Study on temporal and spectral behaviour of 3C 279 during 2018 January flare

On the application of the mirror model for gamma-ray flare in 3C 279

Multiwavelength observations of high energy flare in 1996 from 3C 279 seems to favour the so called mirror model between different inverse Compton scattering models proposed as a possible explanation of gamma-ray emission in blazars. We performed kinematic analysis of the relativistic blob mirror system and found that only part of the mirror located very close to the jet axis (very likely insid...

Time 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...

Full 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...
