【 摘 要 】

The radio-loud active galactic nuclei having the radio emission arising from a core region rather than from lobes are often referred to as "blazars" and include Flat Spectrum Radio Quasars (FSRQ) and BL Lacertae (BL Lac) objects. During the period 1992 - 2015, SHALON has been used for observations of the metagalactic sources NGC1275, Mkn421, Mkn501, Mkn180, 3c382, 4c+31.63, OJ 287, 3c454.3, 4c+55.17, 1739+522. We present results of long term observations of FSRQ: among them are known object 3c454.3, high-red shifted quasar 1739+522 as well as BL Lac type objects. The observation results are presented with integral spectra, images and spectral energy distributions for each of sources at energies > 800 GeV. A number of variability periods in different wavelengths including VHE γ-rays were found.
