A New Measurement of the Extragalactic Background Light using 15\,yr of {\it Fermi}-Large Area Telescope Data
Anuvab Banerjee, Justin D. Finke, Marco Ajello +5
The extragalactic background Light (EBL) from ultraviolet to infrared comprises the emission from all stars, galaxies, and actively accreting black holes in the observable Universe…

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 16…

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…
