The connection between the parsec-scale radio jet and gamma-ray flares in the blazar 1156+295
Venkatessh Ramakrishnan, Jonathan León-Tavares, Elizaveta A. Rastorgueva-Foi +30
The blazar 1156+295 was active at gamma-ray energies, exhibiting three prominent flares during the year 2010. Here, we present results using the combination of broadband (X-ray thr…
Future mmVLBI Research with ALMA: A European vision
R. P. J. Tilanus, T. P. Krichbaum, J. A. Zensus +165
Very long baseline interferometry at millimetre/submillimetre wavelengths (mmVLBI) offers the highest achievable spatial resolution at any wavelength in astronomy. The anticipated…
Comprehensive Monitoring of Gamma-ray Bright Blazars. I. Statistical Study of Optical, X-ray, and Gamma-ray Spectral Slopes
Karen E. Williamson, Svetlana G. Jorstad, Alan P. Marscher +21
We present -ray, X-ray, ultraviolet, optical, and near-infrared light curves of 33 -ray bright blazars over four years that we have been monitoring since 2008 August with mul…
The Outburst of the Blazar S40954+658 in March-April 2011
D. A. Morozova, V. M. Larionov, I. S. Troitsky +22
We present the results of optical (R band) photometric and polarimetric monitoring and Very Long Baseline Array (VLBA) imaging of the blazar S4 0954+658, along with Fermi and gamma…
Evidence of internal rotation and a helical magnetic field in the jet of the quasar NRAO150
Sol N. Molina, Iván Agudo, José L. Gómez +3
The source NRAO150 is a very prominent millimeter to radio emitting quasar at redshift z=1.52 for which previous millimeter VLBI observations revealed a fast counterclockwise rotat…
MAGIC gamma-ray and multifrequency observations of flat spectrum radio quasar PKS 1510-089 in early 2012
MAGIC Collaboration, J. Aleksić, S. Ansoldi +218
Among more than fifty blazars detected in very high energy (VHE, E>100GeV) gamma-rays, only three belong to the subclass of Flat Spectrum Radio Quasars (FSRQs). MAGIC observed FSRQ…
