The Physical Nature of Rest-UV Galaxy Morphology During the Peak Epoch of Galaxy Formation
David R. Law, Charles C. Steidel, Dawn K. Erb +5
Motivated by the irregular and little-understood morphologies of z ~ 2 - 3 galaxies, we use non-parametric coefficents to quantify the morphologies of 216 galaxies which have been…
A Spectroscopic Survey of Redshift 1.4<z<3.0 Galaxies in the Goods-North Field: Survey Description, Catalogs, and Properties
Naveen A. Reddy, Charles C. Steidel, Dawn K. Erb +2
We present the results of a spectroscopic survey with the Keck I telescope of more than 280 star-forming galaxies and AGN at redshifts 1.4<z<3.0 in the GOODS-N field. Candidates ar…
Intergalactic CIV absorption at redshifts 5.4 to 6
Emma V. Ryan-Weber, Max Pettini, Piero Madau
We report the discovery of a strong CIV 1548,1550 absorption system at z_abs = 5.7238 in the near-infrared spectrum (J-band) of the z_em = 6.28 QSO SDSS J1030+0524. These observati…
The Direct Detection of Lyman-Continuum Emission from Star-forming Galaxies at z~3
Alice E. Shapley, Charles C. Steidel, Max Pettini +2
We present the results of rest-frame ultraviolet spectroscopic observations of a sample of 14 z~3 star-forming galaxies in the SSA22a field. These spectra are characterized by unpr…
The Stellar, Gas and Dynamical Masses of Star-Forming Galaxies at z~2
Dawn K. Erb, Charles C. Steidel, Alice E. Shapley +3
We present analysis of the near-infrared spectra of 114 rest-frame UV-selected star-forming galaxies at z~2. By combining the H-alpha spectra with photometric measurements from obs…
Chemical Elements at High and Low Redshifts
Max Pettini
The past few years have seen a steady progress in the determination of element abundances at high redshifts, with new and more accurate measures of metallicities in star-forming ga…
