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...

A complete overview of the stellar, gas and dust contents of galaxies is key to understanding their assembly at early times. However, an estimation of molecular and atomic gas reservoirs at high redshift relies on various indirect tracers, while robust dust mass measurements require multiband far-infrared continuum obs...

We present results from a survey of the Hubble Ultra-Deep Field using the Wide-Field Slitless Spectroscopic (WFSS) capability of the Mid-Infrared Instrument (MIRI) on JWST, demonstrating the capabilities of this new mode. We describe the data reduction and calibration methodology, and estimate calibration uncertainties...

Context.
Luminous infrared galaxies (LIRGs) represent a key phase of galaxy evolution that is characterized by intense star formation, frequent mergers, and in some cases significant active galactic nucleus (AGN) activity. Polycyclic aromatic hydrocarbons (PAHs) and far-infrared (FIR) cooling lines provide powerful...
