This week’s entry discusses the effects of the Hubble constant on the growth of high-redshift supermassive black holes, a new test of General Relativity from galaxy-galaxy lensing and clustering amplitudes, and a new WIMP dark matter production mechanism from conformal or disformal couplings to ultra-light scalars.
