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 cir…
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…
