Parkes observations for project P427 semester 2009APRS

Timing the dozen pulsars discovered in P303 is ensuring high quality results: (a) the peculiarities (in position or projected acceleration) of all the 5 millisecond pulsars in NGC6752 suggested the presence of non thermal dynamics in the core, perhaps due to black-holes of intermediate mass; (b) the eclipsing pulsars in NGC6397 and NGC6266 are primary targets for studying the late evolution of exotic binaries. We propose to continue our timing project focusing mostly on NGC6752 at 20cm (in order to measure additional parameters useful to constrain the existence of a black-hole), NGC6397 at 10cm (for studying the eclipse region and the orbital secular evolution) and NGC6266 at 20cm (for investigating the cluster's proper motion and dynamics and the eclipsing pulsar). We also request time for performing pilot observations for a new deeper than ever search for millisecond pulsars in a subset of suitable clusters. This revamped search will exploit the new back-ends (APSR and DFB4) now available at Parkes.
