The Lyman Continuum Escape Fraction of The Cosmic Horseshoe: A Test of Indirect Estimates
Kaveh Vasei, Brian Siana, Alice E. Shapley +6
High redshift star-forming galaxies are likely responsible for the reionization of the Universe, yet direct detection of their escaping ionizing (Lyman continuum) photons has prove…
Testing metallicity indicators at z~1.4 with the gravitationally lensed galaxy CASSOWARY 20
Bethan L. James, Max Pettini, Lise Christensen +6
We present X-shooter observations of CASSOWARY 20 (CSWA 20), a star-forming (SFR ~6 Msol/yr) galaxy at z=1.433, magnified by a factor of 11.5 by the gravitational lensing produced…
Galactic Outflows in Absorption and Emission: Near-UV Spectroscopy of Galaxies at 1<z<2
Dawn K. Erb, Anna M. Quider, Alaina L. Henry +1
We study large-scale outflows in a sample of 96 star-forming galaxies at 1<z<2, using near-UV spectroscopy of FeII and MgII absorption and emission. The average blueshift of the Fe…
The Pittsburgh Sloan Digital Sky Survey MgII Quasar Absorption-Line Survey Catalog
Anna M. Quider, Daniel B. Nestor, David A. Turnshek +4
We present a catalog of intervening MgII quasar absorption-line systems in the redshift interval 0.36 <= z <= 2.28. The catalog was built from Sloan Digital Sky Survey Data Release…
A Groundbased Imaging Study of Galaxies Causing DLA, subDLA, and LLS Absorption in Quasar Spectra
Sandhya M. Rao, Michele Belfort-Mihalyi, David A. Turnshek +3
We present results from a search for galaxies that give rise to damped Lyman alpha (DLA), subDLA, and Lyman limit system (LLS) absorption at redshifts 0.1 ~< z ~< 1 in the spectra…
Probing star formation across cosmic time with absorption line systems
Brice Ménard, Vivienne Wild, Daniel Nestor +2
We present an empirical connection between cold gas in galactic halos and star formation. Using a sample of more than 8,500 MgII absorbers from SDSS quasar spectra, we report the d…
A Study of Interstellar Gas and Stars in the Gravitationally Lensed Galaxy `The Cosmic Eye' from Rest-Frame Ultraviolet Spectroscopy
Anna M. Quider, Alice E. Shapley, Max Pettini +2
We report the results of a study of the rest-frame UV spectrum of the Cosmic Eye, a luminous Lyman break galaxy at z=3.07331 gravitationally lensed by a factor of 25. The spectrum,…
The Ultraviolet Spectrum of the Gravitationally Lensed Galaxy `The Cosmic Horseshoe': A Close-up of a Star-forming Galaxy at z = 2
Anna M. Quider, Max Pettini, Alice E. Shapley +1
Taking advantage of strong gravitational lensing, we have recorded the rest-frame UV spectrum of the z = 2.38115 galaxy `The Cosmic Horseshoe' (J1148+1930) at higher resolution and…
Lensing, reddening and extinction effects of MgII absorbers from z=0.4 to z=2
Brice Ménard, Daniel Nestor, David Turnshek +5
Using a sample of almost 7000 strong MgII absorbers with 0.4 < z < 2.2 detected in the SDSS DR4 dataset, we investigate the gravitational lensing and dust extinction effects they i…
The Environments of Ultra-strong Mg II Absorbers
Daniel B. Nestor, David A. Turnshek, Sandhya M. Rao +1
We present r'- or i'-band WIYN images of the fields of 15 Sloan Digital Sky Survey quasars that have spectra exhibiting intervening MgII absorption-line systems with rest equivalen…
The Metallicity - Kinematics Relation in Large-N(HI) Absorbers
David A. Turnshek, Sandhya M. Rao, Daniel B. Nestor +2
Sloan Digital Sky Survey (SDSS) quasar spectroscopy is yielding a database of strong low-ionization MgII absorbers over the redshift interval 0.36<z<2.28 which is over two orders o…
