An HSC view of the CMASS galaxy sample. Halo mass as a function of stellar mass, size and Sérsic index
Alessandro Sonnenfeld, Wenting Wang, Neta Bahcall
Aims. We wish to determine the distribution of dark matter halo masses as a function of the stellar mass and the stellar mass profile, for massive galaxies in the BOSS CMASS sample…
The stellar halo of isolated central galaxies in the Hyper Suprime-Cam imaging survey
Wenting Wang, Jiaxin Han, Alessandro Sonnenfeld +14
We study the faint stellar halo of isolated central galaxies, by stacking galaxy images in the HSC survey and accounting for the residual sky background sampled with random points.…
The mass of the Milky Way from satellite dynamics
Thomas Callingham, Marius Cautun, Alis J. Deason +6
We present and apply a method to infer the mass of the Milky Way (MW) by comparing the dynamics of MW satellites to those of model satellites in the EAGLE cosmological hydrodynamic…
The multidimensional dependence of halo bias in the eye of a machine: a tale of halo structure, assembly and environment
Jiaxin Han, Yin Li, Yipeng Jing +3
We develop a novel approach in exploring the joint dependence of halo bias on multiple halo properties using Gaussian process regression. Using a CDM -body simulation, we car…
What to expect from dynamical modelling of galactic haloes II: the spherical Jeans equation
Wenting Wang, Jiaxin Han, Shaun Cole +3
The spherical Jeans equation (SJE) is widely used in dynamical modelling of the Milky Way (MW) halo potential. We use haloes and galaxies from the cosmological Millennium-II simula…
