Chemical Signatures of the First Supernovae in the Sculptor Dwarf Spheroidal Galaxy
Joshua D. Simon, Heather R. Jacobson, Anna Frebel +3
We present a homogeneous chemical abundance analysis of five of the most metal-poor stars in the Sculptor dwarf spheroidal galaxy. We analyze new and archival high resolution spect…
Mass production of volume phase holographic gratings for the VIRUS spectrograph array
Taylor S. Chonis, Amy Frantz, Gary J. Hill +7
The Visible Integral-field Replicable Unit Spectrograph (VIRUS) is a baseline array of 150 copies of a simple, fiber-fed integral field spectrograph that will be deployed on the Ho…
Dwarf Galaxy Dark Matter Density Profiles Inferred from Stellar and Gas Kinematics
Joshua J. Adams, Joshua D. Simon, Maximilian H. Fabricius +9
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 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…
Dusty OB stars in the Small Magellanic Cloud - II: Extragalactic Disks or Examples of the Pleiades Phenomenon?
Joshua J. Adams, Joshua D. Simon, Alberto D. Bolatto +6
We use mid-infrared Spitzer spectroscopy and far-infrared Herschel photometry for a sample of twenty main sequence O9--B2 stars in the Small Magellanic Cloud (SMC) with strong 24 m…
The HETDEX Pilot Survey. IV. The Evolution of [O II] Emitting Galaxies from z ~ 0.5 to z ~ 0
Robin Ciardullo, Caryl Gronwall, Joshua J. Adams +10
We present an analysis of the luminosities and equivalent widths of the 284 z < 0.56 [O II]-emitting galaxies found in the 169 square arcmin pilot survey for the Hobby-Eberly Teles…
