• "Active galactic nuclei selected from galex spectroscopy: The ionizing source of spectrum at z similar to 1"

Barger AJ, Cowie LL, Astrophysical Journal 718(2): 1235-1242 Aug 2010.  For the first time, the authors are able to construct the shape of the ionizing background at z similar to 1 in a fully self-consistent way. 

• "High-sensitivity array observations of the z=1.87 submillimeter galaxy goods 850-3"

Momjian E, Wang WH, Knudsen KK, et al., Astronomical Journal 139 (4): 1622-1627 Apr 2010. We present sensitive phase-referenced Very Long Baseline Interferometry (VLBI) results on the radio continuum emission from the z = 1.87 luminous submillimeter galaxy (SMG) GOODS 850-3.

• "LOW-REDSHIFT Ly alpha SELECTED GALAXIES FROM GALEX SPECTROSCOPY: A COMPARISON WITH BOTH UV-CONTINUUM SELECTED GALAXIES AND HIGH-REDSHIFT Ly alpha EMITTERS"

Cowie LL, Barger AJ, Hu EM, Astrophysical Journal 711 (2): 928-958 Mar 2010. We construct a sample of low-redshift Ly alpha emission-line selected sources from Galaxy Evolution Explorer (GALEX) grism spectroscopy of nine deep fields to study the role of Lya emission in galaxy populations with cosmic time.

• "An extremely deep, wide-field near-infared survey: bright galaxy counts and local large scale structure"

Keenan RC, Trouille L, Barger AJ, et al., Astrophysical Journal Supplement Series 186 (1): 94-110 Jan 2010. We present a deep, wide-field near-infrared (NIR) survey over five widely separated fields at high Galactic latitude covering a total of similar to 3 deg(2) in J, H, and K-s.

• "The OPTX project III: X-ray versus optical spectral type for active galactic nuclei"

Trouille L, Barger AJ, Cowie LL, et al., Atrophysical Journal 703 (2): 2160-2170 Oct 2009. We compare the optical spectral types with the X-ray spectral properties for a uniformly selected (sources with fluxes greater than the 3 sigma level and above a flux limit of f(2-8 keV) > 3.5 x 10(-15) erg cm(-2) s(-1)), highly spectroscopically complete (> 80% for f(2-8 keV) > 10(-14) erg cm(-2) s(-1) and > 60% below) 2-8 keV X-ray sample observed in three Chandra fields (CLANS, CLASXS, and the CDF-N) that cover similar to 1.2 deg(2).
