Sub-parsec scale imaging of Centaurus A
Cornelia Müller, M. Kadler, R. Ojha +6
At a distance of about 3.8 Mpc, the radio galaxy Centaurus A is the closest active galaxy. Therefore it is a key target for studying the innermost regions of active galactic nuclei…
The gamma-ray properties of radio-selected extragalactic jets
M. Boeck, M. Kadler, G. Tosti +4
Most extragalactic jets in radio-loud Active Galactic Nuclei are bright and variable gamma-ray sources, which are continuously monitored with Fermi/LAT. We present the gamma-ray pr…
VLBI Monitoring of the bright gamma-ray blazar PKS 0537-441
Faith Hungwe, Roopesh Ojha, Matthias Kadler +6
One of the defining characteristics of BL Lacertae objects is their strong variability across the electromagnetic spectrum. PKS 0537-441 is one such object and is one of the most l…
TANAMI: Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry I. First-Epoch 8.4 GHz Images
Roopesh Ojha, Matthias Kadler, Moritz Böck +24
We introduce the TANAMI program (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) which is monitoring an initial sample of 43 extragalactic jets located…
Multiwavelength campaign of the gamma-ray flaring source PKS 2052-47
C. S. Chang, E. Ros, M. Kadler +4
The flat-spectrum radio quasar PKS 2052-47 experienced an optical flare in July-August, 2009. On August 9, the LAT detector onboard Fermi observed a flare from the source, which re…
