Location of the Gamma-Ray Flaring Emission in the Parse-Scale Jet of the BL Lac Object AO 0235+164
Ivan Agudo, Alan P. Marscher, Svetlana G. Jorstad +12
We locate the gamma-ray and lower frequency emission in flares of the BL Lac object AO 0235+164 at >12pc in the jet of the source from the central engine. We employ time-dependent…
MAPCAT: Monitoring AGN with Polarimetry at the Calar Alto Telescopes
Ivan Agudo, Sol N. Molina, Jose L. Gomez +3
We introduce MAPCAT, a long-term observing program for "Monitoring of AGN with Polarimetry at the Calar Alto Telescopes". Multi-spectral-range studies are critical to understand so…
Multiwavelength Spectral Studies Of Fermi-LAT Blazars
Manasvita Joshi, Alan Marscher, Svetlana Jorstad +6
We present multiwavelength spectral analyses of two Fermi-LAT blazars, OJ 287 and 3C 279, that are part of the Boston University multiwaveband polarization program. The data have b…
Parsec-Scale Behavior of Blazars during High Gamma-Ray States
S. Jorstad, A. Marscher, I. Agudo +1
We compare the γ-ray light curves of the blazars, constructed with data provided by the Fermi Large Area Telescope, with flux and polarization variations in the VLBI core and brigh…
Optical Outburst of the Gamma-Ray Blazar S4 0954+658 in March-April 2011
V. M. Larionov, S. G. Jorstad, A. P. Marscher +5
We present optical photopolarimetric observations of the BL Lac object S4 0954+658 obtained with the 70-cm telescope in Crimea, 40-cm telescope in St.Petersburg, and 1.8-m Perkins…
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…
An Indirect Search for WIMPs in the Sun using 3109.6 days of upward-going muons in Super-Kamiokande
Kamiokande Collaboration, T. Tanaka, K. Abe +110
We present the result of an indirect search for high energy neutrinos from WIMP annihilation in the Sun using upward-going muon (upmu) events at Super-Kamiokande. Datasets from SKI…
The brightest gamma-ray flaring blazar in the sky: AGILE and multi-wavelength observations of 3C 454.3 during November 2010
S. Vercellone, E. Striani, V. Vittorini +84
Since 2005, the blazar 3C 454.3 has shown remarkable flaring activity at all frequencies, and during the last four years it has exhibited more than one gamma-ray flare per year, be…
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…
Multiwavelength Observations of the Gamma-Ray Blazar PKS 0528+134 in Quiescence
N. I. Palma, M. Boettcher
We present multiwavelength observations of the ultraluminous blazar-type radio loud quasar PKS 0528+134 in quiescence during the period July to December 2009. Significant flux vari…
Connection between the Accretion Disk and Jet in the Radio Galaxy 3C 111
Ritaban Chatterjee, Alan P. Marscher, Svetlana G. Jorstad +13
We present the results of extensive multi-frequency monitoring of the radio galaxy 3C 111 between 2004 and 2010 at X-ray (2.4--10 keV), optical (R band), and radio (14.5, 37, and 2…
AGILE detection of extreme gamma-ray activity from the blazar PKS 1510-089 during March 2009. Multifrequency analysis
F. D'Ammando, C. M. Raiteri, M. Villata +112
We report on the extreme gamma-ray activity from the FSRQ PKS 1510-089 observed by AGILE in March 2009. In the same period a radio-to-optical monitoring of the source was provided…
The first Fermi multifrequency campaign on BL Lacertae: characterizing the low-activity state of the eponymous blazar
A. A. Abdo
We report on observations of BL Lacertae during the first 18 months of Fermi-LAT science operations and present results from a 48-day multifrequency coordinated campaign from 2008…
