Chronicling the reionization history at 6≲z≲7 with emergent quasar damping wings

Dominika Ďurovčíková, Anna-Christina Eilers, Huanqing Chen +6

The spectra of high-redshift (z≳6) quasars contain valuable information on the progression of the Epoch of Reionization (EoR). At redshifts z<6, the observed Lyman-serie…

Studying the Reionization Epoch with QSO Absorption Lines

George D. Becker, Anson D'Aloisio, Frederick B. Davies +2

Absorption signatures in the spectra of QSOs are one of our most powerful tools for studying galactic and intergalactic environments at high redshifts. With the discovery of QSOs o…

Extremely metal-poor gas at a redshift of 7

Robert A. Simcoe, Peter W. Sullivan, Kathy L. Cooksey +3

In typical astrophysical environments, the abundance of heavy elements ranges from 0.001 to 2 times the solar concentration. Lower abundances have been seen in select stars in the…
