Modelling the mass accretion histories of dark matter haloes using a Gamma formalism
Antonios Katsianis, Xiaohu Yang, Matthew Fong +1
We present a physical model of the Mass Accretion Histories (MAH) of haloes in concordance with the {\it observed} cosmic star formation rate density (CSFRD). We model the MAHs of…
Physical evolution of dark matter halo around the depletion boundary
Hongyu Gao, Jiaxin Han, Matthew Fong +2
We investigate the build-up of the halo profile out to large scale in a cosmological simulation, focusing on the roles played by the recently proposed depletion radii. We explicitl…
Halo Properties and Mass Functions of Groups/Clusters from the DESI Legacy Imaging Surveys DR9
Jiaqi Wang, Xiaohu Yang, Jun Zhang +16
Based on a large group/cluster catalog recently constructed from the DESI Legacy Imaging Surveys DR9 using an extended halo-based group finder, we measure and model the group-galax…
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…
A natural boundary of dark matter haloes revealed around the minimum bias and maximum infall locations
Matthew Fong, Jiaxin Han
We explore the boundary of dark matter haloes through their bias and velocity profiles. Using cosmological -body simulations, we show that the bias profile exhibits a ubiquitous…
The impact of baryonic physics and massive neutrinos on weak lensing peak statistics
Matthew Fong, Miyoung Choi, Victoria Catlett +5
We study the impact of baryonic processes and massive neutrinos on weak lensing peak statistics that can be used to constrain cosmological parameters. We use the BAHAMAS suite of c…
Prospects for Determining the Mass Distributions of Galaxy Clusters on Large Scales Using Weak Gravitational Lensing
M. Fong, R. Bowyer, A. Whitehead +4
For more than two decades, the Navarro, Frenk, and White (NFW) model has stood the test of time; it has been used to describe the distribution of mass in galaxy clusters out to the…
