Scientific paper

During 1990-1991 more than two dozens of extragalactic objects were observed by X-ray instruments aboard the Granat satellite. Among them there were active galactic nuclei (AGNs) and Seyfert galaxies (NGC4151, NGC5548, MCG-30-15, IC4329, etc.), quasars (3C273, 3C390.3, etc.), radio galaxies (Cen A, M87, etc.) and clusters of galaxies (Virgo, Perseus, Coma, etc.). We will discuss below the preliminary results obtained with the ART-P telescope during the observations of five sources: NGC4151, 3C273, Cen A and the galaxies M87 and NGC4388 in the Virgo cluster.
