Gamma-ray quasi-periodicities of blazars. A cautious approach
Stefano Covino, Angela Sandrinelli, Aldo Treves
The availability of about a decade of uninterrupted sky monitoring by the Fermi satellite has made possible to study long-term quasi-periodicities for high-energy sources. It is th…
Pulsar Timing Constraints on the Fermi Massive Black-Hole Binary Blazar Population
A. Miguel Holgado, Alberto Sesana, Angela Sandrinelli +4
Blazars are a sub-population of quasars whose jets are nearly aligned with the line-of-sight, which tend to exhibit multi-wavelength variability on a variety of timescales. Quasi-p…
Quasi-periodicities of BL Lac Objects
Angela Sandrinelli, Stefano Covino, Aldo Treves +4
We review the reports of possible year-long quasi-periodicities of BL Lac objects in the -ray and optical bands, and present a homogeneous time analysis of the light curves of P…
