Ground Layer Adaptive Optics for the W. M. Keck Observatory: Feasibility Study
J. R. Lu, M. Chun, S. M. Ammons +12
Ground-layer adaptive optics (GLAO) systems offer the possibility of improving the "seeing" of large ground-based telescopes and increasing the efficiency and sensitivity of observ…
The Sightline to Q2343-BX415: Clues to Galaxy Formation in a Quasar Environment
Samantha A. Rix, Max Pettini, Charles C. Steidel +4
(Abridged) We have discovered a strong DLA coincident in redshift with the faint QSO Q2343-BX415 (R = 20.2, z_em = 2.57393). Follow-up observations at intermediate spectral resolut…
H-alpha Observations of a Large Sample of Galaxies at z~2: Implications for Star Formation in High Redshift Galaxies
Dawn K. Erb, Charles C. Steidel, Alice E. Shapley +3
Using H-alpha spectra of 114 rest-frame UV-selected galaxies at z~2, we compare inferred star formation rates (SFRs) with those determined from the UV continuum luminosity. After c…
Galaxy Morphology - Halo Gas Connections
Glenn G. Kacprzak, Christopher W. Churchill, Charles C. Steidel
We studied a sample of 38 intermediate redshift MgII absorption-selected galaxies using (1) Keck/HIRES and VLT/UVES quasar spectra to measure the halo gas kinematics from MgII abso…
Type Ia Supernova Discoveries at z>1 From the Hubble Space Telescope: Evidence for Past Deceleration and Constraints on Dark Energy Evolution
Adam G. Riess, Louis-Gregory Strolger, John Tonry +16
We have discovered 16 Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to provide the first conclusive evidence for cosmic deceleration that pre…
Lyman Break Galaxies at z>4 and the Evolution of the UV Luminosity Density at High Redshift
C. C. Steidel, K. L. Adelberger, M. Giavalisco +2
We present initial results of a survey for star-forming galaxies in the redshift range 3.8 < z < 4.5. This sample consists of a photometric catalog of 244 galaxies culled from a to…
