Very High Energy gamma-ray transient events with HAWC and H.E.S.S.

Transient events are some of the most challenging scenarios to explore in Very High Energy Gamma-Ray Astronomy. These events come from extremely rare and violent processes where great quantities of energy are emitted in a matter of milliseconds up to hours. The importance of the observation and quantification of these phenomena lies in the fact that they can constrain and verify the existing models of non-thermal mechanisms related to the expected emission of particles at high energies. In general, given their extragalactic origin, the detection can be used for studying the Extragalactic Background Light absorption, for the measurement of cosmological parameters and for explaining the formation of heavy chemical elements.

Imaging Atmospheric Cherenkov Telescopes such as H.E.S.S, and Water Cherenkov Observatories, like HAWC, present different advantages and challenge for the observation of transients events. On the one hand, H.E.S.S has a low energy threshold and high sensitivity, the small field of view, short operational time and repointing speed to transient alerts require careful optimisations for the observations. On the other hand, despite the advantage of continuous operation and a large instantaneous field of view, HAWC is limited by the background rejection and a lower sensitivity for the GeV energy regime. My PhD work is focused on the improvement and development of analysis and detection tools that can take me to exploit the best of both experiments for the observation and scientific analysis of these highly pursued events.
