PHANGS-JWST: the largest extragalactic molecular cloud catalog traced by polycyclic aromatic hydrocarbon emission
Z. Bazzi, D. Colombo, F. Bigiel +25
High-resolution JWST images of nearby spiral galaxies reveal polycyclic aromatic hydrocarbon (PAH) emission structures that trace molecular gas, including CO-dark regions. We ident…

Resolved HII regions in NGC 253: Ionized gas structure and suggestions of a universal density-surface brightness relation
Rebecca L. McClain, Adam K. Leroy, Enrico Congiu +23
We use the full-disk VLT-MUSE mosaic of NGC 253 to identify 2492 HII regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the la…

The PHANGS-MUSE/HST-Halpha Nebulae Catalogue
A. T. Barnes, R. Chandar, K. Kreckel +38
We present the PHANGS-MUSE/HST-Halpha nebulae catalogue, comprising 5177 spatially resolved nebulae across 19 nearby star-forming galaxies (< 20 Mpc), based on high-resolution Halp…
