The Lyman Alpha Reference Sample XV. Relating Ionised Gas Kinematics with Lyman- observables
E. C. Herenz, A. Schaible, P. Laursen +9
Gas kinematics affect the radiative transfer and escape of hydrogen Lyman- (Ly) emission from galaxies. We investigate this interplay empirically by relating the ionised gas…

In recent years, a number of Lyman continuum (LyC) leaker candidates at intermediate redshifts have been found, providing insight into how the Universe was reionised at early cosmi…
On the evolution of the size of Lyman alpha halos across cosmic time: no change in the circumgalactic gas distribution when probed by line emission
Axel Runnholm, Matthew J. Hayes, Yu-Heng Lin +18
Lyman (Ly) is now routinely used as a tool for studying high-redshift galaxies and its resonant nature means it can trace neutral hydrogen around star-forming galaxies. Inte…
