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…
Early Results from GLASS-JWST. XXV. Electron Density in the Interstellar Medium at with NIRSpec High-resolution Spectroscopy
Sijia Li, Xin Wang, Yuguang Chen +17
The electron density () of the interstellar medium (ISM) in star-forming galaxies is intimately linked to star formation and ionization condition. Using the high-resol…
Not just PAH: why galaxies turn red in the Near-Infrared
Benedetta Vulcani, Tommaso Treu, Matthew Malkan +11
We measure the spectral properties of a sample of 20 galaxies at z~0.35 selected for having surprisingly red JWST/NIRCAM F200W-F444W colors. 19 galaxies were observed with JWST/NIR…
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…
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…
A "Rosetta Stone" for Studies of Spatial Variation in Astrophysical Data: Power Spectra, Semivariograms, Structure Functions, and More
Benjamin Metha, Sabrina Berger
From the turbulent interstellar medium to the cosmic web, astronomers in many different fields have needed to make sense of spatial data describing our Universe. Through different…
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…
