Living life on the edge - Wide-field VLBI at 90 cm!
Emil Lenc, Mike A. Garrett, Olaf Wucknitz +2
We report on a recent 90 cm wide-field VLBI survey of two 3.1 deg^2 fields using the VLBA, Westerbork and Jodrell Bank telescopes. In-beam calibration was used to calibrate each fi…

The Size of the Radio-Emitting Region in Low-luminosity Active Galactic Nuclei
James M. Anderson, James S. Ulvestad
We have used the VLA to study radio variability among a sample of 18 low luminosity active galactic nuclei (LLAGNs), on time scales of a few hours to 10 days. The goal was to measu…

Low-Luminosity AGNs at the Highest Resolution: Jets or Accretion Flows?
James M. Anderson, James S. Ulvestad, Luis C. Ho
Six low-luminosity active galactic nuclei have been imaged at multiple frequencies from 1.7--43 GHz (2.3--15 GHz for three of the galaxies) using the Very Long Baseline Array. In s…
