H.E.S.S. Observations of the Crab during its March 2013 GeV Gamma-Ray Flare

Understand

Context.

• On March 4, 2013, the Fermi-LAT and AGILE reported a flare from the direction of the Crab Nebula in which the high-energy (HE; E > 100 MeV) flux was six times above its quiescent level.
• Simultaneous observations in other energy bands give us hints about the emission processes during the flare episode and the physics of pulsar wind nebulae in general.
• Aims.
