Cluster gas fraction as a test of gravity
Baojiu Li, Jian-hua He, Liang Gao
We propose a new cosmological test of gravity, by using the observed mass fraction of X-ray emitting gas in massive galaxy clusters. The cluster gas fraction, believed to be a fair…
An accurate method of modeling cluster scaling relations in modified gravity
Jian-hua He, Baojiu Li
We propose a new method to model cluster scaling relations in modified gravity. Using a suite of non-radiative hydrodynamical simulations, we show that the scaling relations of cum…
Effective dark matter power spectra in gravity
Jian-hua He, Baojiu Li, Adam J. Hawken
Using N-body simulations, we measure the power spectrum of the effective dark matter density field, which is defined through the modified Poisson equation in cosmologies. We…
Effective Dark Matter Halo catalog in gravity
Jian-hua He, Adam J. Hawken, Baojiu Li +1
We introduce the idea of {\it effective} dark matter halo catalog in gravity, which is built using the {\it effective} density field. Using a suite of high resolution N-body…
