An improved Magellan weak lensing analysis of the galaxy cluster Abell 2744
Davide Abriola, Daniele Della Pergola, Marco Lombardi +4
We present a new weak lensing analysis of the Hubble Frontier Fields galaxy cluster Abell 2744 ( = 0.308) using new Magellan/MegaCam multi-band imaging data. We carry out…
Augmenting the power of time-delay cosmography in lens galaxy clusters by probing their member galaxies. II. Cosmic chronometers
P. Bergamini, S. Schuldt, A. Acebron +9
We present a novel approach to measuring the expansion rate and the geometry of the Universe, which combine time-delay cosmography in lens galaxy clusters with pure samples of 'cos…
UV-continuum slopes of individual clumps and their evolution
A. Bolamperti, A. Zanella, U. Meštrić +11
We study the ultraviolet (UV) continuum slope of a sample of 166 clumps, individual star-forming regions observed in high redshift galaxies. They are hosted by 67 galaxies with…
A persistent excess of galaxy-galaxy strong lensing observed in galaxy clusters
Massimo Meneghetti, Weiguang Cui, Elena Rasia +18
Previous studies have revealed that the estimated probability of galaxy-galaxy strong lensing in observed galaxy clusters exceeds the expectations from the Cold Dark Matter cos…
Early results from GLASS-JWST. XX: Unveiling a population of "red-excess'' galaxies in Abell2744 and in the coeval field
Benedetta Vulcani, Tommaso Treu, Antonello Calabro +26
We combine JWST/NIRCam imaging and MUSE data to characterize the properties of galaxies in different environmental conditions in the cluster Abell2744 () and in its immed…
The Kormendy relation of early-type galaxies as a function of wavelength in Abell S1063, MACS J0416.1-2403, and MACS J1149.5+2223
L. Tortorelli, A. Mercurio, G. Granata +9
The wavelength dependence of the Kormendy relation (KR) is well characterised at low redshift but poorly studied at intermediate redshifts. The KR provides information on the evolu…
