Inflow-driven galaxy evolution - I. Revealing the physics of the fundamental metallicity relation
Kai Wang, Carlton Baugh, N. F. Boardman +11
We present a unified physical framework for the fundamental metallicity relation (FMR), based on the mass-continuity equations. The FMR is not merely the anti-correlation between s…
Observational Evidence for Anisotropic Metal Excess around Galaxies
Cheqiu Lyu, Enci Wang, Zeyu Chen +4
The exchange of matter and energy between galaxies and their surroundings drives the cosmic baryon cycle, yet mapping metal transport remains an observational challenge. While simu…
Star formation powers optical line emission from the CGM
Huanian Zhang, Lizhi Xie, Zhijie Qu +9
Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line…
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…
Warped Disk Galaxies: Alignment with the Large-Scale Tidal Field
Yiheng Wang, Huiyuan Wang, Enci Wang +1
A possible origin of disk galaxy warps is the misalignment between galactic disks and their host dark matter halos, the orientations of which are found to be statistically aligned…
Stellar feedback drives the baryon deficiency in low-mass galaxies
Haoran Yu, Enci Wang, Zeyu Chen +8
Stellar feedback, as a key process regulating the baryon cycle, is thought to greatly redistribute baryonic material inside and outside the dark matter halos (DMHs), however the ob…
