Description
We report on the discovery of multi-TeV gamma-ray pulsationsfrom PSR J1509-5850 with the H.E.S.S. array of imaging atmospheric Cherenkov telescopes. The light curve above 500 GeV is similar to the one obtained in the multi-GeV range with Fermi-LAT with no significant evolution with increasing energy.
The pulsed spectrum, as measured in the 500 GeV-10 TeV range, displays a hard index and is reminiscent of the spectrum of the Vela P2 pulse.
After the Crab and Vela pulsars, PSR J1509-5850 is the third one detected in the Very-High-Energy domain (>100 GeV) and the second one displaying a hard and multi-TeV spectral component. We will compare the properties of the two multi-TeV pulsars and discuss the implications for high energy emission models of pulsars.
