The primordial deuterium abundance of the most metal-poor damped Lyman-alpha system
Ryan Cooke, Max Pettini, Kenneth M. Nollett +1
We report the discovery and analysis of the most metal-poor damped Lyman-alpha (DLA) system currently known, which also displays the Lyman series absorption lines of neutral deuter…
Non-Equilibrium Populations of Hydrogen in High-Redshift Galaxies
Brian B. Pomerantz, Kayla Redmond, Vladimir Strelnitski
We investigate the possibility of maser amplification in hydrogen recombination lines from the galaxies of first generation, at z<~30. Combining analytical and computational approa…
G2C2 I: Homogeneous SDSS photometry for Galactic GCs
Joachim Vanderbeke, Michael J. West, Roberto De Propris +8
We present and aperture photometry for 96 Galactic Globular Clusters, making this the largest homogeneous catalog of photometry for these objects in the SDSS…
High-n Hydrogen Recombination Lines from the First Galaxies
Evan Rule, Abraham Loeb, Vladimir Strelnitski
We investigate the prospects of blind and targeted searches in the radio domain (10 MHz to 1 THz) for high-n hydrogen recombination lines from the first generation of galaxies, at…
The Rich Globular Cluster System of Abell 1689 and the Radial Dependence of the Globular Cluster Formation Efficiency
K. A. Alamo-Martínez, J. P. Blakeslee, M. J. Jee +7
We study the rich globular cluster (GC) system in the center of the massive cluster of galaxies Abell 1689 (z=0.18), one of the most powerful gravitational lenses known. With 28 HS…
