A multi-wavelength polarimetric study of the blazar CTA 102 during a Gamma-ray flare in 2012
Carolina Casadio, José L. Gómez, Svetlana G. Jorstad +28
We perform a multi-wavelength polarimetric study of the quasar CTA 102 during an extraordinarily bright -ray outburst detected by the {\it Fermi} Large Area Telescope in Septemb…
Multiwavelength behaviour of the blazar OJ 248 from radio to γ-rays
M. I. Carnerero, C. M. Raiteri, M. Villata +4
We present an analysis of the multiwavelength behaviour of the blazar OJ 248 at z = 0.939 in the period 2006-2013. We use low-energy data (optical, near-infrared, and radio) obtain…
Simultaneous multifrequency radio observations of the Galactic Centre magnetar SGR J1745-2900
P. Torne, R. P. Eatough, R. Karuppusamy +12
We report on simultaneous observations of the magnetar SGR J1745-2900 at frequencies to using the Nancay 94-m equivalent, Effelsberg 100-m, and IRAM 30-m…
The awakening of BL Lacertae: observations by Fermi, Swift, and the GASP-WEBT
C. M. Raiteri, M. Villata, F. D'Ammando +4
Since the launch of the Fermi satellite, BL Lacertae has been moderately active at gamma-rays and optical frequencies until May 2011, when the source started a series of strong fla…
Multiwavelength Intraday Variability of the BL Lac S5 0716+714
Alok C. Gupta, T. P. Krichbaum, P. J. Wiita +31
We report results from a 1 week multi-wavelength campaign to monitor the BL Lac object S5 0716+714 (on December 9-16, 2009). In the radio bands the source shows rapid (~ (0.5-1.5)…
Gamma-ray Flaring Emission in Blazar OJ287 Located in the Jet >14 pc from the Black Hole
I. Agudo, S. G. Jorstad, A. P. Marscher +8
We combine the Fermi-LAT light curve of the BL Lacertae type blazar OJ287 with time-dependent multi-waveband flux and linear polarization observations and submilliarcsecond-scale p…
Gamma-ray emission region located in the parsec scale jet of OJ287
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +8
We report on the location of the gamma-ray emission region in flares of the BL Lacertae object OJ287 at >14pc from the central supermassive black hole. We employ data from multi-sp…
On the Location of the Gamma-ray Emission in the 2008 Outburst in the BL Lacertae Object AO 0235+164 through Observations across the Electromagnetic Spectrum
Ivan Agudo, Alan P. Marscher, Svetlana G. Jorstad +38
We present observations of a major outburst at centimeter, millimeter, optical, X-ray, and gamma-ray wavelengths of the BL Lacertae object AO 0235+164. We analyze the timing of mul…
Flaring Behavior of the Quasar 3C~454.3 across the Electromagnetic Spectrum
Svetlana G. Jorstad, Alan P. Marscher, Valeri M. Larionov +29
We analyze the behavior of the parsec-scale jet of the quasar 3C~454.3 during pronounced flaring activity in 2005-2008. Three major disturbances propagated down the jet along diffe…
