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…
Better Together: The Complex Interplay Between Radiative Cooling and Magnetic Draping
Fernando Hidalgo-Pineda, Ryan Jeffrey Farber, Max Gronke
Rapidly outflowing cold H-I gas is ubiquitously observed to be co-spatial with a hot phase in galactic winds, yet the ablation time of cold gas by the hot phase should be much shor…
Spectral Shapes of the Lya Emission from Galaxies. II. the influence of stellar properties and nebular conditions on the emergent Lya profiles

We demonstrate how the stellar and nebular conditions in star-forming galaxies modulate the emission and spectral profile of HI Lya emission line. We examine the net Lya output, ki…
