The Varied Fates of z~2 Star-forming Galaxies
Charlie Conroy, Alice E. Shapley, Jeremy L. Tinker +2
Star-forming galaxies constitute the majority of galaxies with stellar masses >10^10 M_Sun/h^2 at z~2 and dominate the star-formation rate density of the Universe at this early epo…
A Keck Survey for Gravitationally-Lensed Lyman-alpha Emitters in the Redshift Range 8.5 < z < 10.4: New Constraints on the Contribution of Low Luminosity Sources to Cosmic Reionization
Daniel P. Stark, Richard S. Ellis, Johan Richard +3
We discuss new observational constraints on the abundance of faint high redshift Lyman-alpha emitters secured from a deep Keck near-infrared spectroscopic survey which utilizes the…
Metal-Poor Globular Clusters and the Formation of Their Host Galaxies
K. L. Rhode, S. E. Zepf, M. R. Santos
We have determined the total numbers and specific frequencies of blue, metal-poor globular clusters (GCs) in eight spiral and early-type galaxies. These data, along with five measu…
A Probable z~7 Galaxy Strongly Lensed by the Rich Cluster Abell 2218: Exploring the Dark Ages
Jean-Paul Kneib, Richard S. Ellis, Michael R. Santos +1
We discuss the observational properties of a remarkably faint triply-imaged galaxy revealed in a deep z-band ACS observation of the lensing cluster A2218. A well-constrained mass m…
The Abundance of Low-luminosity Lyman alpha Emitters at High Redshift
Michael R. Santos, Richard S. Ellis, Jean-Paul Kneib +2
We derive the luminosity function of high-redshift Lyman alpha emitting sources from a deep, blind, spectroscopic survey that utilized strong-lensing magnification by intermediate-…
Searches for high redshift galaxies using gravitational lensing
J. Richard, R. Pello, J. -P. Kneib +3
We present different methods used to identify high redshift (z>5) objects in the high-magnification regions of lensing galaxy clusters, taking advantage of very well constrained le…
Probing reionization with Lyman-alpha emission lines
Michael R. Santos
Lyman-alpha emission from high-redshift galaxies may be a powerful probe of the ionization history of the IGM at z>6: the observed Lyman-alpha emission line is sensitive to the neu…
A method to infer the stellar population that dominated the UV background at the end of reionization
Michael R. Santos, Abraham Loeb
We present an observational test of the spectrum of the ionizing background at z~5; the test is sufficiently sensitive to determine whether Pop II or Pop III stars are the dominant…
The Contribution of the First Stars to the Cosmic Infrared Background
Michael R. Santos, Volker Bromm, Marc Kamionkowski
We calculate the contribution to the cosmic infrared background from very massive metal-free stars at high redshift. We explore two plausible star-formation models and two limiting…
A Faint Star-Forming System Viewed Through the Lensing Cluster Abell 2218: First Light at z~5.6?
Richard Ellis, Mike Santos, Jean-Paul Kneib +1
We discuss the physical nature of a remarkably faint pair of Lyman alpha-emitting images discovered close to the giant cD galaxy in the lensing cluster Abell 2218 (z=0.18) during a…
