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 ...

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

Blanc, Guillermo A.; Adams, Joshua J.; Gebhardt, Karl; Hill, Gary J.; Drory, Niv; Hao, Lei; Bender, Ralf; Ciardullo, Robin; Finkelstein, Steven L.; Fry, Alexander B.; Gawiser, Eric; Gronwall, Caryl; Hopp, Ulrich; Jeong, Donghui; Kelzenberg, Ralf; Komatsu, Eiichiro; MacQueen, Phillip; Murphy, Jeremy D.; Roth, Martin M.; Schneider, Donald P.; Tufts, Joseph (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 Rest-Frame Ultraviolet Spectra Of UV-Selected Active Galactic Nuclei At Z Similar To 2-3

Hainline, Kevin N.; Shapley, Alice E.; Greene, Jenny E.; Steidel, Charles C. (2011-05)

We present new results for a sample of 33 narrow-lined UV-selected active galactic nuclei (AGNs), identified in the course of a spectroscopic survey for star-forming galaxies at z similar to 2-3. The rest-frame UV composite ...

Insights On The Formation, Evolution, And Activity Of Massive Galaxies From Ultracompact And Disky Galaxies At Z=2-3

Weinzirl, Tim; Jogee, Shardha; Conselice, Christopher J.; Papovich, Casey; Chary, Ranga-Ram; Bluck, Asa; Grutzbauch, Ruth; Buitrago, Fernando; Mobasher, Bahram; Lucas, Ray A.; Dickinson, Mark; Bauer, Amanda E. (2011-12)

We present our results on the structure and activity of massive galaxies at z = 1-3 using one of the largest (166 with M-star >= 5 x 10(10) M-circle dot) and most diverse samples of massive galaxies derived from the ...
