The COSMOS-Web ring: in-depth characterization of an Einstein ring lensing system at z~2
W. Mercier, M. Shuntov, R. Gavazzi +34
Aims. We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z=2 that we serendipitously discovered in the COSMOS-Web survey and possibly the most distant lens…
Unveiling the distant Universe: Characterizing Galaxies in the first epoch of COSMOS-Web
Maximilien Franco, Hollis B. Akins, Caitlin M. Casey +47
We report the identification of 15 galaxy candidates at using the initial COSMOS-Web JWST observations over 77 arcmin through four NIRCam filters (F115W, F150W, F277W,…
HSC-CLAUDS survey: The star formation rate functions since z ~ 2 and comparison with hydrodynamical simulations
V. Picouet, S. Arnouts, E. Le Floch +16
Star formation rate functions (SFRFs) give an instantaneous view of the distribution of star formation rates (SFRs) in galaxies at different epochs. They are a complementary and mo…
Relaxed blue ellipticals: accretion-driven stellar growth is a key evolutionary channel for low mass elliptical galaxies
Ilin Lazar, Sugata Kaviraj, Garreth Martin +3
How elliptical galaxies form is a key question in observational cosmology. While the formation of massive ellipticals is strongly linked to mergers, the low mass (Mstar < 10^9.5 MS…
Euclid preparation. XXX. Performance assessment of the NISP Red-Grism through spectroscopic simulations for the Wide and Deep surveys
Euclid Collaboration, L. Gabarra, C. Mancini +232
This work focuses on the pilot run of a simulation campaign aimed at investigating the spectroscopic capabilities of the Euclid Near-Infrared Spectrometer and Photometer (NISP), in…
