Flares at different wavelengths. (a) Flare in a self-absorbed region. The parameters have the following values: cm, G, erg s⁻¹, , u_exp = 0.1 c, γ_min = 1, γ_max = 10⁶, p = 2, δ = 10, and z₀ = 0.001 pc. The magnetic field decreases as B′∝R^{′ − 1} and the electron luminosity as . For the γ-ray flare, we used a pulse which was injected at , with a width w′ = 50 t_cross, 0 and α = 45. The dashed lines represent the emission of the blob without the reaccelerating episode; (b) flare in an optically thin region. In this case, we change only the initial electron luminosity erg s⁻¹ and the reaccelerating episode occurs at the time, , the rest of the parameters are the same as in case (a).
