Balancing the Energy Budget between Star-Formation and AGN in High Redshift Infrared Luminous Galaxies
E. J. Murphy, R. -R. Chary, D. M. Alexander +5
(abridged) We present deep Spitzer mid-infrared spectroscopy, along with 16, 24, 70, and 850um photometry, for 22 galaxies located in GOODS-N. The sample spans a redshift range of…
The Chandra Deep Protocluster Survey: Evidence for an Enhancement in the AGN Activity in the SSA22 Protocluster at z = 3.09
B. D. Lehmer, D. M. Alexander, J. E. Geach +8
We present results from a new ultra-deep 400 ks Chandra observation of the SSA22 protocluster at z = 3.09. We have studied the X-ray properties of 234 z ~ 3 Lyman break galaxies (L…
Tracing the Mass-Dependent Star Formation History of Late-Type Galaxies using X-ray Emission: Results from the Chandra Deep Fields
B. D. Lehmer, W. N. Brandt, D. M. Alexander +11
We report on the X-ray evolution over the last ~9 Gyr of cosmic history (i.e., since z = 1.4) of late-type galaxy populations in the Chandra Deep Field-North and Extended Chandra D…
The Evolution of AGN Host Galaxies: From Blue to Red and the Influence of Large-Scale Structures
J. D. Silverman, V. Mainieri, B. D. Lehmer +14
We present an analysis of 109 moderate-luminosity (41.9 < Log L{0.5-8.0 keV} < 43.7) AGN in the Extended Chandra Deep Field-South survey, which is drawn from 5,549 galaxies from th…
Uncovering the Near-IR Dwarf Galaxy Population of the Coma Cluster with Spitzer IRAC
L. P. Jenkins, A. E. Hornschemeier, B. Mobasher +2
We present the first results of a Spitzer IRAC (Infrared Array Camera) wide-field survey of the Coma cluster. The observations cover two fields of different galaxy densities; the f…
Multiwavelength study of massive galaxies at z~2. II. Widespread Compton thick AGN and the concurrent growth of black holes and bulges
E. Daddi, D. M. Alexander, M. Dickinson +16
Approximately 20-30% of 1.4<z<2.5 galaxies with K<22 (Vega) detected with Spitzer MIPS at 24um show excess mid-IR emission relative to that expected based on the rates of star form…
