JWST resolves jet-driven H2 and ionized outflows in radio galaxy 3C305
B. Sebastian, P. M. Ogle, P. Guillard +17
We present JWST MIRI MRS, NIRSpec, NIRCam, and MIRI imaging observations of 3C 305, a radio galaxy with a compact jet that is confined within the galaxy. We use the H2 0-0 S(1)-S(7…
SDSO1 is a Shocked Ghost Planetary Nebula in Front of M 31
Patrick Ogle, Mark Petersen, R. Michael Rich +12
We present new, deep narrowband imagery and discuss the nature of SDSO 1, the large [O III]-emitting nebula centered 1.5 degrees SE of M 31. We find strong evidence to support the…
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…
Magnetic field in the Lobes of the Seyfert Galaxy NGC3516: Suggestions of a Helical field
Salmoli Ghosh, P. Kharb, E. Sajjanhar +2
We present polarization images from the Karl G. Jansky Very Large Array (VLA) and the Giant {Metrewave} Radio Telescope (GMRT) at 5.5, 10 GHz and 663 MHz of the changing-look (CL)…
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…
