Unscrambling the Lensed Galaxies in JWST Images behind SMACS 0723

The first deep field images from the James Webb Space Telescope (JWST) of galaxy cluster SMACS~J0723.3-7327 reveal a wealth new lensed at uncharted infrared wavelengths, with unprecedented depth and resolution. Here we securely identify 14 sets multiply imaged galaxies totalling 42 images, adding to five bright multiply-imaged already known Hubble data. We find examples arcs crossing critical curves, allowing detailed community follow-up, such as JWST spectroscopy for precise redshift determinations, measurements chemical abundances internal gas dynamics very distant, young galaxies. One arc contains pair compact knots that are magnified by factor hundreds, features microlensed transient. also detect an Einstein cross candidate only visible thanks JWST's superb Our parametric lens model is available through following link: https://www.dropbox.com/sh/gwup2lvks0jsqe5/AAC2RRSKce0aX-lIFCc9vhBXa?dl=0, will be regularly updated using additional spectroscopic redshifts. constrained 16 these galaxies, three which have redshifts, reproduces multiple better than rms $0.5^{\prime \prime}$, accurate magnification estimates high-redshift intracluster light extends beyond members, exhibiting large-scale suggest significant past dynamical disturbance. This work represents taste enhanced power lensing-related science.
