CLASH-VLT: Constraining deviation from GR with the mass profiles of nine massive galaxy clusters
L. Pizzuti, A. Biviano, K. Umetsu +5
We investigate the anisotropic stress parameter, , defined as the ratio of the gravitational potentials in the linearly perturbed Friedmann-Lemaître Robertson-Walker metric,…

Infalling ultra-faint dwarfs as emissaries of the Axiverse
A. Pozo, T. Broadhurst, H. N. Luu +8
Recent discoveries of ultra-faint dwarf galaxies (UFDs) infalling onto the Milky Way, namely Leo K \& M at kpc, considerably strengthens the case that UFDs constitute…

Using a minimally parametrised SHAM to constrain the link between dark matter and galaxies
F. L. Davidson, D. Bacon, A. Amara +6
Models of the galaxy-halo connection are needed to understand both galaxy clusters and large scale structure. To make said models, we need a robust method that assigns galaxies to…
