We present a multiwavelength analysis of a young bubble in the nuclear starburst of NGC 253 using new JWST MIRI–MRS observations together with archival ALMA (100, 350, 690 GHz) and Chandra data. The MIRI maps reveal a prominent bubble-like structure in both ionized and molecular emission lines. The bubble is spatially...

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...

The Tully-Fisher (TF) relation is an empirical tool for estimating distances to spiral galaxies. Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity (PV) Survey uses photometric position angles (PAs) to place its fibers along the semi-major axis of the galaxy and infer maximum rotational velocities for ≈ 53,0...
