The HETDEX Pilot Survey. III. The Low Metallicities Of High-Redshift Ly Alpha Galaxies
(2011-03)
We present the results of Keck/NIRSPEC spectroscopic observations of three Ly alpha emitting galaxies (LAEs) at z similar to 2.3 discovered with the HETDEX pilot survey. We detect H alpha, [OIII], and H beta emission from ...
The Spectrally Resolved Lyman-Alpha Emission Of Three Lyman-Alpha-Selected Field Galaxies At Z Similar To 2.4 From The HETDEX Pilot Survey
(2013-10)
We present new results on the spectrally resolved Ly alpha emission of three Ly alpha-emitting field galaxies at z similar to 2.4 with high Lya equivalent width (> 100 angstrom) and Lya luminosity (similar to 10(43) erg ...
The HETDEX Pilot Survey. IV. The Evolution Of O II Emitting Galaxies From Z Similar To 0.5 To Z Similar To 0
(2013-05)
We present an analysis of the luminosities and equivalent widths of the 284 z < 0.56 [O II]-emitting galaxies found in the 169 arcmin(2) pilot survey for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). By ...
The HETDEX Pilot Survey. II. The Evolution Of The Ly Alpha Escape Fraction From The Ultraviolet Slope And Luminosity Function Of 1.9 < Z < 3.8 Laes
(2011-07)
We study the escape of Ly alpha photons from Ly alpha emitting galaxies (LAEs) and the overall galaxy population using a sample of 99 LAEs at 1.9 < z < 3.8 detected through integral-field spectroscopy of blank fields by ...
The HETDEX Pilot Survey. V. The Physical Origin Of Ly Alpha Emitters Probed By Near-Infrared Spectroscopy
(2014-08)
We present the results from a Very Large Telescope/SINFONI and Keck/NIRSPEC near-infrared spectroscopic survey of 16 Ly alpha emitters (LAEs) at z = 2.1-2.5 in the COSMOS and GOODS-N fields discovered from the Hobby Eberly ...
Spectral Energy Distribution Fitting Of HETDEX Pilot Survey Ly Alpha Emitters In Cosmos And GOODS-N
(2014-05)
We use broadband photometry extending from the rest-frame UV to the near-IR to fit the individual spectral energy distributions of 63 bright (L(Ly alpha) > 10(43) erg s(-1)) Ly alpha emitting galaxies (LAEs) in the redshift ...
The HETDEX Pilot Survey. I. Survey Design, Performance, and Catalog of Emission-Line Galaxies
(2011-01)
We present a catalog of emission-line galaxies selected solely by their emission-line fluxes using awide-field integral field spectrograph. This work is partially motivated as a pilot survey for the upcoming Hobby-Eberly ...
The Central Dark Matter Distribution Of NGC 2976
(2012-01)
We study the mass distribution in the late-type dwarf galaxy NGC 2976 through stellar kinematics obtained with the Visible Integral Field ReplicableUnit Spectrograph Prototype and anisotropic Jeans models as a test of ...
Dwarf Galaxy Dark Matter Density Profiles Inferred From Stellar And Gas Kinematics
(2014-07)
We present new constraints on the density profiles of dark matter (DM) halos in seven nearby dwarf galaxies from measurements of their integrated stellar light and gas kinematics. The gas kinematics of low-mass galaxies ...
