While JWST wide-field slitless spectroscopy (WFSS) can disentangle overlapping spectra using two grisms with perpendicular dispersion directions, NIRSpec can achieve this using gratings with different dispersions. Compared with WFSS…","published":"2026-09-29T04:00:00Z","seen":"2026-09-29T07:46:41Z","lang":"en","source":{"id":"arxiv-astro-ph","name":"arXiv astro-ph (astrophysics)","domain":"arxiv.org","outlet":{"wikidata":"Q118398","name":"arXiv","type":"website","country":"US","designations":["bibliographic database","disciplinary repository","online database","open science tool","preprint server","website"]}},"via":"arxiv-astro-ph","topics":["space","astrophysics","astro-ph.im","astro-ph.co","astro-ph.ga"],"authors":["Zihao Wu, Daniel J.
