Anisotropic quenching beyond and its implications for preprocessing around high-redshift galaxy clusters
Makoto Ando, Kazuhiro Shimasaku, Kei Ito +2
Recent studies have shown that, within galaxy clusters, quenched satellite galaxies tend to be distributed preferentially along the major axis of the central galaxy, dubbed anisotr…
Extended [CII] gas emission in and around a massive quiescent galaxy at z=7.3
F. Valentino, A. Pensabene, A. Weibel +16
We report the discovery of [CII] 158 micron emission in and around the most distant known massive quiescent galaxy RUBIES-UDS-QG-z7 at z = 7.27. Observed with ALMA in band 6, the […
Morphology, sizes, and scatter in a large sample of distant quiescent galaxies
G. Scarpe, F. Valentino, K. Ito +3
After quenching galaxies keep growing in size across time, as established in the literature up to cosmic noon. In this work, we assemble one of the largest and most comprehensive m…
Chemical signatures from the first stars embedded in metal-poor gas in galaxies at cosmic dawn
Clara L. Pollock, Kasper E. Heintz, Elka Rusta +15
The first generation of stars formed from pristine, neutral hydrogen gas. The most massive of these exploded as supernovae within a few million years of their birth, producing the…
Unveiling the population of massive quenched galaxies at in the COLIBRE simulations -- II. The role of AGN feedback and environment on their emergence
Ãngel Chandro-Gómez, Claudia del P. Lagos, Chris Power +16
Early () Massive (), Quenched Galaxies (MQGs) challenge current galaxy formation models. In this series, we study these…
Subaru High- Exploration of Low-Luminosity Quasars (SHELLQs). XXV. Large-scale environments of low-luminosity quasars at traced by Ly emitters
Junya Arita, Nobunari Kashikawa, Yoshiki Matsuoka +18
High- quasars are believed to reside in massive dark matter haloes (DMHs), suggesting that they reside in galaxy overdense regions. However, previous observations have shown a r…
