JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS

Romain A. Meyer, Feige Wang, Koki Kakiichi +38

We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 Ã Luminosity Function (LF) in the COSMOS field. We leverage the…

An extremely metal-poor Lyman emitter candidate at revealed through absorption spectroscopy

Dominika Ďurovčíková, Anna-Christina Eilers, Robert A. Simcoe +10

We report the discovery of a Lyman emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at at a projected distance $\sim29\ {\rm…

Chronicling the reionization history at with emergent quasar damping wings

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

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

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…

Robustness of direct measurements of the mean free path of ionizing photons in the epoch of reionization

Sindhu Satyavolu, Girish Kulkarni, Laura C. Keating +1

Measurements of the mean free path of Lyman-continuum photons in the intergalactic medium during the epoch of reionization can help constrain the nature of the sources as well as s…
