Using JWST/NIRCam images in the A2744 lensed cluster field, they identified a merging system that consists of a highly dusty, HST-dark, star-forming spiral galaxy (galaxy A) and a compact quiescent companion (galaxy B)
The figure shows the two galaxies (top panels) and their SED fitting (bottom panels) where the blue and green lines correspond to the best-fit model of the star-forming and quiescent galaxies, respectively.
