Abstract:
Observations of the Galactic Plane performed by the H.E.S.S. telescope array
have revealed a significant excess at very-high-energies (VHE; E>0.1 TeV) from
the direction of PSR J1459-60, a rather old gamma-ray pulsar (64 kyr) with a
spindown energy of ~10^36 erg/s, discovered by the Fermi/LAT satellite in
high-energy (HE) gamma-rays. The X-ray pulsar counterpart has been recently
detected using the Suzaku satellite. In this contribution, we present the
discovery of a new VHE gamma-ray source, including morphological and spectral
analyses. Its association with the gamma-ray pulsar in a PWN scenario will be
discussed.
