Effects of Active Galactic Nucleus Feedback on Cold Gas Depletion and Quenching of Central Galaxies
Wenlin Ma, Kexin Liu, Hong Guo +5
We investigate the influence of active galactic nucleus (AGN) feedback on the galaxy cold gas content and its connection to galaxy quenching in three hydrodynamical simulations of…
Galaxy-halo size relation from Sloan Digital Sky Survey Data Release 7 and the ELUCID simulation
Youcai Zhang, Xiaohu Yang, Hong Guo
Based on galaxies in the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) and dark matter haloes in the dark matter only, cosmological and constrained ELUCID simulation, we inves…
Theoretical Models of the Atomic Hydrogen Content in Dark Matter Halos
Zhixing Li, Hong Guo, Yi Mao
Atomic hydrogen (H I) gas, mostly residing in dark matter halos after cosmic reionization, is the fuel for star formation. Its relation with properties of host halo is the key to u…
SDSS-IV MaNGA: Global Properties of Kinematically Misaligned Galaxies
Yuren Zhou, Yanmei Chen, Yong Shi +6
We select 456 gas-star kinematically misaligned galaxies from the internal Product Launch-10 of MaNGA survey, including 74 star-forming (SF), 136 green-valley (GV) and 206 quiescen…
Cold Gas Reservoirs of Low- and High-mass Central Galaxies Differ in Response to Active Galactic Nucleus Feedback
Hong Guo, Michael G. Jones, Jing Wang
The growth of supermassive black holes, especially the associated state of active galactic nuclei (AGNs), is generally believed to be the key step in regulating star formation in m…
Evidence of Galaxy Assembly Bias in SDSS DR7 Galaxy Samples from Count Statistics
Kuan Wang, Yao-Yuan Mao, Andrew R. Zentner +4
We present observational constraints on the galaxy-halo connection, focusing particularly on galaxy assembly bias, from a novel combination of counts-in-cylinders statistics, $P(N_…
The Aemulus Project V: Cosmological constraint from small-scale clustering of BOSS galaxies
Zhongxu Zhai, Jeremy L. Tinker, Arka Banerjee +6
We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics. We focus on the monopole and quadrupole of the redshift-space correla…
A Pair of Early- and Late-Forming Galaxy Cluster Samples: a Novel Way of Studying Halo Assembly Bias Assisted by a Constrained Simulation
Yen-Ting Lin, Hironao Miyatake, Hong Guo +4
The halo assembly bias, a phenomenon referring to dependencies of the large-scale bias of a dark matter halo other than its mass, is a fundamental property of the standard cosmolog…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
