Constraining the PG 1553+113 binary hypothesis: interpreting hints of a new, 22-year period
Sagar Adhikari, Pablo Penil, John Ryan Westernacher-Schneider +5
PG 1553+113 is a well-known blazar exhibiting evidence of a -yr quasi-periodic oscillation (QPO) in radio, optical, X-ray, and -ray bands. Since QPO mechanisms often…
