A Geometric Model to Interpret the γ-Ray Quasiperiodic Oscillation of PG 1553+113

A Geometric Model to Interpret the γ-Ray Quasiperiodic Oscillation of PG 1553+113

We propose a jet helical motion model to explain the γ -ray quasiperiodic oscillation of PG 1553+113. In this model, we hypothesize that a relativistic jet with constant angular velocity rotates around the axis, causing the Doppler factor of the jet to vary over time, leading to periodic changes in...
