Fig. 5


Multiband lightcurve during the assumed scenario of density fluctuations along the jet axis explained in the text. The inset shows the definition of the snapshots during the first outburst in Fig. 6. The timescale of this flare corresponds to the synchrotron timescale of the electrons with a slight delay in the gamma rays caused by the cascades that need to be built up first. With a delay of about 4.28 days a second, orphan flare occurs in the VHEs when the freshly injected protons have been accelerated to high Lorentz factors to radiate efficiently. The timescale here corresponds to the synchrotron loss timescale of protons.
