QSO Lyman-Alpha Absorbers and Galaxy Halos
Astrophysics and Space Science, 1998We review the current status of our survey of galaxies in fields of HST target QSOs, which has allowed us to identify the galaxies responsible for a number of Lyman-α absorption systems. We emphasize the use of QSO absorption lines to study the structure and kinematics of the large gaseous halos that virtually all galaxies appear to possess.

1989
Lyman — α emission dominates the UV spectra of the roughly 18 radio galaxies observed to date with z > 1.6. I discuss three categories of such objects; (a) “normal”, large and distant radio galaxies with developed continuum structures, often aligned with the radio source, (b) 2–3 “blobbier”, less symmetric objects with weaker continua, but still ...

Lyman-Alpha Galaxies at Large Redshifts
1988Strong Lyα emission has been detected from several different types of distant galaxies, radio galaxies and their companions at z ≃ 1.8, and galaxy companions of quasars at z > 3. This line emission is a good way of detecting galaxies at very large redshifts, and a powerful probe of the physical conditions and processes in them.

Lyman-alpha emission as a probe of galaxy environments
2016As a result of resonant scatterings off hydrogen atoms, Lya emission from star-forming galaxies provides a potential probe of the neutral gas environment around them. In order to determine the utility of Lya emission as a probe of gas environments we study the effects of environmental anisotropy on the observed Lya emission by performing radiative ...

Lyman Alpha Emission and Absorption in Local Galaxies
2019Lecture notes concerning observations of the Lyman alpha (Ly\(\alpha \)) transition of atomic hydrogen in low-redshift (z) galaxies. Section 1 discusses the main motivations, astrophysical prerequisites, and definitions. Section 2 describes the various instruments that have contributed to the field or are currently capable of observing Ly\(\alpha \) at
