Where Do Quasars Live? DESI DR1 Constraints from PAC Measurements
Shanquan Gui, Kun Xu, Donghai Zhao
Quasar environments connect the growth of supermassive black holes, active galactic nucleus feedback, and galaxy evolution. Small-scale quasar clustering probes the one-halo regime…
Antarctic TianMu Staring Observation Project I: Overview and Implementation of the Prototype Telescope
Dan Zhou, Jing Zhong, Jianchun Shi +31
Wide-field rapid sky surveys serve as critical observational methods for time-domain astronomical research. The Antarctic region, with several months of continuous dark nights annu…
Photometric Objects Around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. VIII. Revisiting the Lensing is Low Effect
Xiaolin Luo, Kun Xu, Yipeng Jing +6
The issue of over-predicting the galaxy-galaxy lensing (GGL) signal using conventional galaxy-halo connection models has become well-known as the ``Lensing is Low'' problem, which…
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…
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…
The DESI One-Percent Survey: A concise model for galactic conformity of ELGs
Hongyu Gao, Y. P. Jing, Kun Xu +27
Galactic conformity is the phenomenon in which a galaxy of a certain physical property is correlated with its neighbors of the same property, implying a possible causal relationshi…
The DESI One-Percent survey: constructing galaxy-halo connections for ELGs and LRGs using auto and cross correlations
Hongyu Gao, Y. P. Jing, Shanquan Gui +31
In the current Dark Energy Spectroscopic Instrument (DESI) survey, emission line galaxies (ELGs) and luminous red galaxies (LRGs) are essential for mapping the dark matter distribu…
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 $…
