Multi-waveband Emission Maps of Blazars
Alan Marscher, Svetlana G. Jorstad, Valeri M. Larionov +2
We are leading a comprehensive multi-waveband monitoring program of 34 gamma-ray bright blazars designed to locate the emission regions of blazars from radio to gamma-ray frequenci…
Radio Flaring Activity of 3C 345 and its Connection to Gamma-ray Emission
F. K. Schinzel, A. P. Lobanov, S. G. Jorstad +3
3C 345 is one of the archetypical active galactic nuclei, showing structural and flux variability on parsec scales near a compact unresolved radio core. During the last 2 years, th…
Location of gamma-ray Flare Emission in the Jet of the BL Lacertae Object OJ287 more than 14pc from the Central Engine
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +18
We combine time-dependent multi-waveband flux and linear polarization observations with sub-milliarcsecond-scale polarimetric images at lambda=7mm of the BL Lacertae-type blazar OJ…
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
LAT collaboration, A. A. Abdo et al., the VERITAS collaboration +4
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GA…
Another look at the BL Lacertae flux and spectral variability
C. M. Raiteri, M. Villata, L. Bruschini +52
The GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT) monitored BL Lacertae in 2008-2009 at radio, near-IR, and optical frequencies. During this period,…
The Megaparsec-Scale X-ray Jet of the BL Lac Object OJ287
Alan P. Marscher, Svetlana G. Jorstad
We present an X-ray image of the BL Lacertae object OJ287 revealing a long jet, curved by 55 degrees and extending 20", or 90 kpc from the nucleus. This de-projects to >1 Mpc based…
