CANUCS/Technicolor Data Release 1: Imaging, Photometry, Slit Spectroscopy, and Stellar Population Parameters

Ghassan T. E. Sarrouh, Yoshihisa Asada, Nicholas S. Martis +44

We present the first data release of the CAnadian NIRISS Unbiased Cluster Survey (CANUCS), a JWST Cycle 1 GTO program targeting 5 lensing clusters and flanking fields in parallel (…

JWST lens model for A370: A very low dark matter fraction for a brightest cluster galaxy and lensing properties for the Dragon arc

Jose M. Diego, Fengwu Sun, Jose M. Palencia +8

We present a new lens model for the galaxy cluster Abell 370 based on previously spectroscopically confirmed lensed galaxies and new lensed systems identified in JWST dat…

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…

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…

CDM not dead yet: massive high-z Balmer break galaxies are less common than previously reported

Guillaume Desprez, Nicholas S. Martis, Yoshihisa Asada +15

Early JWST observations that targeted so-called double-break sources (attributed to Lyman and Balmer breaks at ), reported a previously unknown population of very massive, evo…
