Systematic Search for Long-Term Trends in Fermi-LAT Jetted Active Galactic Nuclei
P. Penil, A. Domínguez, S. Buson +3
Jetted Active Galactic Nuclei (AGN) exhibit variability across a wide range of time scales. Traditionally, this variability can often be modeled well as a stochastic process. Howev…
