A Significant Population of Very Luminous Dust-Obscured Galaxies at Redshift z ~ 2
Arjun Dey,B. T. Soifer,Vandana Desai,K. Brand,Emeric Le Floc'h,Michael J. I. Brown,Buell T. Jannuzi,Lee Armus,R. Shane Bussmann,Mark Brodwin,C. Bian,Peter Eisenhardt,Sarah J.U. Higdon,Daniel W. Weedman,Steven P. Willner +14 more
TL;DR: In this paper, a simple method for selecting high-redshift (z ~ 2) dust-obscured galaxies based solely on the ratio of the observed mid-infrared 24 μm to optical R-band flux density was presented.
The Evolving Luminosity Function of Red Galaxies
Buell T. Jannuzi,Michael J. I. Brown,Arjun Dey,K. Brand,Andrew J. Benson,Mark Brodwin,Darren J. Croton,Peter Eisenhardt +7 more
TL;DR: In this paper, the authors trace the assembly history of red galaxies since z = 1 by measuring their evolving space density with the B-band luminosity function, which is consistent with star-forming galaxies being transformed into L* red galaxies after a decline in their star formation rates.

Photometric Redshifts in the IRAC Shallow Survey
M. Brodwin,Michael J. I. Brown,M. L. N. Ashby,C. Bian,K. Brand,Arjun Dey,Peter Eisenhardt,Daniel J. Eisenstein,Anthony H. Gonzalez,J. S. Huang,Buell T. Jannuzi,Christopher S. Kochanek,E. McKenzie,Michael A. Pahre,Howard A. Smith,B. T. Soifer,S. A. Stanford,Daniel Stern,Richard Elston +18 more
TL;DR: In this article, a hybrid photometric redshift algorithm incorporating both neural-net and template-fitting techniques, calibrated with over 15,000 spectroscopic redshifts, was used to achieve a redshift accuracy of 0.06(1+z) for 95% of galaxies at 0 1) galaxy clusters.

The Active Galactic Nuclei Contribution to the Mid-Infrared Emission of Luminous Infrared Galaxies
K. Brand,Arjun Dey,Dan Weedman,Vandana Desai,E. Le Floc'h,Buell T. Jannuzi,B. T. Soifer,Michael J. I. Brown,Peter Eisenhardt,Varoujan Gorjian,C. Papovich,Howard A. Smith,S. P. Willner,Richard J. Cool +13 more
TL;DR: In this article, the contribution of AGN to the mid-IR emission of luminous infrared galaxies (LIRGs) at z > 0.6 was determined by measuring the midIR dust continuum slope of 20,039 mid IR sources, selected from a Spitzer MIPS survey of the NOAO Deep Wide-Field Survey Bootes field and corresponding 8 μm data from the IRAC Shallow Survey.
