Defining the intrinsic AGN infrared spectral energy distribution and measuring its contribution to the infrared output of composite galaxies (2011)
Journal Article
Mullaney, J., Alexander, D., Goulding, A., & Hickox, R. (2011). Defining the intrinsic AGN infrared spectral energy distribution and measuring its contribution to the infrared output of composite galaxies. Monthly Notices of the Royal Astronomical Society, 414(2), 1082-1110. https://doi.org/10.1111/j.1365-2966.2011.18448.x

We use infrared spectroscopy and photometry to empirically define the intrinsic mid- to far-infrared spectral energy distribution (i.e. 6–100 μm SED) of thermal emission produced by typical (i.e. 2–10 keV luminosity, L2-10 keV∼ 1042–1044 erg s−1) act...

Clustering of Obscured and Unobscured Quasars in the Boötes Field: Placing Rapidly Growing Black Holes in the Cosmic Web (2011)
Journal Article
Hickox, R., Myers, A., Brodwin, M., Alexander, D., Forman, W., Jones, C., …Mullaney, J. (2011). Clustering of Obscured and Unobscured Quasars in the Boötes Field: Placing Rapidly Growing Black Holes in the Cosmic Web. Astrophysical Journal, 731(2), Article 117. https://doi.org/10.1088/0004-637x/731/2/117

We present the first measurement of the spatial clustering of mid-infrared-selected obscured and unobscured quasars, using a sample in the redshift range 0.7 < z < 1.8 selected from the 9 deg2 Boötes multiwavelength survey. Recently, the Spitzer Spac... Read More about Clustering of Obscured and Unobscured Quasars in the Boötes Field: Placing Rapidly Growing Black Holes in the Cosmic Web.

X-Ray Spectral Constraints for z ≈ 2 Massive Galaxies: The Identification of Reflection-dominated Active Galactic Nuclei (2011)
Journal Article
Alexander, D., Bauer, F., Brandt, W., Daddi, E., Hickox, R., Lehmer, B., …Vignali, C. (2011). X-Ray Spectral Constraints for z ≈ 2 Massive Galaxies: The Identification of Reflection-dominated Active Galactic Nuclei. Astrophysical Journal, 738(1), Article 44. https://doi.org/10.1088/0004-637x/738/1/44

We use the 4 Ms Chandra Deep Field-South (CDF-S) survey to place direct constraints on the ubiquity of z 2 heavily obscured active galactic nuclei (AGNs) in K < 22 BzK-selected galaxies. Forty-seven (21%) of the 222 BzK-selected galaxies in the centr...

CANDELS : constraining the AGN-merger connection with host morphologies at z ~ 2 (2011)
Journal Article
Kocevski, D., Faber, S., Mozena, M., Koekemoer, A., Nandra, K., Rangel, C., …Villforth, C. (2011). CANDELS : constraining the AGN-merger connection with host morphologies at z ~ 2. Astrophysical Journal, 744(2), Article 148. https://doi.org/10.1088/0004-637x/744/2/148

Using Hubble Space Telescope/WFC3 imaging taken as part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey, we examine the role that major galaxy mergers play in triggering active galactic nucleus (AGN) activity at z ~ 2. Our sampl... Read More about CANDELS : constraining the AGN-merger connection with host morphologies at z ~ 2.

Supermassive black hole growth in starburst galaxies over cosmic time : constraints from the deepest Chandra Fields (2011)
Journal Article
Rafferty, D., Brandt, W., Alexander, D., Xue, Y., Bauer, F., Lehmer, B., …Papovich, C. (2011). Supermassive black hole growth in starburst galaxies over cosmic time : constraints from the deepest Chandra Fields. Astrophysical Journal, 742(1), Article 3. https://doi.org/10.1088/0004-637x/742/1/3

We present an analysis of deep multiwavelength data for z ≈ 0.3-3 starburst galaxies selected by their 70 μm emission in the Extended-Chandra Deep Field-South and Extended Groth Strip. We identify active galactic nuclei (AGNs) in these infrared sourc...
