MICONIC: The multiphase circumnuclear region of Centaurus A as seen with JWST/MIRI MRS observations. I. Spectral inventory and properties of the warm molecular disk
L. Evangelista, P. Guillard, J. Martin +21
Supermassive black holes power Active Galactic Nuclei (AGN), injecting energy that regulates accretion and shapes host galaxies. We investigate the morphology, excitation, and kine…
Resolved molecular gas and star-formation in massive unquenched spirals : I. UGC 8179
Romane Cologni, Simon Flesch, Philippe Salomé +7
Recent studies have uncovered a rare population of super-massive (M* > 1e11 Msun) star-forming spiral galaxies, Super Spiral Galaxies (SSGs), whose existence challenges classical q…
Jet-driven shocks and turbulence in radio-loud Active Galactic Nuclei observed with JWST MIRI/MRS
Rogemar A. Riffel, Gabriel L. Souza-Oliveira, Luis Colina +34
Jet-cloud interactions are a key manifestation of Active Galactic Nucleus (AGN) feedback on nuclear scales, distinct from the large-scale radio-mode feedback that suppresses gas co…
Turning JWST/MIRI backgrounds into a survey of diffuse molecular hydrogen
E. Nigou, B. Godard, P. Guillard +3
Context. A statistically significant sampling of H2 rotational excitation in the diffuse interstellar medium (ISM) is essential to identifying its excitation mechanisms and assessi…
JWST imaging of the Pleiades: anisotropy of turbulence in the cold neutral medium
G. Vigoureux, N. Flagey, F. Boulanger +14
Interstellar medium studies rely on magnetohydrodynamic (MHD) turbulence as a framework for interpretation. In this context, the statistical characterization of interstellar observ…
JWST observations of photodissociation regions: II. Warm molecular Hydrogen spectroscopy in the Horsehead nebula
M. Zannese, P. Guillard, A. Abergel +16
H2 is the most abundant molecule in the interstellar medium and is a useful tool to study photodissociation regions, where radiative feedback from massive stars on molecular clouds…
