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…
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…
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…
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…
Rotation and flipping invariant self-organizing maps with astronomical images: A cookbook and application to the VLA Sky Survey QuickLook images
A. N. Vantyghem, T. J. Galvin, B. Sebastian +12
Modern wide field radio surveys typically detect millions of objects. Techniques based on machine learning are proving to be useful for classifying large numbers of objects. The se…
A VLBA-uGMRT search for candidate binary black holes: Study of six X-shaped radio galaxies with double-peaked emission lines
Biny Sebastian, Anderson Caproni, Preeti Kharb +6
Identifying methods to discover dual AGN has proven to be challenging. Several indirect tracers have been explored in the literature, including X/S-shaped radio morphologies and do…
New Black Hole Spin Values for Sagittarius A* Obtained with the Outflow Method
Ruth A. Daly, Megan Donahue, Christopher P. O'Dea +3
Six archival Chandra observations are matched with eight sets of radio data and studied in the context of the outflow method to measure and study the spin properties of $\rm{Sgr ~A…
A detailed study of the polarisation convention of the Giant Metrewave Radio Telescope
Poonam Chandra, S. Suresh Kumar, Sanjay Kudale +5
Our work aims to investigate the polarisation convention of the Giant Metrewave Radio Telescope (GMRT) radio telescope and understand whether the telescope follows the standard IAU…
Non-thermal emission from massive star forming regions: A possible SNR candidate G351.7-1.2?
V. S. Veena, S. Vig, B. Sebastian +3
We present low frequency wide band observations (300-500 MHz) of the star forming complex G351.7-1.2 using upgraded Giant Metrewave Radio Telescope (uGMRT), India. Combining this w…
