Disentangling the galactic and intergalactic components in 313 observed Lyman-alpha line profiles between redshift 0 and 5
Siddhartha Gurung-López, Chris Byrohl, Max Gronke +5
Lyman-Alpha (Lya) photons emitted in star-forming galaxies undergo complex radiative transfer through the interstellar (ISM), circumgalactic (CGM), and intergalactic medium (IGM),…

Anatomy of an ionized bubble: NIRCam grism spectroscopy of the double-peaked Lyman- emitter COLA1 and its environment
Alberto Torralba-Torregrosa, Jorryt Matthee, Rohan P. Naidu +10
The increasingly neutral intergalactic gas at impacts the Lyman- flux observed from galaxies. One luminous galaxy, COLA1, stands out because of its unique double-peaked L…
