Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr
Roberta Tripodi, Nicholas Martis, Vladan Markov +29
The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…
Resolved mass assembly and star formation in Milky Way Progenitors since from JWST/CANUCS: From clumps and mergers to well-ordered disks
Vivian Yun Yan Tan, Adam Muzzin, Ghassan T. E. Sarrouh +17
We present a resolved study of 877 progenitors of Milky Way Analogs (MWAs) at selected with abundance matching in the ten fields of the Canadian NIRISS Unbiased Cluster S…
CANUCS: UV and Ionising Properties of Dwarf Star Forming Galaxies at z = 5 to 7
Anishya Harshan, Maruša Bradač, Roberto Abraham +14
The epoch of reionisation progressed through the emission of ionising photons from galaxies to their local intergalactic medium. In this work, we characterise the dwarf star-formin…
When, Where, and How Star Formation Happens in a Galaxy Pair at Cosmic Noon Using CANUCS JWST/NIRISS Grism Spectroscopy
Vicente Estrada-Carpenter, Marcin Sawicki, Gabe Brammer +13
Spatially resolved studies are key to understanding when, where, and how stars form within galaxies. Using slitless grism spectra and broadband imaging from the CAnadian NIRISS Unb…
CANUCS: Constraining the MACS J0416.1-2403 Strong Lensing Model with JWST NIRISS, NIRSpec and NIRCam
Gregor Rihtaršič, Maruša Bradač, Guillaume Desprez +18
(Abridged) The strong lensing models of galaxy clusters rely on the number and quality of multiple images with spectroscopic redshifts. We present an updated strong lensing model o…
Deep HST/UVIS imaging of the candidate dark galaxy CDG-1
Pieter van Dokkum, Dayi David Li, Roberto Abraham +4
CDG-1 is a tight grouping of four likely globular clusters in the Perseus cluster, and a candidate dark galaxy with little or no diffuse light. Here we provide new constraints on t…
The Firefly Sparkle: The Earliest Stages of the Assembly of A Milky Way-type Galaxy in a 600 Myr Old Universe
Lamiya Mowla, Kartheik Iyer, Yoshihisa Asada +19
The most distant galaxies detected by JWST are assembling in a Universe that is less than 5\% of its present age. At these times, the progenitors of galaxies like the Milky Way are…
Exposing Line Emission: A First Look At The Systematic Differences of Measuring Stellar Masses With JWST NIRCam Medium Versus Wide Band Photometry
Ghassan T. Sarrouh, Adam Muzzin, Kartheik G. Iyer +13
Photometrically derived stellar masses are known to suffer from systematic uncertainties, particularly due to nebular emission contributions to the spectral energy distribution. Us…
Modelling and Subtracting Diffuse Cluster Light in JWST Images: A Relation between the Spatial Distribution of Globular Clusters, Dwarf Galaxies, and Intracluster Light in the Lensing Cluster SMACS 0723
Nicholas S. Martis, Ghassan T. E. Sarrouh, Chris J. Willott +9
We present a methodology for modeling and removing light from cluster galaxies and intracluster light (ICL) from () images of gravitational le…
