On the Stellar Populations and Evolution of Star-Forming Galaxies at 6.3 < z < 8.6
Steven L. Finkelstein, Casey Papovich, Mauro Giavalisco +4
We study the physical characteristics of galaxies at 6.3 < z < 8.6, selected from deep near-infrared imaging with the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope…
Paschen-alpha Emission in the Gravitationally Lensed Galaxy SMM J163554.2+661225
Casey Papovich, Gregory Rudnick, Jane Rigby +5
We report the detection of the Paschen-alpha emission line in the z=2.515 galaxy SMM J163554.2+661225 using Spitzer spectroscopy. SMM J163554.2+661225 is a sub-millimeter-selected…
The Shining Future of UV Spectral Synthesis
Anne Pellerin, Steven L. Finkelstein
With the coming generation of instruments and telescopes capable of spectroscopy of high redshift galaxies, the spectral synthesis technique in the rest-frame UV and Far-UV range w…
Ly-alpha emitting galaxies at redshift z~4.5 in the LALA Cetus field
Jun-Xian Wang, Sangeeta Malhotra, James E. Rhoads +2
We present a large sample of Ly-alpha emitting galaxies spectroscopically confirmed at z~4.5, based on IMACS spectroscopic observations of candidate LAEs in the LALA Cetus field. W…
Turning Back the Clock: Inferring the History of the Eight O'clock Arc
Steven L. Finkelstein, Casey Papovich, Gregory Rudnick +5
We present the results from an optical and near-infrared spectroscopic study of the ultraviolet-luminous z = 2.73 galaxy, the 8 o'clock arc. Due to gravitational lensing, this gala…
A Plethora of AGN Among Lyman Alpha Galaxies at Low Redshift
Steven L. Finkelstein, Seth H. Cohen, Sangeeta Malhotra +4
We investigate the fraction of z ~ 0.3 Lyman alpha emitting galaxies (LAEs) which host active galactic nucleus activity, which is typically from 1 - 5% at 2 < z < 6. Using optical…
