Abundances at High Redshifts: The Chemical Enrichment History of Damped Lyα Galaxies [PDF]
, 1996 We study the elemental abundances of C, N, O, Al, Si, S, Cr, Mn, Fe, Ni, and Zn in a sample of 14 damped Lyα systems (galaxies) with H I column density N(H I) ⩾ 1020 cm−2, using high-quality spectra quasars obtained with the 10 m Keck telescope.

Lyα Halos around [O iii]-selected Galaxies in HETDEX [PDF]
Astrophysical Journal Letters, 2022 We present extended Lyα emission out to 800 kpc of 1034 [O iii]-selected galaxies at redshifts 1.9 < z < 2.35 using the Hobby–Eberly Telescope Dark Energy Experiment. The locations and redshifts of the galaxies are taken from the 3D-HST survey.

Cosmology from clustering of Lyα galaxies: breaking non-gravitational Lyα radiative transfer degeneracies using the bispectrum [PDF]
, 2012 Large surveys for Lyman-alpha emitting (LAE) galaxies have been proposed as a new method for measuring clustering of the galaxy population at high redshift with the goal of determining cosmological parameters.

Low-Redshift Damped Lyα Galaxies toward the Quasars B2 0827+243, PKS 0952+179, PKS 1127–145, and PKS 1629+120 [PDF]
, 2002 We present optical and near-infrared ground-based imaging results on four low-redshift damped Lyα (DLA) galaxies. The corresponding DLA systems were discovered in our Hubble Space Telescope spectroscopic surveys for DLA lines in known strong Mg II ...

The Effects of Stellar Population and Gas Covering Fraction on the Emergent Lyα Emission of High-redshift Galaxies [PDF]
Astrophysical Journal, 2021 We perform joint modeling of the composite rest-frame far-UV and optical spectra of redshift 1.85 ≤ z ≤ 3.49 star-forming galaxies to deduce key properties of the massive stars, ionized interstellar medium (ISM), and neutral ISM, with the aim of ...

The Ages and Masses of Lyα Galaxies at z ~ 4.5 [PDF]
, 2006 We examine the stellar populations of a sample of 98 z ~ 4.5 Lyα-emitting galaxies using their broadband colors derived from deep photometry at the Multiple Mirror Telescope (MMT).

The Compact UV Size of Green Pea Galaxies As Local Analogs of High-redshift Lyα-Emitters [PDF]
Astrophysical Journal, 2021 We study the dependence of Lyα escape from galaxies on UV continuum size and luminosity using a sample of 40 Green Pea (GP) galaxies, which are the best local analogs of high-redshift Lyα emitters (LAEs).

THE HETDEX PILOT SURVEY. III. THE LOW METALLICITIES OF HIGH-REDSHIFT Lyα GALAXIES [PDF]
, 2010 We present the results of Keck/NIRSPEC spectroscopic observations of three Lyα emitting galaxies (LAEs) at z∼ 2.3 discovered with the HETDEX pilot survey. We detect Hα, [O iii], and Hβ emission from two galaxies at z= 2.29 and 2.49, designated HPS194 and

CLEAR: Boosted Lyα Transmission of the Intergalactic Medium in UV-bright Galaxies [PDF]
Astrophysical Journal, 2021 Reionization is an inhomogeneous process, thought to begin in small ionized bubbles of the intergalactic medium (IGM) around overdense regions of galaxies.
