Measuring the Density Fields around Bright Quasars at with XQR-30 Spectra
Huanqing Chen, Anna-Christina Eilers, Sarah E. I. Bosman +10
Measuring the density of the intergalactic medium using quasar sightlines in the epoch of reionization is challenging due to the saturation of Lyman- absorption. Near a luminous…
Chasing the Tail of Cosmic Reionization with Dark Gap Statistics in the Ly Forest over
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +14
We present a new investigation of the intergalactic medium (IGM) near the end of reionization using "dark gaps" in the Lyman-alpha (Ly) forest. Using spectra of 55 QSOs at $z_{\…
The Predicament of Absorption-Dominated Reionization: Increased Demands on Ionizing Sources
Frederick B. Davies, Sarah E. I. Bosman, Steven R. Furlanetto +2
The reionization epoch concludes when ionizing photons reach every corner of the Universe. Reionization has generally been assumed to be limited primarily by the rate at which gala…
Reionization and galaxy inference from the high-redshift Lyα forest
Yuxiang Qin, Andrei Mesinger, Sarah E. I. Bosman +1
The transmission of Lyman-α (Lyα) in the spectra of distant quasars depends on the density, temperature, and ionization state of the intergalactic medium (IGM). Therefore, high-red…
