Radio to gamma-ray variability study of blazar S5 0716+714
(EDP Sciences, 2013)
We present the results of a series of radio, optical, X-ray, and γ-ray observations of the BL Lac object S50716+714 carried out between April 2007 and January 2011. The multifrequency observations were obtained using several ...
How gravitational lensing helps y-ray photons avoid y-y absorption
(IOP Publishing, 2014)
We investigate potential γ – γ absorption of γ-ray emission from blazars arising from inhomogeneities along the line of sight, beyond the diffuse Extragalactic Background Light (EBL). As plausible sources of excess γ – γ ...
