Mergers may not be the main channel for galaxy stellar mass growth at redshift : Predictions from cosmological hierarchical models and simulations
Hao Fu, Mohammadreza Ayromlou, Francesco Shankar +13
Mergers are a crucial channel of galaxy growth, but their role relative to star formation remains uncertain at high redshift. Here we investigate merger rates and merger-driven ste…
Fountain pattern of baryon cycle revealed in galaxy ecosystems
Chengyu Ma, Yangyao Chen, Enci Wang +11
Baryons in galaxy ecosystems are believed to undergo continuous cycles of inflow and outflow, forming fountain-like patterns that encode key information about how galaxies acquire…
Reconstructing the Projected Dark Matter Field across 0.1-100 Mpc Scales from the SDSS Survey
Kunyao Zhao, Yingjie Peng, Dingyi Zhao +16
Dark matter sets the gravitational environment in which galaxies form and evolve, but cannot be observed directly. We present a conditional diffusion model that reconstructs the pr…
Forged in Quenching: Morphological Transformation across Star-forming and Quiescent Galaxies in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +15
The connection between morphology and quenching in central galaxies is well established, but its physical origin remains widely debated. We address this by tracing the main progeni…
No Detectable One-halo Galactic Conformity Signal with Halo-mass Estimates Consistent with Weak-lensing Constraints
Dingyi Zhao, Yingjie Peng, Luis C. Ho +17
One-halo galactic conformity is the tendency for satellites in halos with quenched centrals to have lower star-formation activity than those in halos with star-forming centrals at…
Ruffled Feathers: Merger-driven galaxy size growth and structural transformation in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +9
Galaxy mergers drive both the size growth and the transformation from discs to spheroids, yet the prescriptions used to model these processes in semi-analytic frameworks have not b…
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…
Cooler Phases of the Circumgalactic Medium Are More Centrally Concentrated: Constraints from Multiphase Absorption Lines
Weiwen Kong, Zeyu Chen, Enci Wang +7
We present a systematic study of the multiphase circumgalactic medium (CGM) around galaxies and quasars, traced by Ca II , Mg II , and C IV $λ…
Dissecting the mass quenching in TNG50: Galaxy size determines the quenching mode
Haochen Jiang, Enci Wang, Kai Wang +2
The diminishing of star formation is accompanied by size differentiating, as quiescent galaxies are more compact than star-forming galaxies at fixed stellar mass. In order to under…
Potential-Driven Metal Cycling: JADES Census of Gas-Phase Metallicity for galaxies at 1 < z < 7
Cheng Jia, Enci Wang, Cheqiu Lyu +9
The gravitational potential is established as a critical determinant of gas-phase metallicity (12+log(O/H)) in low-redshift galaxies, whereas its influence remains unconfirmed at h…
The physical origin of positive metallicity radial gradients in high-redshift galaxies: insights from the FIRE-2 cosmological hydrodynamic simulations
Xunda Sun, Xin Wang, Xiangcheng Ma +11
Using the FIRE-2 cosmological zoom-in simulations, we investigate the temporal evolution of gas-phase metallicity radial gradients of Milky Way-mass progenitors in the redshift ran…
From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function
Dingyi Zhao, Yingjie Peng, Yipeng Jing +18
In CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM) t…
From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction
Zeyu Gao, Yingjie Peng, Kai Wang +18
The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional method…
Testing galaxy formation models with the stellar mass-halo mass relations for star-forming and quiescent galaxies
Kai Wang, Yingjie Peng
The tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critic…
Revisiting the fundamental metallicity relation with observation and simulation
Chengyu Ma, Kai Wang, Enci Wang +7
The gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution. Beyond the fundamenta…
From Halos to Galaxies. IX. Estimate of Halo Assembly History for SDSS Galaxy Groups
Cheqiu Lyu, Yingjie Peng, Yipeng Jing +15
The properties of the galaxies are tightly connected to their host halo mass and halo assembly history. Accurate measurement of the halo assembly history in observation is challeng…
Black holes regulate cool gas accretion in massive galaxies
Tao Wang, Ke Xu, Yuxuan Wu +10
The nucleus of almost all massive galaxies contains a supermassive black hole (BH). The feedback from the accretion of these BHs is often considered to have crucial roles in establ…
From Halos to Galaxies. VII. The Connections Between Stellar Mass Growth History, Quenching History and Halo Assembly History for Central Galaxies
Cheqiu Lyu, Yingjie Peng, Yipeng Jing +12
The assembly of galaxies over cosmic time is tightly connected to the assembly of their host dark matter halos. We investigate the stellar mass growth history and the chemical enri…
