Scientific paper

Kes 75 is a composite SNR containing one of the most luminous pulsars and PWNe in the Galaxy. Early Chandra studies have identified an axisymmetric PWN structure, with knots of emission on either side of the pulsar. We find additional evidence for filaments and a jet at very faint levels. The SNR spectrum shows evidence for highly enhanced abundances of sulphur, but this is complicated by a hard spectral component associated, at least in part, with a grain scattering halo from the PWN. We propose a deep observation of Kes 75 in order to clearly resolve the newly-identified structures in the PWN, to map its spectrum, and to obtain sufficiently rich spectra to accurately determine the plasma conditions in the SNR shell in order to address the dynamical properties of the system.
