Unveiling the Aromatic and Aliphatic Universe at Redshifts z ∼ 0.2–0.5 with JWST NIRCam/WFSS

Unveiling the Aromatic and Aliphatic Universe at Redshifts z ∼ 0.2–0.5 with JWST NIRCam/WFSS

Utilizing deep NIRCam/WFSS data from JWST’s FRESCO program, we spectroscopically survey the 3.3 μ m aromatic and 3.4 μ m aliphatic C–H stretching emission bands of polycyclic aromatic hydrocarbon (PAH) molecules in galaxies at redshifts z ∼ 0.2–0.5. Unlike pre-JWST studies, largely limited to infrar...
