Strong Stellar Diffusion from Wave DM Cosmological Simulation and Potential Unified Origin for dSphs, UFGs, and UDGs
A. Pozo, T. Broadhurst, J. Zhang +6
Our DM simulations predict that stars diffuse throughout dark matter halos over the Hubble time through a random walk driven by the wave perturbations intrinsic to DM. The re…
CHEX-MATE: AMALGAM weak-lensing analysis of 41 Planck Sunyaev-Zel'dovich-selected galaxy clusters
Keiichi Umetsu, Raphael Gavazzi, Mauro Sereno +20
We present a weak-lensing shear analysis of 41 Planck SZ-selected galaxy clusters at from the CHEX-MATE sample, using wide-field Subaru/Suprime-Cam and CFHT/Meg…
CLASH-VLT: The Fifth Force in Chameleon Gravity from Joint Lensing and Kinematics Cluster Mass Profiles
Lorenzo Pizzuti, Federico Rivano, Keiichi Umetsu +1
We present a high-precision joint gravitational-lensing and kinematic analysis of nine massive galaxy clusters from the CLASH and CLASH-VLT surveys to test chameleon screening grav…
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…
Exploring the stellar populations of backsplash galaxies
Ignacio Ferreras, Asmus Böhm, Keiichi Umetsu +2
Backsplash galaxies are those that traverse and overshoot cluster cores as they fall into these structures. They are affected by environment, and should stand out in contrast to th…
CLASH-VLT: The stellar mass function and stellar mass density profile of the z=0.44 cluster of galaxies MACS J1206.2-0847
M. Annunziatella, A. Biviano, A. Mercurio +29
Context. The study of the galaxy stellar mass function (SMF) in relation to the galaxy environment and the stellar mass density profile, rho(r), is a powerful tool to constrain mod…
Galaxy Cluster Scaling Relations between Bolocam Sunyaev-Zel'dovich Effect and Chandra X-ray Measurements
N. G. Czakon, J. Sayers, A. Mantz +11
We present scaling relations between the integrated Sunyaev-Zel'dovich Effect (SZE) signal, , its X-ray analogue, , and total mass…
