Halfway to the Peak: Ice Absorption Bands at z ≈ 0.5 with JWST MIRI/MRS

Halfway to the Peak: Ice Absorption Bands at z ≈ 0.5 with JWST MIRI/MRS

This paper presents the first combined detections of CO _2 , CO, XCN, and water ices beyond the local Universe. We find gas-phase CO in addition to the solid phase CO. Our source, SSTXFLS J172458.3+591545, is a z = 0.494 star-forming galaxy that also hosts a deeply obscured AGN. The profiles of its...
