Low Ly Visibility in Galaxy Overdensities: Reionization Topology and Neutral-Fraction Ceilings from DIVER over

Yongda Zhu, Xiaohui Fan, Laura C. Keating +19

Ly-alpha emission is widely used to trace cosmic reionization, but its interpretation depends on how Ly-alpha visibility varies with galaxy environment. We use deep JWST/NIRSpec ob…

TORRCH: Tomographic reconstruction of the reionization of cosmic hydrogen with Ly emitters and non-Ly-selected galaxies

Soumak Maitra, Girish Kulkarni, Vipul Arora +5

Tomographic reconstruction of reionization is a long-sought goal. It would move the field beyond global summary statistics, such as the volume-averaged ionised fraction, to direct,…

The Lyman- emitter bispectrum as a probe of reionization morphology

Soumak Maitra, Girish Kulkarni, Shikhar Asthana +3

Ly emitters (LAEs) have now been discovered out to redshift , and are valuable probes of the reionization history at redshifts beyond the reach of other currently availab…

The impact of faint AGN discovered by JWST on reionization

Shikhar Asthana, Martin G. Haehnelt, Girish Kulkarni +4

The relative contribution of emission from stellar sources and accretion onto supermassive black holes to reionization has been brought into focus again by the apparent high abunda…

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…

Chronicling the reionization history at with emergent quasar damping wings

Dominika Ďurovčíková, Anna-Christina Eilers, Huanqing Chen +6

The spectra of high-redshift () quasars contain valuable information on the progression of the Epoch of Reionization (EoR). At redshifts , the observed Lyman-serie…
