We compare the extrapolated epochs of zero separation of apparent superluminal components from the cores in γ-ray bright blazars with the EGRET light curves. In 10 out of 20 superluminal components with sufficient γ-ray data, the epochs of zero separation coincide with times of global or local maxima of the γ-ray light curves within the 1-σ uncertainties of the epochs of zero separation. If we focus only on the γ-ray peaks, nine out of ten with sufficient VLBA data are accompanied by superluminal ejections. The γ-ray flares are therefore associated with energetic events in the jets rather than with minor episodes of enhanced particle acceleration. © 2000 American Institute of Physics.

    During the EGRET era some correlations between γ-ray and radio properties of blazars were discovered: the highest apparent speeds occur in γ-ray blazars and a connection exists between ejections of superluminal components and high states of γ-ray emission. We discuss the strategy of...

    Our earlier joint analysis of light curves for the blazar 0059+581 at 4.8, 8, 14.5, 22, and 37 GHz with high-resolution VLBI images led us to suggest that the activity in this source develops in cycles, or periods, with a duration of about four years, with a “typical scenario” for...

    The current status of leptonic jet models for gamma-ray blazars is reviewed. Differences between the quasar and BL-Lac subclasses of blazars may be understood in terms of the dominance of different radiation mechanisms in the gamma-ray regime. Spectral variability patterns of different blazar...

    Measurements of the flux of very-high-energy (>1 TeV) gamma rays from the blazar 3C 66A obtained over four years are presented. The mean flux over the four-year period was (2.8 ± 0.4) × 10[sup –11] cm[sup –2] s[sup –1]. There is a correlation between the...

    Published EGRET spectra from blazers extend only to 10 GeV, yet EGRET has detected approximately 2000 γ-rays above 10 GeV of which about half are at high Galactic latitude. We report a search of these high-energy γ-rays for associations with the EGRET and TeV detected blazers. Because the...

    We present the results of VLBI Space Observatory Program (VSOP) observations of the gamma-ray blazar 3C 279 at 1.6 and 5 GHz from January 1998. The combination of the VSOP and VLBA-only images at these two frequencies maps the jet structure on scales from 1 to 100 mas. A spectral index map was...

    BL Lacertae is a nearby active galaxy of the blazar class with a redshift z=0.069 and therefore, within the unified model of AGN, a candidate for the observation of gamma emissions in the TeV range. During 1998, BL Lacertae has been observed by the HEGRA equatorial mount Cherenkov telescope. The...
