Groups and protocluster candidates in the CLAUDS and HSC-SSP joint deep surveys
Qingyang Li, Xiaohu Yang, Chengze Liu +16
Using the extended halo-based group finder developed by Yang et al. (2021), which is able to deal with galaxies via spectroscopic and photometric redshifts simultaneously, we const…
The Universal Specific Merger Rate of Dark Matter Halos
Fuyu Dong, Donghai Zhao, Jiaxin Han +3
We employ a set of high resolution N-body simulations to study the merger rate of dark matter halos. We define a specific merger rate by normalizing the average number of mergers p…
Strong Conformity and Assembly Bias: Towards a Physical Understanding of the Galaxy-Halo Connection in SDSS Clusters
Ying Zu, Yunjia Song, Zhiwei Shao +6
Understanding the physical connection between cluster galaxies and massive haloes is key to mitigating systematic uncertainties in next-generation cluster cosmology. We develop a n…
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 ()…
An Accurate PM Algorithm for Gravitational Lensing Studies in Simulations
Kun Xu, Yipeng Jing
We present a two-dimensional (2D) Particle-Particle-Particle-Mesh (PM) algorithm with an optimized Green function and adaptive softening length for gravitational lensing studie…
Elucidating Galaxy Assembly Bias in SDSS
Andrés N. Salcedo, Ying Zu, Youcai Zhang +6
We investigate the level of galaxy assembly bias in the Sloan Digital Sky Survey (SDSS) main galaxy sample using ELUCID, a state-of-the-art constrained simulation that accurately r…
