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 future gravitational-wave (GW) standard-siren experiments. Given the pr... Read More about Accurate method to determine the systematics due to the peculiar velocities of galaxies in measuring the Hubble constant from gravitational-wave standard sirens.

We present a novel fitting formula for the halo concentration enhancement in chameleon f(R) gravity relative to General Relativity (GR). The formula is derived by employing a large set of N-body simulations of the Hu-Sawicki f(R) model which cover a...
