UNCOVER | UNCOVERing the extended strong lensing structures of Abell 2744 with the deepest JWST imaging

A 1.46' x 0.85' cutout of an UNCOVER color-composite image exhibiting the many newly discovered SL features and candidates in the north-western sub-structure of A2744. The filter stacks used are: Blue – F090W+F115W+F150W, Green – F200W+F277W and Red – F356W+F410M+F444W. We mark the newly identified and numbered multiple image systems in green and multiple image candidates in yellow. Cluster galaxies left free to vary in our SL model are shown in red. The critical curves of our SL model for source redshifts Zs = 1.6881, the redshift of system 1 and Zs = 10 are shown in blue and purple, respectively.
