E-XQR-30: Evidence for an Increase in the Ionization State of Metal Absorbers from z~6 to z~2

Stephanie Rowlands, R. L. Davies, E. Ryan-Weber +15

We investigate the evolution of the ionization state of metal-enriched gas in and around galaxies near the epoch of reionization using a sample of 488 metal absorption systems at 4…

QUEST (Quasar Unsupervised Encoder and Synthesis Tool): A machine learning framework to generate quasar spectra

F. Guarneri, J. T. Schindler, R. A. Meyer +5

Quasars at the redshift frontier (z > 7.0) are fundamental probes of black hole (BH) growth and evolution but notoriously difficult to identify. At these redshifts, machine learnin…

Measuring photo-ionization rate and mean free path of HeII ionizing photons at $2.5 \leq z \leq 3.6$ : Evidence for late and rapid HeII reionization Part-II

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

We present measurements of the spatially averaged HeII photo-ionization rate ( $⟨ I^_{HeII} ⟩$ ), mean free path of HeII ionizing photons ( $I^»_{mfp, HeII}$ ), and…
