in Spitzer's First Look Survey

M. Lacy, G. Canalizo, S. Rawlings +6

We present early results from the spectroscopic follow-up of a sample of candidate obscured AGN selected in the mid-infrared from the Spitzer First Look Survey. Our selection allow…

Fire and Ice: IRS Mid-IR Spectroscopy of IRAS F00183--7111

H. W. W. Spoon, L. Armus, J. Cami +8

We report the detection of strong absorption and weak emission features in the 4--27 micron Spitzer-IRS spectrum of the distant ultraluminous infrared galaxy (ULIRG) IRAS F00183--7…

Photometric Calibrations for the SIRTF Infrared Spectrograph

P. W. Morris, V. Charmandaris, T. Herter +3

The SIRTF InfraRed Spectrograph (IRS) is faced with many of the same calibration challenges that were experienced in the ISO SWS calibration program, owing to similar wavelength co…

The Nature of the Compact/Symmetric Near-IR Continuum Source in 4C 40.36

E. Egami, L. Armus, G. Neugebauer +3

Using NICMOS on HST, we have imaged the emission-line nebulae and the line-free continuum in 4C 40.36, a ultra-steep spectrum FR II radio galaxy at z=2.269. The line-free continuum…

High Resolution WFPC2 Imaging of IRAS 09104+4109

L. Armus, B. T. Soifer, G. Neugebauer

With a infrared luminosity of nearly 10^13 Lsuns, IRAS 09104+4109 is the most luminous galaxy with z<0.5 in the IRAS All Sky Survey. A radio-loud Seyfert 2 type optical spectrum, a…
