To Stack or Not to Stack: Spectral Energy Distribution Properties of Lya-Emitting Galaxies at z=2.1
Carlos J. Vargas, Hannah Bish, Viviana Acquaviva +13
We use the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) GOODS-S multi-wavelength catalog to identify counterparts for 20 Lya Emitting (LAE) galaxies at…
Spectroscopic Needs for Imaging Dark Energy Experiments: Photometric Redshift Training and Calibration
J. Newman, A. Abate, F. Abdalla +58
Large sets of objects with spectroscopic redshift measurements will be needed for imaging dark energy experiments to achieve their full potential, serving two goals:_training_, i.e…
The Spectrally Resolved Lyman-alpha Emission of Three Lyman-alpha Selected Field Galaxies at z~2.4 from the HETDEX Pilot Survey
Taylor S. Chonis, Guillermo A. Blanc, Gary J. Hill +11
We present new results on the spectrally resolved Lyman-alpha (LyA) emission of three LyA emitting field galaxies at z~2.4 with high LyA equivalent width (>100 Angstroms) and LyA l…
Galaxy redshift surveys with sparse sampling
Chi-Ting Chiang, Philipp Wullstein, Donghui Jeong +16
Survey observations of the three-dimensional locations of galaxies are a powerful approach to measure the distribution of matter in the universe, which can be used to learn about t…
Searching for Neutral Hydrogen Halos around z ~ 2.1 and z ~ 3.1 Ly-alpha Emitting Galaxies
John Feldmeier, Alex Hagen, Robin Ciardullo +9
We search for evidence of diffuse Ly-alpha emission from extended neutral hydrogen surrounding Ly-alpha emitting galaxies (LAEs) using deep narrow-band images of the Extended Chand…
