Constraints on the Evolution of the Ionizing Background and Ionizing Photon Mean Free Path at the End of Reionization

Frederick B. Davies, Sarah E. I. Bosman, Prakash Gaikwad +16

The variations in Ly forest opacity observed at between lines of sight to different background quasars are too strong to be caused by fluctuations in the density field a…

A modified lognormal approximation of the Lyman- forest: comparison with full hydrodynamic simulations at

Bhaskar Arya, Tirthankar Roy Choudhury, Aseem Paranjape +1

Observations of the Lyman- forest in distant quasar spectra with upcoming surveys are expected to provide significantly larger and higher-quality datasets. To interpret these da…

Unveiling Dark Matter free-streaming at the smallest scales with high redshift Lyman-alpha forest

Vid Iršič, Matteo Viel, Martin G. Haehnelt +8

This study introduces novel constraints on the free-streaming of thermal relic warm dark matter (WDM) from Lyman- forest flux power spectra. Our analysis utilises a high-resolut…

Probing Ultra-late Reionization: Direct Measurements of the Mean Free Path over

Yongda Zhu, George D. Becker, Holly M. Christenson +22

The mean free path of ionizing photons, , is a critical parameter for modeling the intergalactic medium (IGM) both during and after reionization. We present direct mea…

XQR-30: the ultimate XSHOOTER quasar sample at the reionization epoch

Valentina D'Odorico, E. Banados, G. D. Becker +46

The final phase of the reionization process can be probed by rest-frame UV absorption spectra of quasars at z>6, shedding light on the properties of the diffuse intergalactic mediu…

Measuring the photo-ionization rate, neutral fraction and mean free path of HI ionizing photons at from a large sample of XShooter and ESI spectra

Prakash Gaikwad, Martin G. Haehnelt, Frederick B. Davies +16

We measure the mean free path (), photo-ionization rate () and neutral fraction () of hydrogen in 12 redshif…

Role of ionizing background on the statistics of metal absorbers in hydrodynamical simulations

Sukanya Mallik, Raghunathan Srianand, Soumak Maitra +2

We study the statistical properties of O VI, C IV, and Ne VIII absorbers at low- (i.e., ) using Sherwood simulations with "WIND" only and "WIND+AGN" feedback and Massive…
