A correlation between star formation rate and average black hole accretion in star forming galaxies
Chien-Ting J. Chen, Ryan C. Hickox, Stacey Alberts +14
We present a measurement of the average supermassive black hole accretion rate (BHAR) as a function of star formation rate (SFR) for galaxies in the redshift range 0.25<z<0.8. We s…
Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC). I. Overview
Karl D. Gordon, Margaret Meixner, Marilyn Meade +57
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc). This m…
The Spitzer discovery of a galaxy with infrared emission solely due to AGN activity
S. Hony, F. Kemper, Paul M. Woods +14
We present a galaxy (SAGE1CJ053634.78-722658.5) at a redshift of 0.14 of which the IR is entirely dominated by emission associated with the AGN. We present the 5-37 um Spitzer/IRS…
Broad-Line Reverberation in the Kepler-Field Seyfert Galaxy Zw 229-015
A. J. Barth, M. L. Nguyen, M. A. Malkan +45
The Seyfert 1 galaxy Zw 229-015 is among the brightest active galaxies being monitored by the Kepler mission. In order to determine the black hole mass in Zw 229-015 from H-beta re…
Mid-Infrared Variability from the Spitzer Deep, Wide-Field Survey
Szymon Kozlowski, Christopher S. Kochanek, Daniel Stern +30
We use the multi-epoch, mid-infrared Spitzer Deep, Wide-Field Survey to investigate the variability of 474,179 objects in 8.1 deg^2 of the NDWFS Bootes field. We perform a Differen…
The IRAC Dark Field; Far- Infrared to X-ray Data
J. E. Krick, J. A. Surace, D. Thompson +7
We present 20 band photometry from the far-IR to X-ray in the Spitzer IRAC dark field. The bias for the near-IR camera on Spitzer is calibrated by observing a ~20 arcminute diamete…
The Spitzer Deep, Wide-Field Survey
M. L. N. Ashby, D. Stern, M. Brodwin +30
The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey of ten square degrees in the Bootes field of the NOAO Deep Wide-Field Survey using the IRAC instrument o…
Spitzer observations of a gravitationally lensed quasar, QSO 2237+0305
Eric Agol, Stephanie Gogarten, Varoujan Gorjian +1
The four-image gravitationally lensed quasar QSO 2237+0305 is microlensed by stars in the lens galaxy. The amplitude of microlensing variability can be used to infer the relative s…
