Influence of the Spectral Energy Distribution of Reionization-Era Sources on the Lyman- Forest

Arghyadeep Basu, Benedetta Ciardi, James S. Bolton +2

Interpreting Lyman- forest properties during the epoch of reionization requires assumptions about the spectral energy distribution (SED) of ionizing sources. These are often sim…

Constraining Mixed Dark Matter models with high redshift Lyman-alpha forest data

Olga Garcia-Gallego, Vid Iršič, Martin G. Haehnelt +2

This study sets new constraints on Cold+Warm Dark Matter (CWDM) models by leveraging the small-scale suppression of structure formation imprinted in the Lyman- forest. Using the…

Constraints on Primordial Magnetic Fields from the Lyman-α forest

Mak Pavičević, Vid Iršič, Matteo Viel +5

We present the first constraints on primordial magnetic fields from the Lyman- forest using full cosmological hydrodynamic simulations. At the scales and redshifts probed by the…

The ionizing photon budget and effective clumping factor in radiative transfer simulations calibrated to Lyman-alpha forest data

Shikhar Asthana, Girish Kulkarni, Martin G. Haehnelt +3

Recent JWST observations have allowed for the first time to obtain comprehensive measurements of the ionizing photon production efficiency for a wide range of reion…

Constraints on dark photon dark matter from Lyman- forest simulations and an ultra-high signal-to-noise quasar spectrum

Andrea Trost, James S. Bolton, Andrea Caputo +3

The ultralight dark photon is a well-motivated, hypothetical dark matter candidate. In a dilute plasma, they can resonantly convert into photons, and heat up the intergalactic medi…

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…
