SMA Observations of the Archetypal Compact Steep-spectrum Radio Source 3C 303.1
Rushikesh Bhutkar, Mark Gurwell, Christopher O'Dea +5
AGN (active galactic nuclei) feedback plays a crucial role in shaping galaxy evolution. Numerical simulations show that the kinetic energy transfer efficiency from radio jets to in…
A Deep Chandra View of Abell 2597: Bubbles, Shocks, Cold Fueling, and a Plasma Depletion Layer
Osase Omoruyi, Grant Tremblay, Stefi A. Baum +14
To examine how AGN feedback shapes the intracluster medium (ICM) and fuels black hole accretion in the cool-core galaxy cluster Abell 2597, we present deep (600 ks) Chandra X…
What drives kpc-scale outflows in Radio-Quiet AGN? Insights from a Polarimetric Study
Salmoli Ghosh, Preeti Kharb, Biny Sebastian +5
We present a review of our findings on the origin, drivers, nature, and impact of kiloparsec-scale radio emission in radio-quiet (RQ) AGN. Using radio polarimetric techniques, we p…
Mapping feedback signatures in 3C 297: A quasar-host merger at Cosmic Noon
Chetna Duggal, Christopher P. O'Dea, Stefi A. Baum +6
We present a study of quasar host galaxy 3C 297 which is home to a powerful bent-jet radio source suggesting vigorous interaction with a dense ISM and/or jet precession. Archival H…
A Comprehensive Multiwavelength Study of the OH Megamaser galaxy IRAS 09320+6134
Claudia M. Cassanta, Rogemar A. Riffel, Andrew Robinson +7
We present a multiwavelength study of the gas distribution, kinematics and excitation of the OH megamaser galaxy IRAS 09320+6134 (UGC 5101) using Gemini Multi-Object Spectrograph I…
Jet-mode feedback in NGC 5972: insights from resolved MUSE, GMRT and VLA observations
Arshi Ali, Biny Sebastian, Darshan Kakkad +10
NGC 5972, a Voorwerp galaxy, features a helical-shaped extended emission-line region (EELR) with a radius > 10 kpc and a S-shaped radio structure spanning about 470 kpc. We use VLT…
The JWST View of Cygnus A: Jet-Driven Coronal Outflow with a Twist
Patrick M. Ogle, B. Sebastian, A. Aravindan +29
We present first results from James Webb Space Telescope (JWST) Near-Infrared Spectrograph (NIRSpec), Mid-Infrared Instrument (MIRI), and Keck Cosmic Webb Imager (KCWI) integral fi…
Magnetic Field Structures In and Around Seyfert Galaxy Outflows
Salmoli Ghosh, P. Kharb, B. Sebastian +5
We present radio polarimetric images of 12 Seyfert and Low-Ionization Nuclear Emission-line Region (LINER) galaxies belonging to the Centre for Astrophysics (CfA)+12 micron sample…
Gemini IFU, VLA, and HST observation of the OH Megamaser Galaxy IRAS17526+3253
Dinalva A. Sales, A. Robinson, R. A. Riffel +7
We present a multiwavelength study of the OH megamaser galaxy (OHMG) IRAS17526+3253, based on new Gemini Multi-Object Spectrograph Integral Field Unit (GMOS/IFU) observations, Hubb…
The Close AGN Reference Survey (CARS): SOFIA detects spatially-resolved [CII] emission in the luminous AGN HE0433-1028
G. Busch, B. Husemann, I. Smirnova-Pinchukova +18
We report spatially-resolved [CII] m observations of HE 0433-1028, which is the first detection of a nearby luminous AGN (redshift 0.0355) with FIFI-LS onboard the airborn…
Star formation and gas inflows in the OH Megamaser galaxy IRAS03056+2034
C. Hekatelyne, Rogemar A. Riffel, Dinalva Sales +6
We have obtained observations of the OH Megamaser galaxy IRAS03056+0234 using Gemini Multi-Object Spectrograph (GMOS) Integral Field Unit (IFU), Very Large Array (VLA) and Hubble S…
The puzzling case of the radio-loud QSO 3C 186: a gravitational wave recoiling black hole in a young radio source?
M. Chiaberge, J. C. Ely, E. T. Meyer +14
Context. Radio-loud AGNs with powerful relativistic jets are thought to be associated with rapidly spinning black holes (BHs). BH spin-up may result from a number of processes, inc…
Cold, clumpy accretion onto an active supermassive black hole
Grant R. Tremblay, J. B. Raymond Oonk, Françoise Combes +22
Supermassive black holes in galaxy centres can grow by the accretion of gas, liberating energy that might regulate star formation on galaxy-wide scales. The nature of the gaseous f…
An embedded active nucleus in the OH megamaser galaxy IRAS16399-0937
Dinalva A. Sales, A. Robinson, D. J. Axon +7
We present a multiwavelength study of the OH Megamaser galaxy (OHMG) IRAS16399-0937, based on new HST/ACS F814W and H+[NII] images and archive data from HST, 2MASS, Spitzer, Her…
