Estimating PAH Emission from JWST Imaging

25 March 2025 Polycyclic Aromatic Hydrocarbons (PAHs) are astrophysically interesting (small) dust grains that emit a significant amount of energy in the near and mid-infrared. The James Webb Space Telescope can observe PAH features using its integral field units (IFUs), but these can only observe small regions of the sky at a time. In “ A Spectroscopically Calibrated Prescription for Extracting…
