Beyond Idealized PAHs: Infrared Signatures of Carbon-Chain Defects from Shock Synthesis
Xiaoting Tan, Zhao Wang, Zu-Jia Lu +2
Polycyclic aromatic hydrocarbons (PAHs) are widely recognized as carriers of the aromatic infrared bands (AIBs). However, most spectral models rely on idealized structures that fai…
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…
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…
GATOS XI : Excess dust heating in the Narrow Line Regions of nearby AGN revealed with JWST/MIRI
Houda Haidar, David J. Rosario, Ismael GarcÃa-Bernete +38
We present JWST/MIRI imaging of eight nearby Active Galactic Nuclei (AGN) from the GATOS survey to investigate the physical conditions of extended dust in their narrow line regions…
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…
GATOS IX: A Detailed Assessment and Treatment of Emission Line Contamination in JWST/MIRI Images of Nearby Seyfert Galaxies
Steph Campbell, David J. Rosario, Houda Haidar +17
Broadband mid-infrared (MIR) imaging with high spatial resolution is useful to study extended dust structures in the circumnuclear regions of nearby AGN. However, broadband imaging…
