متن کامل4-year optical-infrared photometric and polarimetric behaviors of a gamma- ray blazar 3C 454.3
We have performed a multi-color photo-polarimetric monitoring of 45 optical-bright blazars since 2007. 3C 454.3, which is one of the brightest blazars in the gamma-ray sky, is one of targets of its project. We have made photo-polarimetric monitorings since July 2007. The object showed violent variation in its flux and polarization. In particular, four large-amplitude outbursts in 2007, 2008, 20...
متن کاملThe Complex VHE And Multiwavelength Flaring Activity
The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. Given the strong broad line region emission defining this blazar class, and the resulting high optical depth for VHE (E > 100 GeV) γ-rays, it was surprising to detect VHE emissio...
متن کاملTime Variable Faraday Rotation Measures of 3c 273 & 3c 279
Multifrequency polarimetry with the VLBA confirms the previously reported timevarying Faraday rotation measure (RM) in the quasar 3C 279. Variability in the RM and electric vector position angle (EVPA) of the jet component (C4) is seen making it an unreliable absolute EVPA calibrator. 3C 273 is also shown to vary its RM structure on 1.5 year time-scales. Variation in the RM properties of quasar...
متن کاملFull Polarization Spectra of 3c 279
We report the results of parsec-scale, multi-frequency VLBA observations of the core region of 3C 279 in Stokes I, linear polarization, and circular polarization. These full polarization spectra are modeled by radiative transfer simulations to constrain the magnetic field and particle properties of the parsec-scale jet in 3C 279. We find that the polarization properties of the core region, incl...
