Evidence for a ~300 Mpc Scale Under-density in the Local Galaxy Distribution
Ryan C. Keenan, Amy J. Barger, Lennox L. Cowie
Galaxy counts and recent measurements of the luminosity density in the near-infrared (NIR) have indicated the possibility that the local universe may be under-dense on scales of se…
Low-Redshift Ly-alpha Selected Galaxies from GALEX Spectroscopy: A Comparison with Both UV-Continuum Selected Galaxies and High-Redshift Ly-alpha Emitters
L. L. Cowie, A. J. Barger, E. M. Hu
We construct a sample of low-redshift Ly-alpha emission-line selected sources from GALEX grism spectroscopy of nine deep fields to study the role of Ly-alpha emission in galaxy pop…
Deep Spectroscopy of Ultra-Strong Emission Line Galaxies
Esther M. Hu, Lennox L. Cowie, Yuko Kakazu +1
Ultra strong emission-line galaxies (USELs) with extremely high equivalent widths (EW(H beta) > 30A) can be used to pick out galaxies of extremely low metallicity in the z=0-1 reds…
An Integrated Picture of Star Formation, Metallicity Evolution, and Galactic Stellar Mass Assembly
L. L. Cowie, A. J. Barger
We present an integrated study of star formation and galactic stellar mass assembly from z=0.05-1.5 and galactic metallicity evolution from z=0.05-0.9 using a very large and highly…
A Near-Infrared Analysis of the Submillimeter Background and the Cosmic Star-Formation History
W. -H. Wang, L. L. Cowie, A. J. Barger
We use new deep near-infrared (NIR) and mid-infrared (MIR) observations to analyze the 850m image of the GOODS HDF-N region. We show that much of the submillimeter background a…
Imaging Large Scale Structure in the X-ray Sky
Y. Yang, R. F. Mushotzky, A. J. Barger +3
We present the first results from a wide solid angle, moderately deep {\it Chandra} survey of the Lockman Hole North-West region. Our 9 ACIS-I fields cover an effective solid angle…
