PG~1553+113 is the blazar with the most-significantly detected periodic patter in its multiwavelength (MWL) emission, making it one of the most promising candidates for hosting a s…
Coexistence of Chromatic Flares and an Achromatic QPO in the Gamma-ray Blazar PG 1553+113
Elena Madero, Alberto Domínguez
The physical origin of quasi-periodic oscillations (QPOs) in blazars remains debated, with geometric and plasma-driven scenarios as the main competing interpretations. Discriminati…
