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 si…
Constraints on Primordial Magnetic Fields from the Lyman-α forest
Mak PaviÄeviÄ, Vid IrÅ¡iÄ, 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 th…
Constraining Mixed Dark Matter models with high redshift Lyman-alpha forest data
Olga Garcia-Gallego, Vid IrÅ¡iÄ, 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 th…
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…
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…
Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES
Valentina D'Odorico, James S. Bolton, Lise Christensen +21
High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium…
