Parsec-Scale Jets and Tori in Seyfert Galaxies
A. L. Roy, J. M. Wrobel, A. S. Wilson +6
What causes the dichotomy between very powerful and very weak radio emission from AGNs? Perhaps the engines are the same but the jets get disrupted by dense ISM in radio-quiet obje…
Blazars in Low-Luminosity and Radio-Weak AGN?
Heino Falcke, Sera Markoff, Peter L. Biermann
Typical blazars seem to be associated with FR I and FR II radio galaxies and radio-loud quasars. However, what happens at lower powers? Do blazars exist in low-luminosity AGN or do…
A jet model for the broadband spectrum of XTE J1118+480: Synchrotron emission from radio to X-rays in the Low/Hard spectral state
Sera Markoff, Heino Falcke, Rob Fender
Observations have revealed strong evidence for powerful jets in the Low/Hard states of black hole candidate X-ray binaries. Correlations, both temporal and spectral, between the ra…
III Zw 2: superluminal expansion and compact lobe expansion in a Seyfert galaxy
A. Brunthaler, H. Falcke, G. C. Bower +3
So far, all relativistically boosted jets with superluminal motion have only been detected in typical radio galaxies with early type host galaxies. We have now discovered superlumi…
Radio-Variability in Radio-Quiet Quasars and Low-Luminosity AGN
Heino Falcke, Joseph Lehar, Richard Barvainis +2
We report on two surveys of radio-weak AGN to look for radio variability. We find significant variability with an RMS of 10-20% on a timescale of months in radio-quiet and radio-in…
Radio Sources in Low-Luminosity Active Galactic Nuclei. II. VLBI Detections of Compact Radio Cores and Jets in a Sample of LINERs
Heino Falcke, Neil M. Nagar, Andrew S. Wilson +1
We have used the VLBA at 5 GHz to observe all galaxies with nuclear radio flux densities above 3.5 mJy found in a VLA survey at 15 GHz of a sample of nearby LINER galaxies. All gal…
