The SPHINX public data release. II. Using low-ionisation absorption lines and dust attenuation to predict Lyman continuum escape

Valentin Mauerhofer, Jérémy Blaizot, Thibault Garel +11

Low-ionisation state (LIS) absorption lines, such as SiII 1526, are widely used to trace the properties of the interstellar medium (ISM) in galaxies. These lines provide crucial in…

The Lyman-alpha and Continuum Origins Survey II: the connection between the escape of ionizing radiation and Lyman-alpha halos in star-forming galaxies

A. Saldana-Lopez, M. J. Hayes, A. Le Reste +24

One of the current challenges in galaxy evolution studies is to establish the mechanisms that govern the escape of ionizing radiation from galaxies. Here, we investigate the connec…

Extended red wings and the visibility of reionization-epoch Lyman- emitters

Yuxuan Yuan, Sergio Martin-Alvarez, Martin G. Haehnelt +4

The visibility of the Lyman- (Ly) emission from reionization-epoch galaxies depends sensitively on the extent of the intrinsic \lya emission redwards of 1215.67~Ã . The pro…

Radiative transfer of Lyman- photons at cosmic dawn with realistic gas physics

Shikhar Mittal, Girish Kulkarni, Thibault Garel

Lyman- photons enable the cosmic dawn 21-cm signal through a process called the Wouthuysen-Field effect. An accurate model of the signal in this epoch hinges on the accuracy of…

Ly emission as a sensitive probe of feedback-regulated LyC escape from dwarf galaxies

Yuxuan Yuan, Sergio Martin-Alvarez, Martin G. Haehnelt +2

Ly emission is an exceptionally informative tracer of the life cycle of evolving galaxies and the escape of ionising photons. However, theoretical studies of Ly emission ar…
