GATOS: Distinct Feedback Modes in AGN Central Regions Revealed by Spatially Resolved JWST Spectroscopy
Lulu Zhang, Chris Packham, Erin K. S. Hicks +25
This manuscript presents JWST MIRI/MRS observations of the central pc regions of five active galactic nuclei (AGN) spanning a wide range of luminosities (${\rm l…
Spectrally and spatially resolved (sub)millimeter HCN-to-HCO flux ratios in nearby ultraluminous infrared galaxies
Masatoshi Imanishi, Yuri Nishimura, Shunsuke Baba +2
We present the results of our investigations of spectrally and spatially resolved (sub)millimeter HCN-to-HCO flux ratios at J=2-1, J=3-2, and/or J=4-3 in 18 nearby ( 0.1…
Multiphase Gas Structure in the Circumnuclear Region of NGC 5506 Observed with ALMA
Kana Takechi, Hiroshi Nagai, Nozomu Kawakatu +7
We present a study of the multiphase gas structure and kinematics of the circumnuclear disk (CND) of NGC 5506, a nearby edge-on Seyfert galaxy, at a spatial resolution of …
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…
Possible time-variable iron-K emission in the circumnuclear region of the Circinus galaxy
Aiko Miyamoto, Taiki Kawamuro, Hirokazu Odaka +2
We present imaging and spatially resolved spectral analyses of eight Chandra data taken for the Circinus galaxy in 22 years to reveal neutral iron-K emission on a circ…
Millimeter emission from supermassive black hole coronae
S. del Palacio, C. Yang, S. Aalto +28
Active Galactic Nuclei (AGN) host accreting supermassive black holes (SMBHs). The accretion can lead to the formation of a hot, X-ray emitting corona close to the SMBH capable of a…
Molecular gas stratification and disturbed kinematics in the Seyfert galaxy MCG-05-23-16 revealed by JWST and ALMA
D. Esparza-Arredondo, C. Ramos Almeida, A. Audibert +30
Understanding the processes that drive the morphology and kinematics of molecular gas in galaxies is crucial for comprehending star formation and, ultimately, galaxy evolution. Usi…
Polycyclic Aromatic Hydrocarbon Emission in the Central Regions of Three Seyferts the Implication for Underlying Feedback Mechanisms
Lulu Zhang, Ismael García-Bernete, Chris Packham +29
We analyze JWST MIRI/MRS IFU observations of three Seyferts and showcase the intriguing polycyclic aromatic hydrocarbon (PAH) emission characteristics in regions of $\sim 500\,\rm…
The Galaxy Activity, Torus, and Outflow Survey (GATOS). (IV): Exploring Ionized Gas Outflows in Central Kiloparsec Regions of GATOS Seyferts
Lulu Zhang, Chris Packham, Erin K. S. Hicks +33
Utilizing JWST MIRI/MRS IFU observations of the kiloparsec scale central regions, we showcase the diversity of ionized gas distributions and kinematics in six nearby Seyfert galaxi…
A biconical ionised gas outflow and evidence for positive feedback in NGC 7172 uncovered by MIRI/JWST
L. Hermosa Muñoz, A. Alonso-Herrero, M. Pereira-Santaella +35
We present observations of the type-2 Seyfert NGC7172 obtained with the medium-resolution spectrometer (MRS) of the Mid-Infrared Instrument (MIRI) on board of the JWST. This galaxy…
GATOS: missing molecular gas in the outflow of NGC5728 revealed by JWST
R. Davies, T. Shimizu, M. Pereira-Santaella +49
The ionisation cones of NGC5728 have a deficit of molecular gas based on millimetre observations of CO(2-1) emission. Although photoionisation from the active nucleus may lead to s…
