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…
Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy
Gregor Rihtaršič, Maruša Bradač, Guillaume Desprez +23
We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…
Euclid Quick Data Release (Q1). The first catalogue of strong-lensing galaxy clusters
Euclid Collaboration, P. Bergamini, M. Meneghetti +375
We present the first catalogue of strong lensing galaxy clusters identified in the Euclid Quick Release 1 observations (covering ). This catalogue is the resu…
The powerful lens galaxy cluster PLCK G287.0+32.9 ()
Maurizio D'Addona, Amata Mercurio, Piero Rosati +17
We present a new high-precision strong lensing model of PLCK G287.032.9, a massive lens galaxy cluster at , with the aim to get an accurate estimation of its effective…
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…
CLASH-VLT: Dissecting the Frontier Fields Galaxy Cluster MACS J0416.1-2403 with Spectra of Member Galaxies
I. Balestra, A. Mercurio, B. Sartoris +33
We present VIMOS-VLT spectroscopy of the Frontier Fields cluster MACS~J0416.1-2403 (z=0.397). Taken as part of the CLASH-VLT survey, the large spectroscopic campaign provided more…
The origin of peak-offsets in weak-lensing maps
J. P. Dietrich, A. Böhnert, M. Lombardi +2
Centroid positions of peaks identified in weak lensing mass maps often show offsets with respect to other means of identifying halo centres, like position of the brightest cluster…
