A Single Line-Emitter Identified in an Unbiased Search with JWST/NIRSpec: Multi-Object Coronagraphy for Slitless Spectroscopy
Mason S. Huberty, Claudia Scarlata, Matthew J. Hayes +13
We report the detection of a previously unknown object with a single emission line within the Hubble Ultra Deep Field, using a new JWST NIRSpec technique called Multi-Object Corona…
MOCSS: Multi-Object Coronagraphy for JWST/NIRSpec Slitless Spectroscopy
Mason S. Huberty, Claudia Scarlata, Matthew J. Hayes +10
We present an experimental JWST/NIRSpec observational method to obtain G140M/F100LP slitless spectroscopic observations. This "Multi-Object Coronagraphy for Slitless…
JWST & ALMA Joint Analysis with [OII]3726,3729, [OIII]4363, [OIII]88m, and [OIII]52m: Multi-Zone Evolution of Electron Densities at and Its Impact on Metallicity Measurements
Yuichi Harikane, Ryan L. Sanders, Richard Ellis +8
We present a JWST and ALMA detailed study of the ISM properties of high-redshift galaxies. Our JWST/NIRSpec IFU spectroscopy targeting three galaxies at detects key rest-fr…
Glimmers in the Cosmic Dawn. II. A variability census of supermassive black holes across the Universe
Vieri Cammelli, Jonathan C. Tan, Alice R. Young +7
Understanding the origin and evolution of supermassive black holes (SMBH) stands as one of the most important challenges in astrophysics and cosmology, with little current theoreti…
21 Balmer Jump Street: The Nebular Continuum at High Redshift and Implications for the Bright Galaxy Problem, UV Continuum Slopes, and Early Stellar Populations
Harley Katz, Alex J. Cameron, Aayush Saxena +11
We study the physical origin and spectroscopic impact of extreme nebular emission in high-redshift galaxies. The nebular continuum, which can appear during an extreme starburst, is…
Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe
Callum Witten, William McClymont, Nicolas Laporte +12
While JWST has observed galaxies assembling as early as , evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) -- the descendan…
JWST, ALMA, and Keck Spectroscopic Constraints on the UV Luminosity Functions at z~7-14: Clumpiness and Compactness of the Brightest Galaxies in the Early Universe
Yuichi Harikane, Akio K. Inoue, Richard S. Ellis +33
We present the number densities and physical properties of the bright galaxies spectroscopically confirmed at . Our sample is composed of 60 galaxies at $z_\mathrm{spec}…
Chemical Abundances of Early Quiescent Galaxies: New Observations and Modelling Impacts
Marziye Jafariyazani, Andrew B. Newman, Bahram Mobasher +3
Recent stellar chemical abundance measurements of a handful of quiescent galaxies have suggested these galaxies exhibit a remarkably strong -enhancement compared to the…
Glimmers in the Cosmic Dawn: A Census of the Youngest Supermassive Black Holes by Photometric Variability
Matthew J. Hayes, Jonathan C. Tan, Richard S. Ellis +10
We report first results from a deep near infrared campaign with the Hubble Space Telescope to obtain late-epoch images of the Hubble Ultra-Deep Field (HUDF), 10-15 years after the…
The Nature of High / Galaxies in the Epoch of Reionization: Low Carbon Abundance and a Top-Heavy IMF?
Harley Katz, Joakim Rosdahl, Taysun Kimm +11
ALMA observations of galaxies have revealed abnormally high [OIII]/[CII] ratios and [CII] deficits compared to local galaxies. Numero…
The Absence of [CII] 158m Emission in Spectroscopically-Confirmed Galaxies at
N. Laporte, H. Katz, R. S. Ellis +8
The scatter in the relationship between the strength of [CII] 158m emission and the star formation rate at high-redshift has been the source of much recent interest. Although th…
The ALMA Frontier Fields Survey - II. Multiwavelength Photometric analysis of 1.1mm continuum sources in Abell 2744, MACSJ0416.1-2403 and MACSJ1149.5+2223
N. Laporte, F. E. Bauer, P. Troncoso-Iribarren +32
[abridged] The Hubble and Spitzer Space Telescope surveys of the Frontier Fields (FF) provide extremely deep images around six massive, strong-lensing clusters of galaxies. The ALM…
