HI Depletion Begins Well Beyond the Virial Radius: A FAST Stacking Study of 36 Galaxy Clusters to 5R200
Cheng Cheng, Chuan-Peng Zhang, Edo Ibar +10
We present a stacking study of the neutral atomic hydrogen (HI) content in and around 36 local galaxy clusters at , using a combination of the FAST all sky HI survey (FASHI…
Multiwavelength Analysis of PSR J0437-4715 with Pulse Profile Modeling
Liqiang Qi, Juan Zhang, Weiwei Xu +6
We present a multi-wavelength analysis of the nearby millisecond pulsar PSR J0437--4715, combining Hubble Space Telescope (HST) far-ultraviolet, ROSAT soft X-ray, and XMM-Newton X-…
Mock Observations for the CSST Mission: Multi-Channel Imager--The Cluster Field
Yushan Xie, Xiaokai Chen, Shuai Feng +20
The Multi-Channel Imager (MCI), one of the instruments aboard the China Survey Space Telescope (CSST), is designed to simultaneously observe the sky in three filters, covering wave…
A Comparative Study of Halo Mass Estimates from Group Catalogs and Lensing Signals
Xinyue Chen, Weiwei Xu, Ran Li +3
We compare halo mass estimates from three galaxy group catalogs (redMaPPer, Yang21, and Zou21) with those derived from gravitational lensing measurements. Each catalog employs dist…
The measurement of the splashback radius of dark matter halo
Weiwei Xu, Huanyuan Shan, Ran Li +4
In the hierarchical evolution framework of cosmology, larger halos grow through matter accretion and halo mergers. To clarify the halo evolution, we need to define the halo mass an…
Assessing Mass Loss and Stellar-to-Halo Mass Ratio of Satellite Galaxies: A Galaxy-Galaxy Lensing Approach Utilizing DECaLS DR8 Data
Chunxiang Wang, Ran Li, Huanyuan Shan +9
The galaxy-galaxy lensing technique allows us to measure the subhalo mass of satellite galaxies, studying their mass loss and evolution within galaxy clusters and providing direct…
MaNGA DynPop -- IV. Stacked total density profile of galaxy groups and clusters from combining dynamical models of integral-field stellar kinematics and galaxy-galaxy lensing
Chunxiang Wang, Ran Li, Kai Zhu +9
We present the measurement of total and stellar/dark matter decomposed mass density profile around a sample of galaxy groups and clusters with dynamical masses derived from integra…
Spectroscopic Confirmation of Two X-ray Diffuse and Massive Galaxy Clusters at Low Redshift
Kaiyuan Chen, Weiwei Xu, Linhua Jiang
We present MMT spectroscopic observations of two massive galaxy cluster candidates at redshift that show extended and diffuse X-ray emission in the ROSAT All Sky Survey…
Halo Mass-Concentration Relation at High-Mass End
Weiwei Xu, Huanyuan Shan, Ran Li +6
The concentration-mass (c-M) relation encodes the key information of the assembly history of the dark matter halos, however its behavior at the high mass end has not been measured…
Ram pressure stripping of HI-rich galaxies infalling into massive clusters
Jing Wang, Weiwei Xu, Bumhyun Lee +3
We estimate the strength of ram pressure stripping (RPS) for HI-rich galaxies in X-ray detected clusters. We find that galaxies under stronger RPS tend to show more significantly r…
