Jet Cocoons and the Formation of Narrow Line Clouds in Seyfert Galaxies
We present non-adiabatic hydrodynamic simulations of a supersonic light jet propagating into a fully ionized medium of uniform density on a scale representative of the narrow line region (NLR) in Seyfert galaxies with associated radio jets. In this regime the cooling distance of the swept up gas in the bowshock of the jet is of the same order as the transverse extent of the jet bowshock, as opp...
متن کاملJet directions in Seyfert galaxies
Here we present the study of the relative angle between the accretion disk (or radio jet) and the galaxy disk for a sample of Seyfert galaxies selected from a mostly isotropic property, the 60μm flux, and warm infrared colors. We used VLA A-array 3.6cm continuum data and ground based optical imaging, homogeneously observed and reduced to minimize selection effects. For parts of the analysis we ...
متن کاملDirect Measurement of the Jet Geometry in Seyfert Galaxies.
We demonstrate that by combining optical, radio, and X-ray observations of a Seyfert galaxy, it is possible to provide a direct measurement of the angle beta between the direction of the radio jet and the normal to the plane of the spiral host galaxy. To do so, we make the assumptions that the inner radio jet is perpendicular to the X-ray observed inner accretion disk and that the observed jet ...
متن کاملHigh Spatial Resolution Mid-infrared Observations of Three Seyfert Galaxies
Images at 12.5 lm of nuclei of three nearby Seyfert galaxies—NGC 1275, NGC 4151, and NGC 7469— have been obtained with the 10 m Keck Telescope. NGC 7469 is resolved and deconvolution delineates a structure (<0>04) 0>08, or less than 13 26 pc at a position angle of 135 . From a comparison with structure seen at millimeter wavelengths, this structure is interpreted as a disk aligned with the mole...
متن کاملSeyfert Galaxies and BeppoSAX
In this review, rather than present and discuss in detail the first results obtained by BeppoSAX (see Boella et al. 1997 for an overall description of the mission) on Seyfert galaxies (these results are presented in detail elsewhere in this volume, see in particular the contributions by Perola, Comastri and Salvati), I will discuss current ideas on the X–ray emission of both type 1 and 2 object...
