Gamma-ray Time Delay and Magnification Ratio in the Gravitationally-Lensed Blazar PKS 1830-211
S. Buson, M. De Toma, S. Larsson +7
We present the characterization of macrolensing properties of the gravitationally lensed system PKS 1830-211, utilizing data from the Fermi Large Area Telescope. While at gamma-ray…
Distortions in Periodicity Analysis of Blazars II: The Impact of Gaps
P. Peñil, N. Torres-Albà, A. Rico +4
Time series analysis is fundamental to characterizing the variability inherent in multi-wavelength emissions from blazars. However, a major observational challenge lies in the need…
Extensive Analysis of gamma-Ray Periodicity in Jetted AGN from the 4FGL Catalog Using Fermi-LAT Observations
P. Peñil, A. Domínguez, S. Buson +3
The quest to uncover periodic patterns within the -ray emissions of jetted active galactic nuclei (AGN) has recently emerged as a focal point in astrophysics. One of the primary…
Transient QPOs of Fermi-LAT blazars under the Curved Jet Model
P. Penil, J. Otero-Santos, A. Banerjee +4
This study explores transient quasi-periodic oscillations (QPOs) in the -ray emission of two blazars, PMN J05314827 and PKS 1502+106, using over a decade of Fermi Large Area…
Transient QPOs of Fermi-LAT blazars with Linearly Multiplicative Oscillations
P. Penil, J. Otero-Santos, A. Circiello +5
We present a study on the detection and characterization of transient quasi-periodic oscillations (QPOs) in the -ray emission of blazars 4C +31.03, MG1 J123931+0443, and PKS 162…
A Systematic Search for Spectral Hardening in Blazar Flares with the Fermi-Large Area Telescope
Adithiya Dinesh, Alberto Dominguez, V. Paliya +3
Blazars are a subclass of active galactic nuclei (AGN) that emit non-thermal radiation through relativistic jets, characterized by rapid flux and polarization variability. High syn…
