Scientific paper

The TeV source HESS J1420-607 is coincident with the Kookaburra's northern radio wing, and is most probably associated to the pulsar wind nebula (PWN) powered by the high spin-down pulsar PSR J1420-6048. It is extended along the radio structure and has a flux of about 0.1 Crab. ASCA observations of the PWN have revealed a 6' extended structure with a photon spectral index of 1.6 apparently inconsistent with the steeper TeV spectrum, which probes lower energy electrons. Here, we propose a deep XMM observation of the PWN of PSR J1420-6047 to have a complete multiwavelength determination of its morphology, in particular reveal the compact nebula and the nebula trail, and characterize its pectrum over the whole nebula extent to check the association with the TeV source.
