Host Galaxies and Cluster Environment of BL Lac Objects at , > 0.5ain aim of this study is to confirm the apparent evolution previously claimed. A host galaxy was detected in all BL Lac objects at . < 0.7. At higher redshifts our search was not successful. An exception might be PKS 0426–380 (z > 1.03). Here we detected a galaxy, which might be either along the lin

The Real Difference Between Radio-Loud and Radio-Quiet AGNsoud and radio-quiet AGNs. It is quite clear that the real difference between these two classes is the JET. So the discussion should be: why some AGNs have a powerful radio jet and some other don’t have. I will briefly discuss about the possible explanations for this fundamental difference.

Broadband Optical Colours of Intermediate Redshift QSO Host Galaxiestical comparison between radio-loud and radio-quiet objects, we selected pairs of objects with approximately the same redshift and V-magnitude. Data was obtained in 1994 at the ESO NTT and at the Nordic Optical Telescope, primarily in the R band, but some of them also in V and/or I.
