PAC in DESI. II. Galaxy-halo connection into the frontier
Kun Xu, Carlos S. Frenk, Y. P. Jing +37
Understanding dwarf galaxy formation is crucial for testing dark matter models and reionization physics. However, constructing stellar-mass complete spectroscopic samples at low ma…
Describing the Nonuniversal Galaxy Merger Timescales in IllustrisTNG: Effects of Host Halo Mass, Baryons, and Sample Selection
Kun Xu, Y. P. Jing
Galaxy merger timescales are crucial for understanding and modeling galaxy formation in our hierarchically structured Universe. However, previous studies have reported widely varyi…
Photometric Objects Around Cosmic Webs (PAC). VII. Disentangling Mass and Environment Quenching with the Aid of Galaxy-halo Connection in Simulations
Yun Zheng, Kun Xu, Donghai Zhao +4
Star formation quenching in galaxies is a critical process in galaxy formation. It is widely believed that the quenching process is dominated by the mass of galaxies and/or their e…
Deep extragalactic HI survey of the COSMOS field with FAST
Hengxing Pan, Matt J. Jarvis, Ming Zhu +9
We present a deep HI survey at L-band conducted with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) over the COSMOS field. This survey is strategically designed t…
PAC.V. The Roles of Mass and Environment in the Quenching of Galaxies
Yun Zheng, Kun Xu, Y. P. Jing +6
The roles that mass and environment play in the galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs (PAC) method, we analyze the excess s…
Photometric Objects Around Cosmic Webs (PAC). VI. High Satellite Fraction of Quasars
Shanquan Gui, Kun Xu, Y. P. Jing +2
The Photometric objects Around Cosmic webs (PAC) approach developed in Xu et al. (2022b) has the advantage of making full use of spectroscopic and deeper photometric surveys. With…
Toward a Physical Understanding of Galaxy-Halo Alignment
Kun Xu, Y. P. Jing, Donghai Zhao
We investigate the alignment of galaxy and halo orientations using the TNG300-1 hydrodynamical simulation. Our analysis reveals that the distribution of the 2D misalignment angle $…
Photometric Objects Around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. IV. High Precision Constraints on the Evolution of Stellar-Halo Mass Relation at Redshift
Kun Xu, Y. P. Jing, Yun Zheng +1
Taking advantage of the Photometric objects Around Cosmic webs (PAC) method developed in Paper I, we measure the excess surface density of photometric objects…
Construct the emission line galaxy-host halo connection through auto and cross correlations
Hongyu Gao, Y. P. Jing, Yun Zheng +1
We investigate the [O\,II] emission line galaxy (ELG)-host halo connection via auto and cross correlations, and propose a concise and effective method to populate ELGs in dark matt…
A Versatile and Accurate Method for Halo Mass Determination from Phase-Space Distribution of Satellite Galaxies
Zhao-Zhou Li, Yong-Zhong Qian, Jiaxin Han +2
We propose a versatile and accurate method to estimate the halo mass and concentration from the kinematics of satellite galaxies. We construct the 6D phase-space distribution funct…
ELUCID V. Lighting dark matter halos with galaxies
Xiaohu Yang, Youcai Zhang, Huiyuan Wang +16
In a recent study, using the distribution of galaxies in the north galactic pole of SDSS DR7 region enclosed in a 500$\mpch$ box, we carried out our ELUCID simulation (Wang et al.…
Constraining the HI-Halo Mass Relation From Galaxy Clustering
Hong Guo, Cheng Li, Zheng Zheng +5
We study the dependence of galaxy clustering on atomic gas mass using a sample of 16,000 galaxies with redshift in the range of and HI mass of $M_{\rm HI}>10^…
