Studying dark gaps in Ly- forest transmission with large reionization simulations
Barun Maity, Frederick B. Davies, Benedetta Spina +1
The physical conditions of the intergalactic medium (IGM) during the final stages of cosmic reionization () are not yet fully understood. Recent reports of unexpected…
Detecting the signature of helium reionization through 3HeII 3.46cm line-intensity mapping
Benedetta Spina, Cristiano Porciani, Sarah E. I. Bosman +4
Helium reionization is the most recent phase change of the intergalactic medium, yet its timing and main drivers remain uncertain. Among the probes to trace its unfolding, the 3.46…
A close look at the black hole masses and hot dusty toruses of the first quasars with MIRI-MRS
Sarah E. I. Bosman, Javier Ãlvarez-Márquez, Frederick B. Davies +29
The presence of supermassive black holes (SMBHs, ) at remains a puzzle. While their existence appears to require exotic formation or growth proce…
Measuring the IGM correlation length at 5<z<6.1: a fast change at the end of Reionization
Benedetta Spina, Sarah E. I. Bosman, Barun Maity +1
The Lyman- forest of high redshift quasars is a powerful probe of the late stages of the Epoch of Reionization (EoR), particularly through the presence of Gunn-Peterson troughs…
Signatures of warm dark matter in the cosmological density fields extracted using Machine Learning
Ander Artola, Sarah E. I. Bosman, Prakash Gaikwad +6
We aim to construct a machine-learning approach that allows for a pixel-by-pixel reconstruction of the intergalactic medium (IGM) density field for various warm dark matter (WDM) m…
