The Radio Jets and Accretion Disk in NGC 4261
D. L. Jones, A. E. Wehrle, D. L. Meier +1
The structure of AGN accretion disks on sub-parsec scales can be probed through free-free absorption of synchrotron emission from the base of symmetric radio jets. We present new V…
VSOP and Ground-based VLBI Imaging of the TeV Blazar Markarian 421 at Multiple Epochs
B. G. Piner, S. C. Unwin, A. E. Wehrle +3
We present thirty VLBI images of the TeV blazar Markarian 421 (1101+384) at fifteen epochs spanning the time range from 1994 to 1997, and at six different frequencies from 2.3 to 4…
Observations of OJ 287 from the Geodetic VLBI Archive of the Washington Correlator
C. E. Tateyama, K. A. Kingham, P. Kaufmann +3
We present 27 geodetic VLBI maps of OJ 287 obtained from the archive of the Washington correlator. The observations presented here were made between 1990 October and 1996 December.…
