An explanation for 13 consecutive day activities of Mrk 421

It is surprising to find a fact for migration in the peak positions of synchrotron spectra energy distribution component during activity epochs Mrk 421, accompanying with an orphan flaring at X-ray and GeV-TeV $\gamma$-ray bands. A geometric interpretation standard shock or stochastic acceleration models blazar emission have difficulty reproducing these observed behaviours. The present paper introduces linear by integrating reconnection electric field into particle transport model behaviours 421. We note that strong evidence evolution multi-wavelength spectral characteristic shifting frequency, bands provides important electrostatic diagnostic jet. Assuming suitable parameters, we apply results simulation 13-day event 2010 March concentrating on frequency. clear ratio magnetic strength plays role temporal frequency component. suggest responsible reasonable. Based results, issue may denote temporary blazars, rather than permanent one.
