BEASTS (JWST Cycle 1, GO 2659) used NIRSpec IFU PRISM spectroscopy to observe five of the brightest z ≈ 9 galaxy candidates in COSMOS. Three are confirmed at z = 7.2–8.2, each resolved into two or three components. See the first results.
Coming next: Euclid × JWST
Cycle 5 program GO 11286 (PI Allen, co-PIs Oesch and Weaver) will observe seven of the most luminous z ≈ 9 candidates found by Euclid. More.
