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 Álvarez-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…
