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...
متن کاملOptical Variability of the Quasar 3c 279: the Signature of a Decelerating Jet?
A recent optical monitoring campaign on the prominent quasar 3C 279 revealed at least one period of a remarkably clean exponential decay of monochromatic (BVRI) fluxes with time, with a time constant of τd = 12.8 d, over about 14 days. This is clearly too long to be associated with radiative cooling. Here we propose that this may be the signature of the deceleration of the synchrotron emitting ...
متن کاملDay-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands
Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and γ rays (CGRO/EGRET) for 1999 Jan–Feb and 2000 Jan–Mar. During both of those epochs the γ-ray levels were high, and all three observed bands demonstrated substantial variation, on time scales as short as one day. Correlation analyses provided no consistent pattern, although a rather significant optical/γ-ray correla...
