Deciphering spatially resolved Lyman-alpha profiles in reionization analogs: the Sunburst Arc at cosmic noon

Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen +7

The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons,…
