Early JWST observations have uncovered a new population of red sources that might represent a previously overlooked phase of supermassive black hole growth^(1–3). One of the most intriguing examples is an extremely red, point-like object that was found to be triply-imaged by the strong lensing (SL) cluster Abell 2744⁴. Here we present deep JWST/NIRSpec observations of this object, Abell2744-QSO1. The spectroscopy confirms that the three images are of the same object, and that it is a …
