The parameter-free Finger-Of-God model and its application to 21cm intensity mapping
Jiajun Zhang, André A. Costa, Bin Wang +3
Using the galaxy catalog built from ELUCID N-body simulation and the semi-analytical galaxy formation model, we have built a mock HI intensity mapping map. We have implemented the…
Simulating the scattering of low-frequency Gravitational Waves by compact objects using the finite element method
Jian-hua He
We investigate the wave effects of gravitational waves (GWs) using numerical simulations with the finite element method (FEM) based on the publicly available code {\it deal.ii}. We…
Modelling the tightest relation between galaxy properties and dark matter halo properties from hydrodynamical simulations of galaxy formation
Jian-hua He
We investigate how a property of a galaxy correlates most tightly with a property of its host dark matter halo, using state-of-the-art hydrodynamical simulations of galaxy formatio…
An accurate method to determine the systematics due to the peculiar velocities of galaxies in measuring the Hubble constant from gravitational wave standard sirens
Jian-hua He
We propose a novel approach to accurately pin down the systematics due to the peculiar velocities of galaxies in measuring the Hubble constant from nearby galaxies in current and f…
A general framework to test gravity using galaxy clusters II: A universal model for the halo concentration in gravity
Myles A. Mitchell, Christian Arnold, Jian-hua He +1
We present a novel fitting formula for the halo concentration enhancement in chameleon gravity relative to General Relativity (GR). The formula is derived by employing a lar…
