Spectral and spatial characteristics of PSR J1420-6047 nebula

Recently, HESS has revealed two sources of very high energy emission spatiallycoincident with the two pulsar wind nebulae of the Kookaburra complex. The TeVsource HESS J1420607 is coincident with the radio structure K3 associated tothe pulsar wind nebula powered by PSR J14206048. ASCA observations of the PWNhave revealed a clearly extended structure with a photon spectral index of 1.6apparently inconsistent with the steeper TeV spectrum, which probes lower energyelectrons. Recent Chandra observations showed a surprisingly faint compactstructure, although a faint arc is visible near the pulsar. We propose a deepXMM observation of the PWN of PSR J14206047 to determine its completemorphology, and fully characterize its spectrum along the nebula. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
