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…
Decoupling the AGN outflow and star-forming disk kinematics in the nuclear region of NGC 7582 with JWST NIRSpec and MIRI/MRS
Oscar Veenema, Niranjan Thatte, Dimitra Rigopoulou +24
We present a detailed study of the inner regions of NGC~7582, a nearby Seyfert~2 galaxy, from the Galaxy Activity, Torus and Outflow Survey (GATOS). The galaxy hosts a circumnuclea…
The Galaxy Activity, Torus, and outflow Survey (GATOS) XIII: Coupling Driven H2 Excitation in Seyferts
Daniel E. Delaney, Erin K. S. Hicks, Lulu Zhang +31
We utilize JWST/MIRI IFU observations from the Galaxy Activity, Torus and Outflow Survey (GATOS) to investigate the diverse range of ionized outflow rates of obscured AGN with simi…
Modelling the expulsion of baryons from haloes from first principles: the role of feedback and of the cosmological constant
Oscar Veenema, Daniele Sorini, Sownak Bose
The extent to which galactic-scale astrophysical processes conspire with the underlying cosmological model to expel baryons from haloes remains a central question in galaxy formati…
The PAH 3.4 micron feature as a tracer of shielding in the Orion Bar and NGC 6240
N. Thatte, D. Rigopoulou, F. R. Donnan +8
We have carried out a detailed analysis of the 3.4 micron spectral feature arising from Polycyclic Aromatic Hydrocarbons (PAH), using JWST archival data. For the first time in an e…
Impact of AGN and nuclear star formation on the ISM turbulence of galaxies: Insights from JWST/MIRI spectroscopy
Rogemar A. Riffel, Luis Colina, José Henrique Costa-Souza +31
Active galactic nuclei (AGN), star formation (SF), and galaxy interactions can drive turbulence in the gas of the ISM, which in turn plays a role in the SF within galaxies. The imp…
