We develop a comprehensive theoretical model for Lyman-alpha (Ly$\alpha$) emission, from the scale of individual Ly$\alpha$ emitters (LAEs) to Ly$\alpha$ halos (LAHs), Ly$\alpha$ blobs (LABs), and Ly$\alpha$ filaments (LAFs) of the diffuse cosmic …
We present the median-stacked Lyman-α surface brightness profile of 968 spectroscopically selected Lyman-α emitting galaxies (LAEs) at redshifts 1.9
Extended Lyman-alpha emission around galaxies and quasars at high redshift -- Lyman-alpha halos (LAHs) -- are now commonly detected through stacking as well as surrounding individual galaxies. Despite the increasing samples and the extensive …
Lyman-$\alpha$ (Ly$\alpha$) spectra provide insights into the small-scale structure and kinematics of neutral hydrogen (HI) within galaxies as well as the ionization state of the intergalactic medium (IGM). The former defines the intrinsic spectrum …
