A novel analysis of contamination in Lyman-break galaxy samples at : spatial correlation with intermediate-redshift galaxies at
Miftahul Hilmi, Nicha Leethochawalit, Michele Trenti +1
Potential contamination from low/intermediate-redshift galaxies, such as objects with a prominent Balmer break, affects the photometric selection of high-redshift galaxies through…
BEACON: JWST NIRCam Pure-parallel Imaging Survey. I. Survey Design and Initial Results
Takahiro Morishita, Charlotte A. Mason, Kimi C. Kreilgaard +32
We introduce the Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam (BEACON) survey, a JWST Cycle2 program allocated up to 600 pure-parallel hours of observations. BEA…
ASTRODEEP-JWST: NIRCam-HST multiband photometry and redshifts for half a million sources in six extragalactic deep fields
E. Merlin, P. Santini, D. Paris +52
We present a set of photometric catalogs primarily aimed at providing the community with a comprehensive database for the study of galaxy populations in the high redshift Universe.…
Unveiling Multiple Physical Processes on a Cluster Galaxy at z=0.3 Using JWST
Peter J. Watson, Benedetta Vulcani, Ariel Werle +5
We present a study of a previously identified candidate jellyfish galaxy in the Abell 2744 cluster, F0083, which showed faint signs of a tidal interaction in archival imaging. We u…
The rates and host galaxies of pair-instability supernovae through cosmic time: Predictions from BPASS and IllustrisTNG
Max M. Briel, Benjamin Metha, Jan J. Eldridge +2
Pair-instability supernovae (PISNe) have long been predicted to be the final fates of near-zero-metallicity very massive stars (, $\mathrm{M}_\mathrm{ZAMS} \gtrsim 1…
Accelerated Emergence of Evolved Galaxies in Early Overdensities at
Takahiro Morishita, Zhaoran Liu, Massimo Stiavelli +8
We report the identification of two galaxy overdensities at in the sightline of the galaxy cluster Abell 2744. These overdensities consist of 25 and 17 member galaxies,…
The BoRG- Survey: Abundance and Mass-to-light Ratio of Luminous Galaxies from Independent Sight Lines with NIRSpec
Sofía Rojas-Ruiz, Micaela B. Bagley, Guido Roberts-Borsani +12
We present new results on the rest-frame UV luminosity function (UVLF) and stellar mass-to-light (M/L) ratio of bright (M mag) spectroscopically-confirmed gal…
The BoRG-JWST Survey: Program Overview and First Confirmations of Luminous Reionization-Era Galaxies from Pure-Parallel Observations
Guido Roberts-Borsani, Micaela Bagley, Sofía Rojas-Ruiz +18
We present the BoRG-JWST survey, a combination of two JWST Cycle 1 programs aimed at obtaining NIRSpec spectroscopy of representative, UV-bright galaxy candidates across 2…
A forward-modelling approach to overcome PSF smearing and fit flexible models to the chemical structure of galaxies
Benjamin Metha, Simon Birrer, Tommaso Treu +3
Historically, metallicity profiles of galaxies have been modelled using a radially symmetric, two-parameter linear model, which reveals that most galaxies are more metal-rich in th…
The rate and contribution of mergers to mass assembly from NIRCam observations of galaxy candidates up to 13.3 billion years ago
Nicolò Dalmasso, Antonello Calabrò, Nicha Leethochawalit +8
We present an analysis of the galaxy merger rate in the redshift range (i.e. about 1.5 to 0.5 Gyr after the Big Bang) based on visually identified galaxy mergers from m…
A geostatistical analysis of multiscale metallicity variations in galaxies -- III. Spatial resolution and data quality limits
Benjamin Metha, Michele Trenti, Andrew Battisti +1
Geostatistical methods are powerful tools for understanding the spatial structure of the metallicity distribution of galaxies, and enable construction of accurate predictive models…
Galaxy clustering at cosmic dawn from JWST/NIRCam observations to redshift z11
Nicolò Dalmasso, Nicha Leethochawalit, Michele Trenti +1
We report measurements of the galaxy two-point correlation function at cosmic dawn, using photometrically-selected sources from the JWST Advanced Deep Extragalactic Survey (JADES).…
Diverse Oxygen Abundance in Early Galaxies Unveiled by Auroral Line Analysis with JWST
Takahiro Morishita, Massimo Stiavelli, Claudio Grillo +10
We present deep JWST NIRSpec observations in the sightline of MACS J1149.5+2223, a massive cluster of galaxies at . We report the spectroscopic redshift of 28 sources at $3…
