Particle diffusion and localized acceleration in inhomogeneous AGN jets. I. Steady-state spectra
(Oxford University Press, 2015)
We study the acceleration, transport, and emission of particles in relativistic jets. Localized stochastic particle acceleration, spatial diffusion, and synchrotron as well as synchrotron self-Compton (SSC) emission are ...
Synchrotron polarization in blazars
(IOP Publishing, 2014)
We present a detailed analysis of time- and energy-dependent synchrotron polarization signatures in a shock-in-jet model for γ-ray blazars. Our calculations employ a full three-dimensional radiation transfer code, assuming ...
Magnetic field amplification and flat spectrum radio quasars
(Oxford University Press, 2014)
We perform time-dependent, spatially resolved simulations of blazar emission to evaluate several flaring scenarios related to magnetic-field amplification and enhanced particle acceleration. The code explicitly accounts ...
Particle diffusion and localized acceleration in inhomogeneous AGN jets. II. Stochastic variation
(Oxford Univ Press, 2016)
We study the stochastic variation of blazar emission under a 2D spatially resolved leptonic jet model we previously developed. Random events of particle acceleration and injection in small zones within the emission region ...
Polarization swings reveal magnetic energy dissipation in blazars
(American Astronomical Society, 2015)
The polarization signatures of blazar emissions are known to be highly variable. In addition to small fluctuations of the polarization angle around a mean value, large (gsim180°) polarization angle swings are sometimes ...
Multiwavelength polarization as a diagnostic of blazar physics
(Sissa Medialab, 2015)
The nature of the high-energy emission in jet-dominated AGN (especially blazars) as well as the location and mode of acceleration of particles to ultra- relativistic energies are a matter of intensive debate. Both leptonic ...
