Cosmic evolution of the helium and oxygen abundances in type 2 Active Galactic Nuclei: Helium-loud AGNs
O. L. Dors, M. Armah, G. F. Hägele +14
We derive the helium and oxygen abundances in the Narrow Line Regions (NLRs) of 84 Active Galactic Nuclei (AGNs) spanning two redshift ranges: 65 objects at and 19…
GATOS XIV: The first direct kinematic evidence of dusty outflows from AGN via PAH kinematics of local Seyfert galaxies with JWST
Fergus R. Donnan, Ismael GarcÃa-Bernete, Dimitra Rigopoulou +30
We present the first spatially resolved kinematic evidence for dust in the outflows of Active Galactic Nuclei (AGN). We utilise observations from JWST with NIRSpec IFU and MIRI MRS…
GATOS N: Extended circumnuclear dust emission in nearby Seyfert galaxies surveyed by JWST/MIRI
David J. Rosario, Houda Haidar, Steph Campbell +32
The subarcsecond angular resolution and stable background of JWST has given us the first high-fidelity images of the arcsecond-scale environment around Active Galactic Nuclei (AGNs…
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…
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…
Near-infrared diagnostic diagrams of the gas ionization sources in nearby galaxies: a JWST NIRSpec view
J. H. Costa-Souza, Luis Colina, Rogemar A. Riffel +6
Buried active galactic nuclei and obscured young stellar clusters pose significant challenges to traditional optical diagnostic diagrams. Therefore, developing new tools to trace t…
