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…
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…
Clumpy Starburst in a Local Dwarf Galaxy, NGC 1522
Liuze Long, Yulong Gao, Qiusheng Gu +8
To investigate the star-forming process in nearby dwarf galaxies, we present Integral Field Units (IFU) observation of the star-forming dwarf galaxy, NGC 1522, with the Very Large…
The critical role of dark matter halos in driving star formation
Jing Dou, Yingjie Peng, Qiusheng Gu +13
Understanding the physical mechanisms that drive star formation is crucial for advancing our knowledge of galaxy evolution. We explore the interrelationships between key galaxy pro…
The HI reservoir in central spiral galaxies and the implied star formation process
Jing Dou, Yingjie Peng, Qiusheng Gu +14
The cold interstellar medium (ISM) as the raw material for star formation is critical to understanding galaxy evolution. It is generally understood that galaxies stop making stars…
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…
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…
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…
Merger-induced star formation in low-metallicity dwarf galaxy NGC 4809/4810
Yulong Gao, Qiusheng Gu, Guilin Liu +5
The physical mechanisms driving starbursts in dwarf galaxies are unclear, and the effects of mergers on star formation in these galaxies are still uncertain. We explore how the mer…
Cold Gas in Massive Galaxies as A Critical Test of Black Hole Feedback Models
Jingjing Shi, Yingjie Peng, Benedikt Diemer +15
Black hole feedback has been widely implemented as the key recipe to quench star formation in massive galaxies in modern semi-analytic models and hydrodynamical simulations. As the…
From haloes to galaxies. III. The gas cycle of local galaxy populations
Jing Dou, Yingjie Peng, Alvio Renzini +12
In Dou et al. (2021), we introduced the Fundamental Formation Relation (FFR), a tight relation between specific SFR (sSFR), H star formation efficiency (SFE), and t…
Mass and Environment as Drivers of Galaxy Evolution. IV. On the Quenching of Massive Central Disk Galaxies in The Local Universe
Chengpeng Zhang, Yingjie Peng, Luis C. Ho +13
The phenomenological study of evolving galaxy populations has shown that star forming galaxies can be quenched by two distinct processes: mass quenching and environment quenching (…
From haloes to galaxies -- II. The fundamental relations in star formation and quenching
Jing Dou, Yingjie Peng, Alvio Renzini +10
Star formation and quenching are two of the most important processes in galaxy formation and evolution. We explore in the local Universe the interrelationships among key integrated…
Nearly all Massive Quiescent Disk Galaxies have a Surprisingly Large Atomic Gas Reservoir
Chengpeng Zhang, Yingjie Peng, Luis C. Ho +11
The massive galaxy population above the characteristic Schechter mass M*~10^10.6 Msun contributes to about half of the total stellar mass in the local Universe. These massive galax…
The Fundamental Relation between Halo Mass and Galaxy Group Properties
Zhong-yi Man, Ying-jie Peng, Jing-jing Shi +4
We explore the interrelationships between the galaxy group halo mass and various observable group properties. We propose a simple scenario that describes the evolution of the centr…
The Dependence of AGN Activity on Environment in SDSS
Zhong-yi Man, Ying-jie Peng, Xu Kong +3
Environment is one of the key external drivers of the galaxies, while active galactic nucleus (AGN) is one of the key internal drivers. Both of them play fundamental roles in regul…
SDSS-IV MaNGA: The Roles of AGNs and Dynamical Processes in Star Formation Quenching in Nearby Disk Galaxies
Kexin Guo, Yingjie Peng, Li Shao +7
We study how star formation (SF) is quenched in low-redshift disk galaxies with integral-field spectroscopy. We select 131 face-on spiral galaxies with stellar mass greater than $\…
