Evidence of Jet-ambient Gas Interactions in the Emission-line Region of Seyfert Galaxies

Collimated outflows (ranging from barely collimated winds to actual jets) are present in a wide range of astrophysical objects, four types of them being represented at this conference, namely young stellar objects, planetary nebulae, radio galaxies and Seyfert galaxies. In this paper, I first try to give a brief overview of the basic properties of the outflows and their environments, as they ar...

The Molecular Gas in the Circumnuclear Region of Seyfert Galaxies1

Sub-arcsecond IRAM Plateau de Bure mm-interferometric observations of the CO (2-1) line emission in the Seyfert 1 NGC 3227 and the Seyfert 2 NGC 1068 have revealed complex kinematic systems in the inner 100 pc to 300 pc that are not consistent with pure circular motion in the host galaxies. Modeling of these kinematic systems with elliptical orbits in the plane of the host galaxy (representing ...

Sub-Relativistic Radio Jets and Parsec-Scale Absorption in Two Seyfert Galaxies

The Very Long Baseline Array has been used at 15 GHz to image the milliarcsecond structure of the Seyfert galaxies Mrk 231 and Mrk 348 at two epochs separated by about 1.7 yr. Both galaxies contain parsec-scale double radio sources whose components have brightness temperatures of 109–1011 K, implying that they are generated by synchrotron emission. The nuclear components are identified by their...

A Physically Consistent Model for X-ray Emission by Seyfert 2 Galaxies Demonstrated on Ngc 1068

Preliminary analysis of the X-ray spectrum of NGC 1068 obtained by the RGS spectrometer on board XMM-Newton is presented. A physically consistent model is developed in order to quantitatively describe the reprocessing of the central AGN continuum source into the discrete X-ray emission observed in Seyfert 2 galaxies. All the important atomic processes are taken into account, including photoexci...

Continuum emission in NGC 1068 and NGC 3147 : Indications for a turnover in the core spectra ⋆

We present new interferometric observations of the continuum emission at mm wavelengths in the Seyfert galaxies NGC 1068 and NGC 3147. Three mm continuum peaks are detected in NGC 1068, one centered on the core, one associated with the jet and the third one with the counter-jet. This is the first significant detection of the radio jet and counter-jet at mm wavelengths in NGC 1068. While the flu...
