Galaxy clustering measurements out to redshift z8 from Hubble Legacy Fields
Nicolò Dalmasso, Michele Trenti, Nicha Leethochawalit
We present a novel approach for measuring the two-point correlation function of galaxies in narrow pencil beam surveys with varying depths. Our methodology is utilized to expand hi…
Early results from GLASS-JWST. XXVII. The mass-metallicity relation in lensed field galaxies at cosmic noon with NIRISS
Xianlong He, Xin Wang, Tucker Jones +20
We present a measurement of the mass-metallicity relation (MZR) at cosmic noon, using the JWST near-infrared wide-field slitless spectroscopy obtained by the GLASS-JWST Early Relea…
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…
Enhanced Sub-kpc Scale Star-formation: Results From A JWST Size Analysis of 341 Galaxies At 5<z<14
Takahiro Morishita, Massimo Stiavelli, Ranga-Ram Chary +7
We present a comprehensive search and analysis of high-redshift galaxies in a suite of nine public JWST extragalactic fields taken in Cycle 1, covering a total effective search are…
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…
Early Results from GLASS-JWST XXII: Rest frame UV-optical spectral properties of Lyman-alpha emitting galaxies at 3 z 6
Namrata Roy, Alaina Henry, Tommaso Treu +13
Ly emission is possibly the best indirect diagnostic of Lyman continuum (LyC) escape since the conditions that favor the escape of Ly photons are often the same that allows f…
Early Results from GLASS-JWST XXIII: The transmission of Lyman-alpha from UV-faint z ~ 3-6 galaxies
Gonzalo Prieto-Lyon, Charlotte Mason, Sara Mascia +18
Lyman-alpha (Ly) emission from galaxies can be used to trace neutral hydrogen in the epoch of reionization, however, there is a degeneracy between the attenuation of Ly in th…
The Extended [CII] under Construction? Observation of the brightest high-z lensed star-forming galaxy at z = 6.2
Yoshinobu Fudamoto, Akio K. Inoue, Dan Coe +26
We present results of [CII] emission line observations, and report the spectroscopic redshift confirmation of a strongly lensed () star-forming galaxy, MAC…
A massive interacting galaxy 510 million years after the Big Bang
Kristan Boyett, Michele Trenti, Nicha Leethochawalit +24
JWST observations confirm the existence of galaxies as early as 300Myr and at a higher number density than expected based on galaxy formation models and HST observations. Yet, sour…
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…
Localisation of gamma-ray bursts from the combined SpIRIT+HERMES-TP/SP nano-satellite constellation
Matt Thomas, Michele Trenti, Riccardo Campana +24
Multi-messenger observations of the transient sky to detect cosmic explosions and counterparts of gravitational wave mergers critically rely on orbiting wide-FoV telescopes to cove…
The internal metallicity distributions of simulated galaxies from EAGLE, Illustris, and IllustrisTNG at z=1.8-4 as probed by Gamma Ray Burst hosts
Benjamin Metha, Michele Trenti
Massive stars are thought to be progenitors of Long Gamma Ray Bursts (GRBs), most likely with a bias favouring low metallicity progenitors. Because galaxies do not have a constant…
Early Results from GLASS-JWST. XXI: Rapid assembly of a galaxy at z=6.23 revealed by its C/O abundance
Tucker Jones, Ryan Sanders, Yuguang Chen +21
The abundance of carbon relative to oxygen (C/O) is a promising probe of star formation history in the early universe, as the ratio changes with time due to production of these ele…
The GLASS-JWST Early Release Science Program. II. Stage I release of NIRCam imaging and catalogs in the Abell 2744 region
Diego Paris, Emiliano Merlin, Adriano Fontana +27
We present images and a multi-wavelength photometric catalog based on all of the JWST NIRCam observations obtained to date in the region of the Abell 2744 galaxy cluster. These dat…
