Analytical and numerical time-dependent modelling of SSC blazars variability
نویسنده
چکیده
A time-dependent synchrotron self-Compton (SSC) leptonic model, developed with some analytical formulations and a numerical code is summarized. This SSC emission model, developed with some analytical formulations and a numerical code, allow to investigate quantitatively the multiwavelength spectral variability of blazars, providing estimates for physical parameters and the bolometric power. The temporal evolution of the electron distribution in a relativistic plasma blob with isotropic magnetic field, is calculated resolving numerically a first order kinetic equation with a fast semi-implicit finite differences scheme derived from a more general solving scheme suitable for diffusion-advection Fokker-Planck equations. The model provides time-dependent synchrotron and inverse Compton emissivities and spectral energy distributions, incorporating radiative cooling as well as light crossing time effects and the relativistic beaming.

A multi-zone model for simulating the high energy variability of TeV blazars
We present a time-dependent multi-zone code for simulating the variability of Synchrotron-Self Compton (SSC) sources. The code adopts a multi-zone pipe geometry for the emission region, appropriate for simulating emission from a standing or propagating shock in a collimated jet. Variations in the injection of relativistic electrons in the inlet propagate along the length of the pipe cooling rad...
متن کاملEnergy-dependent variability in blazars SSC simulations
The light curves of blazars have been studied from radio wavelengths up to very high energy gamma-rays, and their statistical properties seem to be often compatible with a red noise process, where variability power decreases with increasing frequency. An increase of light curve variance with energy has been reported by some authors. In order to reproduce the statistical properties of a blazar l...

One-zone radiation models have been widely used in modelling the steady-state multiwavelength (MW) spectra of blazars, having as main goal the determination of the physical conditions in the emitting region, such as the magnetic field strength, the species of radiating particles etc. Then, the results from onezone stationary modelling are often used as a stepping stone for studying flaring even...

Nearly simultaneous multiband monitoring of blazars is very limited and most studies reported in literature are conflicting, too. Although optical variability on intra-night timescales is now a well established phenomenon for blazars, its relationship to long-term variability remains unclear. Possible clues could come from monitoring the optical spectrum for correlation with brightness. The pr...
