Young massive star clusters (YMCs; ${\gtrsim}10^4\rm\,M_\odot$) represent a distinct, extreme mode of star formation and the closest present-day analogues of the environments in which globular clusters and Cosmic Noon stellar populations assembled. Given the extreme dust extinction in the earliest phase of YMC formatio...

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...
