The HETDEX Pilot Survey. III. The Low Metallicities Of High-Redshift Ly Alpha Galaxies

Finkelstein, Steven L.; Hill, Gary J.; Gebhardt, Karl; Adams, Joshua; Blanc, Guillermo A.; Papovich, Casey; Ciardullo, Robin; Drory, Niv; Gawiser, Eric; Gronwall, Caryl; Schneider, Donald P.; Tran, Kim-Vy (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 ...

Demographics of Bulge Types Within 11 Mpc and Implications for Galaxy Evolution

Fisher, David B.; Drory, Niv (2011-06)

We present an inventory of galaxy bulge types (elliptical galaxy, classical bulge, pseudobulge, and bulgeless galaxy) in a volume-limited sample within the local 11 Mpc sphere using Spitzer 3.6 mu m and Hubble Space Telescope ...
