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.…
Using the Modified Nearest Neighbor Method to Correct Fiber-collision Effects on Galaxy Clustering
Lei Yang, Yipeng Jing, Xiaohu Yang +1
Fiber collision is a persistent problem faced by modern spectroscopic galaxy surveys. In this work, we propose a new method to correct for this undesired effect, focusing on the cl…
Constraining Dark Energy With Stacked Concave Lenses
Fuyu Dong, Jun Zhang, Yu Yu +6
Low density regions are less affected by the nonlinear structure formation and baryonic physics. They are ideal places for probing the nature of dark energy, a possible explanation…
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…
