Satellite quenching by radio jets of central galaxies in galaxy groups
Yijun Wang, Tao Wang, Dingyi Zhao +9
Feedback from active galactic nuclei (AGN) is now recognized as a key component of galaxy formation models. It plays a central role in regulating the growth and quenching of galaxi…
Radio AGN feedback sustains quiescence only in a minority of massive galaxies
Huiling Liu, Yan Lu, Hui Hong +11
Radio active galactic nuclei (AGNs) eject a huge amount of energy into the surrounding medium and are thought to potentially prevent gas cooling and maintain the quiescence of mass…
Unexpected clustering pattern in dwarf galaxies challenges formation models
Ziwen Zhang, Yangyao Chen, Yu Rong +4
The galaxy correlation function serves as a fundamental tool for studying cosmology, galaxy formation, and the nature of dark matter. It is well established that more massive, redd…
Measuring Mass of Gas in Central Galaxies using weak lensing and satellite kinematics in MOND
Li Ma, Ziwen Zhang, Huiyuan Wang +1
In Milgrom's modified Newtonian dynamics (MOND) framework, the dynamical mass of a galaxy is fully determined by its baryonic matter distribution. We fit the distribution of cold a…
UNIONS: a direct measurement of intrinsic alignment with BOSS/eBOSS spectroscopy
Fabian Hervas Peters, Martin Kilbinger, Romain Paviot +12
During their formation, galaxies are subject to tidal forces, which create correlations between their shapes and the large-scale structure of the Universe, known as intrinsic align…
