摘要：

Electrons emitting nonthermal photons in blazars are possibly accelerated by turbulences developed in jets. In this paper, we consider the case of so-called hard-sphere scattering as an interaction model between turbulences and electrons, in which the acceleration timescale is independent of the electron energy. We numerically simulate broadband emission from blazar jets with a one-zone time-dependent code, taking into account the turbulence acceleration. Our model reproduces various blazar spectra with simple assumptions, such as constant particle injection rate, constant diffusion coefficient, and conical geometry of the jet. We also discuss possible mechanisms to realize the hard-sphere-like acceleration in blazar jets.
