CLASH-VLT: The variance in the velocity anisotropy profiles of galaxy clusters
A. Biviano, E. A. Maraboli, L. Pizzuti +9
The velocity anisotropy profiles, , of galaxy clusters are directly related to the shape of the orbits of their member galaxies. Knowledge of is important to underst…
Euclid: Systematic uncertainties from the halo mass conversion on galaxy cluster number count data analyses
T. Gayoux, P. -S. Corasaniti, T. R. G. Richardson +153
The large catalogues of galaxy clusters expected from the Euclid survey will enable cosmological analyses of cluster number counts that require accurate cosmological model predicti…
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 met…
Euclid preparation LXIII. Simulations and nonlinearities beyond CDM. 2. Results from non-standard simulations
Euclid Collaboration, G. Rácz, M. -A. Breton +275
The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observa…
Unveiling the shape: a multi-wavelength analysis of the galaxy clusters Abell 76 and Abell 1307
R. Barrena, L. Pizzuti, G. Chon +1
We analyse the dynamical state of the galaxy clusters Abell 76 and Abell 1307 from the optical point of view, presenting a coherent scenario that responds to the X-ray emissions ob…
