Radio to gamma-ray variability study of blazar S5 0716+714

Understand

We present the results of a series of radio, optical, X-ray and gamma-ray observations of the BL Lac object S50716+714 carried out between April 2007 and January 2011.

• The multi-frequency observations were obtained using several ground and space based facilities.
• The intense optical monitoring of the source reveals faster repetitive variations superimposed on a long-term variability trend at a time scale of ~350 days.
• Episodes of fast variability recur on time scales of ~ 60-70 days.
