TDCOSMO XXI. Accurate stellar velocity dispersions of the SL2S lens sample and the fundamental plane of the lensing mass
Pritom Mozumdar, Shawn Knabel, Tommaso Treu +4
We reanalyzed spectra that were taken as part of the SL2S lens galaxy survey with the goal to obtain the stellar velocity dispersion with a precision and accuracy sufficient for ti…

The collar of early-type galaxies -- probing evolution by focusing on the inner stellar density profile
Rongfu Liu, Alessandro Sonnenfeld, Carlo Nipoti +1
Aims: In this work we aim to investigate the late evolution of ETGs, both observationally and theoretically, by focusing on the stellar mass density profile inside a fixed aperture…

Searching for rotation in X-COP galaxy clusters
Tommaso Bartalesi, Stefano Ettori, Carlo Nipoti
We search for evidence of rotational support by analyzing the thermodynamic profiles of the intracluster medium (ICM) in a sample of nearby, massive galaxy clusters. For each objec…
