Résumé en anglais

Certain classes of astrophysical phenomena at high energies are known to be irregularly variable or of transient character, related to sources such as GRBs, AGN, or binary systems. Due to nonoptimized analysis schemes for transient searches at short timescales, some of those phenomena might have escaped proper characterization in the present H.E.S.S. analysis chains.In order to test the performance of our transient analysis capabilities, a module was developed to inject fake events into real data files. In that way a finite level of variability can be added to data from real sources to mimic characteristic variability patterns.Accordingly, this tool allows us to investigate the sensitivity limits of the analysis chains as a function of a variety of assumptions, such as different time profiles or spectral transitions, and to study performance and reliability for application in short-time transient searches with H.E.S.S.< Réduire
