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 RihtarÅ¡iÄ, MaruÅ¡a BradaÄ, 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…
