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…

Novel insights into the Coma cluster kinematics with DESI. I. Linking mass profile, orbital anisotropy, and galaxy populations

S. Pedratti, L. Pizzuti, M. Fossati +4

We investigate the kinematic properties of the Coma galaxy cluster using a new, large spectroscopic sample of member galaxies, from the Dark Energy Spectroscopic Instrument (DESI).…

CLASH-VLT velocity anisotropy profiles in a stack of massive galaxy clusters

E. Maraboli, A. Biviano, C. Grillo +4

We measure the velocity anisotropy profile of different galaxy cluster member populations by analysing the stacked projected phase space of nine massive ($M_\mathrm{200c}>7…

Bayesian luminosity function estimation in multi-depth datasets with selection effects: A case study for Lyman emitters

Davide Tornotti, Matteo Fossati, Michele Fumagalli +3

We present a hierarchical Bayesian framework designed to infer the luminosity function of any class of object by jointly modelling data from multiple surveys with varying depth, co…
