No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
Enhanced strong-lensing model of MACS~J0138.02155 based on new JWST and VLT/MUSE observations
Ana Acebron, Pietro Bergamini, Piero Rosati +10
We present a new parametric strong lensing analysis of the galaxy cluster MACS J0138.0-2155 at z = 0.336, the first known to show two multiply-imaged supernova (SN) siblings, SN Re…
Spectroscopic confirmation of the galaxy clusters CARLA J0950+2743 at z=2.363, and CARLA-Ser J0950+2743 at z=2.243
Kirill A. Grishin, Simona Mei, Igor V. Chilingarian +6
Galaxy clusters, being the largest gravitationally bound structures in the Universe, are a powerful tool to study mass assembly at different epochs. At z2 they give an unique op…
Multiple AGN activity during the BCG assembly of XDCPJ0044.0-2033 at z~1.6
A. Travascio, A. Bongiorno, P. Tozzi +13
Undisturbed galaxy clusters are characterized by a massive and large elliptical galaxy at their center, i.e. the Brightest Cluster Galaxy (BCG). How these central galaxies form is…
Mass distribution in the core of MACS J1206: robust modeling from an exceptionally large sample of central multiple images
G. B. Caminha, C. Grillo, P. Rosati +24
We present a new strong lensing analysis of the galaxy cluster MACS J1206.2-0847 (MACS 1206), at z=0.44, using deep spectroscopy from CLASH-VLT and VLT/MUSE archival data in combin…
