Profile Analysis of the Multiwavelength 2.1-year Oscillations of PG 1553+113

P. Peñil, N. Torres-Albà, A. Rico +5

We investigate the morphology of the oscillation profiles of the blazar PG~1553+113 in relation to its well-known $\sim$2.1 yr periodicity. We identify individual cycles in the $\gamma$…
