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
The paper uses FAST and DESI data to stack HI spectra of galaxies in 36 nearby clusters, showing that neutral hydrogen content is already depleted out to five times the virial radi…
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…
