Gas Density Profile in Dark Matter Halo in Chameleon Cosmology
Gas Density Profile in Dark Matter Halo in Chameleon Cosmology
We investigate the gas density, temperature, and pressure profiles in a dark matter halo under the influence of the chameleon force. We solve the hydrostatic equilibrium equation for the gas coupled with the chameleon field in an analytic manner, using an approximate solution for the chameleon field equation with the …
