Description
The physical processes behind unobservable activities in cosmic accelerators can be uniquely studied through the investigation of temporal variability exhibited by extreme astrophysical objects. These variations could be tied to the nature of the parent particle population, leptonic or hadronic, changes in the field strength or particle acceleration in the emission zone, to the precession of collimated relativistic plasma, among others.
Studying the variable emission from gamma-ray cataloged sources can be challenging, since generating mission-long well-sampled light curves is computationally expensive. In this contribution, we make use of the publication-quality, mission-long, continuously updated Fermi-LAT Light Curve Repository data to circumvent this issue, validate it, and extract variability features such as duty cycles, flare duration and baseline behaviors. We present our findings on the characteristics of these flares according to the source type.
