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 Little Red Dot at within a Large Galaxy Overdensity
Jan-Torge Schindler, Joseph F. Hennawi, Frederick B. Davies +11
The nature of "Little Red Dots" and their relation to other forms of accreting supermassive black holes remain an open question. Here we report the discovery of a Little Red Dot at…
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…
A Quasar-Anchored Protocluster at z=6.6 in the ASPIRE Survey: II. An Environmental Analysis of Galaxy Properties in an Overdense Structure
Jaclyn B. Champagne, Feige Wang, Jinyi Yang +21
We present paper II comprising a 35 arcmin \textit{JWST}/NIRCam imaging and wide-field slitless spectroscopy mosaic centered on J03053150, a luminous quasar at . The…
A Quasar-Anchored Protocluster at z=6.6 in the ASPIRE Survey: I. Properties of [OIII] Emitters in a 10 Mpc Overdensity Structure
Jaclyn B. Champagne, Feige Wang, Haowen Zhang +25
ASPIRE (A SPectroscopic survey of bIased halos in the Reionization Era) is a quasar legacy survey primarily using \textit{JWST} to target a sample of 25 quasars with NIRCam s…
No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time
Danyang Jiang, Masafusa Onoue, Linhua Jiang +13
The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expect…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
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…
MIDIS: MIRI uncovers Virgil, the first Little Red Dot with clear detection of its host galaxy at z ~ 6.6
Edoardo Iani, Pierluigi Rinaldi, Karina I. Caputi +24
We present Virgil, a MIRI extremely red object (MERO) detected with the F1000W filter as part of the MIRI Deep Imaging Survey (MIDIS) observations of the Hubble Ultra Deep Field (H…
