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…
What obscures low X-ray-scattering active galactic nuclei?
S. F. Hoenig, P. Gandhi, D. Asmus +4
X-ray surveys have revealed a new class of active galactic nuclei (AGN) with a very low observed fraction of scattered soft X-rays, f_scat < 0.5%. Based on X-ray modeling these "X-…
Dust in the polar region as a major contributor to the IR emission of AGN
Sebastian F. Hoenig, Makoto Kishimoto, Konrad R. W. Tristram +7
(abridged) It is generally assumed that the distribution of dust on parsec scales forms a geometrically- and optically-thick entity in the equatorial plane around the accretion dis…
Probing the innermost dusty structure in AGN with mid-IR and near-IR interferometers
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +5
With mid-IR and near-IR long-baseline interferometers, we are now mapping the radial distribution of the dusty accreting material in AGNs at sub-pc scales. We currently focus on Ty…
Mutiwavelength Observations of Radio Galaxy 3C 120 with XMM-Newton
P. M. Ogle, S. W. Davis, R. R. J. Antonucci +5
We present XMM-Newton observations of the radio galaxy 3C 120. The hard X-ray spectrum contains a marginally resolved Fe I K-alpha emission line with FWHM=9,000 km/s and an equival…
The Ly-edge paradox and the need for obscured QSOs
R. Maiolino, M. Salvati, A. Marconi +1
Based on the most recent QSO ultraviolet spectra, the covering factor of the clouds of the Broad Line Region (BLR) is about 30%, or larger. This value would imply that in at least…
Modelling the Cloverleaf: Contribution of a Galaxy Cluster at z~1.7
J. -P. Kneib, D. Alloin, Y. Mellier +3
We present a new investigation of the Cloverleaf (z=2.558) based on the combination of archival HST/WFPC2 data, recent IRAM CO(7-6) maps and wide field CFHT/FOCAM images. The deepe…
