We present an intermediate-resolution, high signal-to-noise ratio spectrum of the z = 2.7268 galaxy MS 1512-cB58 obtained with the Low Resolution Imaging Spectrograph (LRIS) on the Keck I telescope and covering the rest frame far-UV from 1150 to 1930 A. Gravitational lensing by a foreground cluster boosts the flux from MS 1512-cB58 by a factor of ~30 and provides the opportunity for a first quantitative study of the physical properties of star-forming galaxies at high redshift. The spectrum we…

Properties of the z = 2.73 galaxy, MS1512-cB58
MS1512-cB58 is an z=2.73 galaxy whose apparent brightness is amplified by30–50X due to gravitationally lensing. The restframe far-UV spectrum of cB58 that was obtained by Keck-I/LRISis `one of the
The Rest-Frame Optical Spectrum of MS 1512-cB58.
Moderate-resolution, near-IR spectroscopy of MS 1512-cB58 is presented, obtained during commissioning of the near-infrared spectrometer (NIRSPEC) on the Keck II telescope, and infer a high nitrogen abundance, which may argue for the presence of an older stellar population.
The Lyα Forest of a Lyman Break Galaxy: Very Large Telescope Spectra of MS 1512–cB58 at z = 2.724*
The high-redshift galaxy MS 1512-cB58 (z = 2.724, mV = 20.64) has been observed with the very efficient high-resolution UV-Visual Eschelle Spectograph on the Very Large Telescope. Although this is a
We present new results on the kinematics and spatial distribution of metal-enriched gas within ~125 kpc of star-forming ("Lyman break") galaxies at redshifts 2 ≲ z ≲ 3. In particular, we focus on
Rest-Frame Ultraviolet Spectra of z ∼ 3 Lyman Break Galaxies*
We present the results of a systematic study of the rest-frame UV spectroscopic properties of Lyman break galaxies (LBGs). The database of almost 1000 LBG spectra proves useful for constructing high
The Counterarc to MS 1512–cB58 and a Companion Galaxy*
We present near-infrared spectra of "A2," the primary counterarc to the gravitationally lensed galaxy MS 1512-cB58. The spectra show redshifted Hα, [N II], [O III], and Hβ at z = 2.729 ± 0.001. We

We present the results of a detailed study of the interstellar medium (ISM) of MS 1512-cB58 (cB58 for short), an ~L* Lyman break galaxy at z = 2.7276, based on new spectral observations obtained with
The Rest-Frame Optical Spectra of Lyman Break Galaxies: Star Formation, Extinction, Abundances, and Kinematics*
We present the first results of a spectroscopic survey of Lyman break galaxies (LBGs) in the near-infrared aimed at detecting the emission lines of [O II], [O III], and Hβ from the H II regions of
Medium‐resolution spectroscopy of FORJ0332−3557: probing the interstellar medium and stellar populations of a lensed Lyman‐break galaxy at z= 3.77★
We recently reported the discovery of FORJ0332-3557, a lensed Lyman-break galaxy at z = 3.77 in a remarkable example of strong galaxy-galaxy gravitational lensing. We present here a medium-resolution
