A Salpeter IMF and an NFW halo: Disentangling the dark and stellar mass of an elliptical galaxy through precise lens modelling of a double-source-plane system
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +7
We present a strong lensing analysis of the double source plane lens J0946+1006 (colloquially "Jackpot" lens) to measure the inner dark matter density profile, the stellar-to-halo…
A new measurement with SNe Requiem and Encore using
L. Bazzanini, G. Di Rosa, A. Acebron +24
We present a strong-lensing (SL) analysis of the galaxy cluster MACS J0138.0-2155 (z=0.336), the first known lens cluster discovered to host two distinct multiply imaged Type Ia su…
Dynamical models of cluster members to probe the total mass properties of cluster subhalos. I. A comparison with parametric strong lensing models
Nicola Bianchetti, Claudio Grillo, Giovanni Granata +6
In this series of papers, we present dynamical models of cluster members in strong lensing (SL) galaxy clusters to independently probe the persistent discrepancy reported between S…
A stellar dynamical mass measurement of an inactive black hole at redshift 2
Andrew B. Newman, Meng Gu, Sirio Belli +34
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…
The velocity dispersion function of red galaxies in four Hubble Frontier Fields galaxy clusters
G. Granata, L. Tortorelli, C. Grillo +6
We present a detailed study of the stellar kinematic properties of red member galaxies in the cores of four strong lensing galaxy clusters at intermediate redshifts included in the…
A New Perspective on Galactic Evolution: Studying the Outskirts of the Abell S1063 Galaxy Cluster
L. Pecoraro, A. Mercurio, M. Annunziatella +14
Galaxy physical properties are influenced by their environments, but the processes responsible for mass and environmental quenching and structural transformations remain debated. G…
