Title of the communication: VLBI Images of Gamma-Ray Bright Blazars
Preliminary abstract (12 lines max.):
The author, with A.E. Wehrle and W. Xu (IPAC), J. Mattox (Boston U.), and S. Bloom (NASA/GSFC), has observed roughly 40 of the EGRET detected blazars with the VLBA at 22 and 43 GHz (some at 8.4 GHz as well), starting in Nov 1993. For many of these objects, we have data obtained at two or more epochs. The most interesting images will be shown. Some of the blazars have prominent jets, while others show only faint secondary components or no non-core structure at all. We intend to continue the project for 1-2 more years so that we can measure the apparent velocities of separation of the knots from the cores.
