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…
MaNGA DynPop -- VI. Matter density slopes from dynamical models of 6000 galaxies versus cosmological simulations: the interplay between baryonic and dark matter
Shubo Li, Ran Li, Kai Zhu +5
We try to understand the trends in the mass density slopes as a function of galaxy properties. We use the results from the best Jeans Anisotropic Modelling (JAM) of the integral-fi…
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…
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…
ALMA [N ıı] 205 μm Imaging Spectroscopy of the Lensed Submillimeter galaxy ID 141 at redshift 4.24
Cheng Cheng, Xiaoyue Cao, Nanyao Lu +17
We present the Atacama Large Millimeter/submillimeter Array (ALMA) observation of the Sub-millimeter galaxy (SMG) ID 141 at z=4.24 in the [N II] 205 m line (hereafter [N II]) an…
SDSS--IV MaNGA : The Inner Density Slopes of nearby galaxies
Ran Li, Hongyu Li, Shi Shao +12
We derive the mass weighted total density slopes within the effective (half-light) radius, , for more than 2000 nearby galaxies from the SDSS-IV MaNGA survey using Jeans-anisot…
Dark-matter-deficient galaxies in hydrodynamical simulations
Yingjie Jing, Chunxiang Wang, Ran Li +4
Low mass galaxies are expected to be dark matter dominated even within their centrals. Recently two observations reported two dwarf galaxies in group environment with very little d…
Do satellite galaxies trace matter in galaxy clusters?
Chunxiang Wang, Ran Li, Liang Gao +9
The spatial distribution of satellite galaxies encodes rich information of the structure and assembly history of galaxy clusters. In this paper, we select a redMaPPer cluster sampl…
On frequency dependence of pulsar linear polarization
P. F. Wang, C. Wang, J. L. Han
Frequency dependence of pulsar linear polarization is investigated by simulations of emission and propagation processes. Linearly polarized waves are generated through curvature ra…
Polarized Curvature Radiation in Pulsar Magnetosphere
P. F. Wang, C. Wang, J. L. Han
The propagation of polarized emission in pulsar magnetosphere is investigated in this paper. The polarized waves are generated through curvature radiation from the relativistic par…
