Updated dark pixel fraction constraints on reionization's end from the Lyman-series forests of XQR-30
Frederick B. Davies, Sarah E. I. Bosman, Valentina D'Odorico +16
The fraction of "dark pixels" in the Ly and other Lyman-series forests at provides a powerful constraint on the end of the reionization process. Any spectral region…
Percent-level timing of reionization: self-consistent, implicit-likelihood inference from XQR-30+ Ly forest data
Yuxiang Qin, Andrei Mesinger, David Prelogović +13
The Lyman alpha (Lya) forest in the spectra of z>5 quasars provides a powerful probe of the late stages of the Epoch of Reionization (EoR). With the recent advent of exquisite data…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Supports Earlier Reionization around [OIII] Emitters
Xiangyu Jin, Jinyi Yang, Xiaohui Fan +22
Understanding when and how reionization happened is crucial for studying the early structure formation and the properties of first galaxies in the Universe. At , the observe…
Damping Wing-Like Features in the Stacked Ly Forest: Potential Neutral Hydrogen Islands at
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +28
Recent quasar absorption line observations suggest that reionization may end as late as . As a means to search for large neutral hydrogen islands at , we revisi…
Constraints on the variation of the fine-structure constant at 3<z<10 with JWST emission-line galaxies
Linhua Jiang, Shuqi Fu, Feige Wang +7
We present constraints on the spacetime variation of the fine-structure constant at redshifts using JWST emission-line galaxies. The galaxy sample consists of 62…
Deep Learning the Intergalactic Medium using Lyman-alpha Forest at
Fahad Nasir, Prakash Gaikwad, Frederick B. Davies +3
Unveiling the thermal history of the intergalactic medium (IGM) at holds the potential to reveal early onset HeII reionization or lingering thermal fluctuations f…
Blind QSO reconstruction challenge: Exploring methods to reconstruct the Ly emission line of QSOs
Bradley Greig, Sarah E. I. Bosman, Frederick B. Davies +9
Reconstructing the intrinsic Ly line flux from high- QSOs can place constraints on the neutral hydrogen content of the intergalactic medium during reionisation. There are now…
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…
Photometric IGM tomography with Subaru/HSC: the large-scale structure of Ly emitters and IGM transmission in the COSMOS field at
Koki Kakiichi, Joseph F. Hennawi, Yoshiaki Ono +5
We present a novel technique called "photometric IGM tomography" to map the intergalactic medium (IGM) at in the COSMOS field. It utilizes deep narrow-band (NB) imagin…
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…
