Optical colour maps of Seyfert galaxies . II . More Seyfert 2 s ⋆
We present optical broad band B–I colour maps of a further sample of 10 Seyfert 2 galaxies. In these bands, the contribution from emission lines to the total flux is small, and hence the images predominantly trace the continuum distribution. As in our earlier colour maps of a sample of Seyferts type 1 and 2, we detect extended blue continuum components in the circumnuclear region of several gal...
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...
متن کاملNew Infrared Seyfert Galaxies
We present optical spectra for new infrared Seyfert galaxies obtained with the 2.16m telescope at Bei-jing Astronomical Observatory (BAO). After wavelength and flux calibration, they are classified by the degree of nuclear activity: nine Seyfert 2 and three Seyfert 3 galaxies. In addition, by using the data from de Grijp et al.(1992), we find that (1) there exists a tight correlation between lu...
متن کاملISO Observations of Seyfert Galaxies
A list of 41 Active Galactic Nuclei (AGN) drawn from the CfA sample has been observed with the ISO satellite. The data set consists of 2.5-11.6 m low resolution (3000 km/s) spectra and contempora-neous images obtained through narrow band lters at 6.75 and 9.63 m and a spatial resolution of 3 arcsec per pixel. Apart from a few close-by objects, the 2{12 m spectra are completely dominated by the ...
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 ...
