GLIMPSE-D is a JWST DDT program (#9223) conducting deep G395M spectroscopy of the best-studied lensing cluster, Abell S1063. This field also received the deepest NIRCam imaging exposures in the Cycle 2 large JWST program GLIMPSE (#3293). Led by Seiji Fujimoto (U. Toronto) and Rohan Naidu (MIT), GLIMPSE-D delivers unprecedented medium-grating spectra for hundreds of high-redshift galaxies, maximally leveraging the deepest imaging data together with the strong lensing effect.
The panels above show, from left to right: the RGB color image from GLIMPSE NIRCam data, the NIRSpec MSA footprints of GLIMPSE-D, and our team meeting held in Boston in July 2025. Many active young folks have been leading the efforts of analyzing the data and writing papers, and we anticipate multiple papers submitted in the coming weeks and months — stay tuned!
