Lyman-Alpha Galaxies in 1988

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 emission as a probe of galaxy environments

2016
As 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

2019
Lecture 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
