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…

A Jet-Induced Shock in a Young, Powerful Radio Galaxy at z=3.00

Nick Seymour, Jess W. Broderick, Gael Noirot +9

The bright radio source, GLEAM J091734-001243 (hereafter GLEAM J0917-0012), was previously selected as a candidate ultra-high redshift (z>5) radio galaxy due to its compact radio s…

Improving photometric redshifts of Epoch of Reionization galaxies: a new empirical transmission curve with neutral hydrogen damping wing Ly absorption

Yoshihisa Asada, Guillaume Desprez, Chris J. Willott +12

We present a new analytical model for the attenuation to Epoch of Reionization (EoR) galaxies by proximate neutral hydrogen gas. Many galaxy spectra in the EoR taken by JWST have s…

Detailed Study of Stars and Gas in a z = 8.3 Massive Merger with Extreme Dust Conditions

Anishya Harshan, Roberta Tripodi, Nicholas S. Martis +15

We present galaxy MACS0416-Y1 at z as observed by the CAnadian NIRISS Unbiased Cluster Survey (CANUCS). MACS0416-Y1 has been shown to have extreme dust proper…

The GLEAMing of the first supermassive black holes: III. Radio sources with ultra-faint host galaxies

J. W. Broderick, N. Seymour, G. Drouart +10

We present deep near-infrared -band imaging for 35 of the 53 sources from the high-redshift () radio galaxy candidate sample defined in Broderick et al. (2022). T…

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…

The NuSTAR Serendipitous Survey: the 80-month catalog and source properties of the high-energy emitting AGN and quasar population

Claire L. Greenwell, Lizelke Klindt, George B. Lansbury +32

We present a catalog of hard X-ray serendipitous sources detected in the first 80 months of observations by the Nuclear Spectroscopic Telescope Array (NuSTAR). The NuSTAR serendipi…

CANUCS: An Updated Mass and Magnification Model of Abell 370 with JWST

Rachel Gledhill, Victoria Strait, Guillaume Desprez +9

We report an updated mass and magnification model of galaxy cluster Abell 370 using new NIRCam and NIRISS data from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS). Using Lens…

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…
