PDRs4All VIII: Mid-IR emission line inventory of the Orion Bar
Dries Van De Putte, Raphael Meshaka, Boris Trahin +135
Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…

PDRs4All VII. The 3.3 m aromatic infrared band as a tracer of physical properties of the ISM in galaxies
Ilane Schroetter, Olivier Berné, Christine Joblin +9
Aromatic infrared bands (AIBs) are a set of broad emission bands at 3.3, 6.2, 7.7, 8.6, 11.2, and 12.7 m, seen in the infrared spectra of most galaxies. With JWST, the 3.3 …
