The Environmental Dependence of Halo Intrinsic Alignments: Stronger Signals in Underdense Regions
Masaya Ichikawa, Jingjing Shi, Toshiki Kurita +3
The intrinsic alignment (IA) of galaxies and the dark matter haloes that host them is one of the leading astrophysical systematics for weak-lensing cosmology, yet how the IA signal…
IllustrisTNG in the HSC-SSP: image data release and the major role of mini mergers as drivers of asymmetry and star formation
Connor Bottrell, Hassen M. Yesuf, Gergö Popping +13
At fixed galaxy stellar mass, there is a clear observational connection between structural asymmetry and offset from the star forming main sequence, SFMS. Herein, we use the TNG…
The Intrinsic Alignment of Galaxy Clusters and Impact of Projection Effects
Jingjing Shi, Tomomi Sunayama, Toshiki Kurita +7
Galaxy clusters, being the most massive objects in the Universe, exhibit the strongest alignment with the large-scale structure. However, mis-identification of members due to proje…
Alignments Between Galaxies and the Cosmic Web at in the IllustrisTNG Simulations
Benjamin Zhang, Khee-Gan Lee, Alex Krolewski +3
Galaxy formation theories predict that galaxy shapes and angular momenta have non-random alignments with the cosmic web. This leads to so-called intrinsic alignment between pairs o…
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…
A machine learning approach to infer the accreted stellar mass fractions of central galaxies in the TNG100 simulation
Rui Shi, Wenting Wang, Zhaozhou Li +5
We propose a random forest (RF) machine learning approach to determine the accreted stellar mass fractions () of central galaxies, based on various dark matter halo…

Junyao Li, John D. Silverman, Xuheng Ding +11
We measure the evolution of the relation using 584 uniformly-selected SDSS quasars at . The black-hole masses () are derived from the single…
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 (…
An Optimal Estimator of Intrinsic Alignments for Star-forming Galaxies in IllustrisTNG Simulation
Jingjing Shi, Ken Osato, Toshiki Kurita +1
Emission line galaxies (ELGs), more generally star-forming galaxies, are valuable tracers of large-scale structure and therefore main targets of upcoming wide-area spectroscopic ga…
Evaluating the origins of the secondary bias based on the correlation of halo properties with the linear density field
Xiaoyu Wang, Huiyuan Wang, H. J. Mo +2
Using two sets of large -body simulations, we study the origin of the correlations of halo assembly time (), concentration () and spin ()…
The stellar mass in and around isolated central galaxies: connections to the total mass distribution through galaxy-galaxy lensing in the Hyper Suprime-Cam survey
Wenting Wang, Xiangchong Li, Jingjing Shi +7
Using photometric galaxies from the HSC survey, we measure the stellar mass density profiles for satellite galaxies as a function of the projected distance, , to isolated cent…
Hosts and triggers of AGNs in the Local Universe
