Exploring the low-mass regime of galaxy-scale strong lensing: Insights into the mass structure of cluster galaxies
Giovanni Granata, Pietro Bergamini, Claudio Grillo +8
We aim at a direct measurement of the compactness of three galaxy-scale lenses in massive clusters, testing the accuracy of the scaling laws that describe the members in strong len…
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…
The puzzling properties of the MACS1149-JD1 galaxy at z=9.11
Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +6
We analyze new JWST NIRCam and NIRSpec data on the redshift 9.11 galaxy MACS1149-JD1. Our NIRCam imaging data reveal that JD1 comprises three spatially distinct components. Our spe…
Euclid Preparation XXXIII. Characterization of convolutional neural networks for the identification of galaxy-galaxy strong lensing events
Euclid Collaboration, L. Leuzzi, M. Meneghetti +216
Forthcoming imaging surveys will potentially increase the number of known galaxy-scale strong lenses by several orders of magnitude. For this to happen, images of tens of millions…
An extremely metal poor star complex in the reionization era: Approaching Population III stars with JWST
E. Vanzella, F. Loiacono, P. Bergamini +31
We present JWST/NIRSpec integral field spectroscopy (IFS) of a lensed Population III candidate stellar complex (dubbed Lensed And Pristine 1, LAP1), with a lensing-corrected stella…
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 GLASS-JWST Early Release Science Program. III. Strong lensing model of Abell 2744 and its infalling regions
Pietro Bergamini, Ana Acebron, Claudio Grillo +23
We present a new high-precision, JWST-based, strong lensing model for the galaxy cluster Abell 2744 at . By combining the deep, high-resolution JWST imaging from the GLAS…
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…
Closing in on the sources of cosmic reionization: first results from the GLASS-JWST program
S. Mascia, L. Pentericci, A. Calabro' +29
The escape fraction of Lyman-continuum (LyC) photons () is a key parameter for determining the sources of cosmic reionization at . At these redshifts, owing to th…
Clues on the presence and segregation of very massive stars in the Sunburst Lyman-continuum cluster at z=2.37
U. Mestric, E. Vanzella, A. Upadhyaya +15
We report the identification of very massive stars (VMS; mass \,\msun) that may be segregated in the center of the young massive star cluster at =2.37 hosted in the lense…
