Even central galaxies feel their environment: cosmic siphoning of cool gas accretion
Ke Xu, Tao Wang
The paper investigates how the environment of central galaxies influences their cool gas accretion, proposing a multi‑scale “cosmic siphoning” process where massive halos and centr…
Environmental Imprints on the Assembly of the Cool Gas around Bright Cluster Galaxies
Runyu Zhu, Hu Zou, Taotao Fang +14
The paper statistically maps cool gas around massive brightest cluster galaxies at z≈0.55 using Mg II absorption from stacked DESI quasar spectra, finding suppressed circumgalactic…
When vacuum breaks: a self-consistency test for astrophysical environments in extreme mass ratio inspirals
Lorenzo Copparoni, Rohit S. Chandramouli, Enrico Barausse
The paper introduces a non‑parametric self‑consistency test that checks whether gravitational‑wave parameter estimates from different parts of an extreme mass ratio inspiral signal…
Mass--size evolution and the emerging passive--density relation revealed by JWST/NIRCam in the Spiderweb protocluster
J. Nadolny, J. M. Pérez-MartÃnez, H. Dannerbauer +8
The paper uses JWST/NIRCam imaging to study how galaxy sizes and structures in the Spiderweb protocluster at z=2.16 depend on environment, finding distinct mass‑size relations for…
An HI+radio continuum study of local cluster galaxies: Intercepting the early stages of environmental processing with MeerKAT
Alessandro Ignesti, Paolo Serra, Alessandro Bianchetti +14
The study uses MeerKAT HI 21 cm and 1.4 GHz radio continuum data to examine galaxies in three nearby clusters, revealing that early-stage environmental processing boosts star forma…
