Is the core-cusp problem a matter of perspective: Jeans Anisotropic Modeling against numerical simulations
Wenting Wang, Ling Zhu, Zhaozhou Li +14
Mock member stars for 28 dwarf galaxies are constructed from the cosmological Auriga simulation, which reflect the dynamical status of realistic stellar tracers. The axis-symmetric…
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…
First measurement of the characteristic depletion radius of dark matter haloes from weak lensing
Matthew Fong, Jiaxin Han, Jun Zhang +6
We use weak lensing observations to make the first measurement of the characteristic depletion radius, one of the three radii that characterize the region where matter is being dep…
Mining the information content of member galaxies in the halo mass modelling
Yanrui Zhou, Jiaxin Han
Motivated by previous findings that the magnitude gap between certain satellite galaxy and the central galaxy can be used to improve the estimation of halo mass, we carry out a sys…
What to expect from dynamical modelling of cluster haloes II. Investigating dynamical state indicators with Random Forest
Qingyang Li, Jiaxin Han, Wenting Wang +5
We investigate the importances of various dynamical features in predicting the dynamical state (DS) of galaxy clusters, based on the Random Forest (RF) machine learning approach. W…
