SDSS-IV MaNGA: A Distinct Mass Distribution Explored in Slow-Rotating Early-type Galaxies
Yu Rong, Hongyu Li, Jie Wang +8
We study the radial acceleration relation (RAR) for early-type galaxies (ETGs) in the SDSS MaNGA MPL5 dataset. The complete ETG sample show a slightly offset RAR from the relation…
Gas contents of galaxy groups from thermal Sunyaev-Zel'dovich effects
Seunghwan Lim, Houjun Mo, Ran Li +4
A matched filter technique is applied to the Planck all-sky Compton y-parameter map to measure the thermal Sunyaev-Zel'dovich (tSZ) effect produced by galaxy groups of different ha…
Resolution of the apparent discrepancy between the number of massive subhaloes in Abell 2744 and ΛCDM
Tian-Xiang Mao, Jie Wang, Carlos S. Frenk +5
Schwinn et al. (2017) have recently compared the abundance and distribution of massive substructures identified in a gravitational lensing analysis of Abell 2744 by Jauzac et al. (…
Globular clusters vs dark matter haloes in strong lensing observations
Qiuhan He, Ran Li, Sungsoon Lim +4
Small distortions in the images of Einstein rings or giant arcs offer the exciting prospect of detecting dark matter haloes or subhaloes of mass below M, most of wh…
Baryon effects on the dark matter halos constrained from strong gravitational lensing
Lin Wang, Da-Ming Chen, Ran Li
Simulations are expected to be the powerful tool to investigate the baryon effects on dark matter (DM) halos. Recent high resolution, cosmological hydrodynamic simulations (\citeal…
SDSS J1640+1932: a spectacular galaxy-quasar strong lens system
Lin Wang, Yiping Shu, Ran Li +3
We present Canada-France-Hawaii Telescope (CFHT) MegaCam observations of a galaxy-quasar strong gravitational lens system, SDSS J1640+1932. This system, located at z=0.195 (foregro…
