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 2.1 yr periodicity. We identify individual cycles in the …

Morphology-aware periodicity searches in Fermi-LAT blazars
Aaron A. Maldonado, Alberto Domínguez, Adithiya Dinesh +4
Standard periodicity searches in active galactic nuclei assume sinusoidal modulation, whereas gamma-ray blazar emission often features asymmetric flares and localized bursts. We in…

Gamma-Ray Periodicity in Jetted AGN: Revisiting Periodicity Candidates with >17 years of Fermi-LAT Data
P. Peñil, A. Rico, A. Domínguez +3
We reanalyze previously reported gamma-ray periodicity candidates in jetted active galactic nuclei using more than 17 years of Fermi-LAT observations. The updated data provide a ro…
