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…
Scattered synchrotron emission and a giant torus revealed in polarized light in the nearest radio galaxy Centaurus A
F. Marin, D. Hutsemékers, C. -Z. Jiang +5
Centaurus A (Cen A) is the closest radio galaxy and a prime example of a low-luminosity active galactic nucleus (AGN), exhibiting complex emissions across the electromagnetic spect…
The central engine of low-luminosity radio galaxy 3C 270 (NGC 4261)
Chengzhang Jiang, Robert Antonucci, Jose A. Acosta-Pulido +1
We present the polarization spectra of the nucleus of 3C~270. We confirm that the polarization angle of both the continuum and the emission lines are close to perpendicular to the…
Cygnus A Obscuring Torus: Ionized, Atomic or Molecular?
Atharva Bagul, Patrick Ogle, Robert Antonucci +2
The prototypical powerful FR \Romannum{2} radio galaxy Cygnus A fits extremely well into the quasar/radio galaxy unified model: high polarization with an angle almost perpendicular…
