On the correlation between Ly forest opacity and galaxy density in late reionization models
Nakul Gangolli, Anson D'Aloisio, Christopher Cain +2
The relationship between Ly forest opacity and local galaxy density (the opacity-density relation) is a key observational test of late reionization models. Using narrow-band sur…
The relationship between IGM Lyman-alpha opacity and galaxy density near the end of reionization
Holly M. Christenson, George D. Becker, Anson D'Aloisio +6
Observed scatter in the Lyman-alpha opacity of quasar sightlines at has motivated measurements of the correlation between Ly opacity and galaxy density, as models that pre…
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…
Long Dark Gaps in the Ly Forest at : Evidence of Ultra Late Reionization from XQR-30 Spectra
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +22
We present a new investigation of the intergalactic medium (IGM) near reionization using dark gaps in the Lyman- (Ly) forest. With its lower optical depth, Ly offers a pot…
Constraints on the End of Reionization from the Density Fields Surrounding Two Highly Opaque Quasar Sightlines
Holly M. Christenson, George D. Becker, Steven R. Furlanetto +5
The observed large-scale scatter in Lyman opacity of the intergalactic medium at implies large fluctuations in the neutral hydrogen fraction that are unexpected long afte…
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 mean free path of ionizing photons at 5 < z < 6: evidence for rapid evolution near reionization
George D. Becker, Anson D'Aloisio, Holly M. Christenson +3
The mean free path of ionizing photons, , is a key factor in the photoionization of the intergalactic medium (IGM). At , however, may be sho…
Keck/OSIRIS IFU Detection of a z 3 Damped Lyman Alpha Host Galaxy
Holly M. Christenson, Regina A. Jorgenson
We present Keck/OSIRIS infrared IFU observations of the 3.153 sub-DLA DLA2233+131, previously detected in absorption to a background quasar and studied with single slit spec…
