JWST Observations of Starbursts: The Motion of Dust—PAH Kinematics of M82 and NGC 253 with JWST/MIRI Spectroscopy
We present an analysis of dust kinematics in the local starburst galaxies M82 (NGC 3034) and NGC 253 using polycyclic aromatic hydrocarbon (PAH) features observed with JWST/MIRI spectroscopy. We are able to produce high-quality velocity maps of the 5.2, 6.2, and 11.3 μm PAH features, as well as numerous lines of molecu...
