Parkes observations for project P535 semester 2006APRS

A combination of Parkes and GMRT can provide polarization, single pulse, and other information for about 200 pulsars from frequencies between 0.15 and 8~GHz.\n\nWe aim to obtain:\n(i)Polarization profiles at high time resolution in at least 6\nobserving bands, with absolute position angle calibration.\n(ii)The spectral behaviour of a large sample of pulsars over a wide frequency range.\n(iii)An unbiased survey for pulsars with peculiar single pulse\nbehaviour such as microstructure, drifting subpulses and nulling.\n(iv)Scintillation parameters, RMs and DMs for the sample.\n\nThe science questions we want to address are:\nWhat are the causes of deviations from the rotating vector model (RVM)?\nWhat is the origin of circular polarization?\nWhat does the behaviour of individual pulse components tell us about the structure of emission beam?\nIs microstructure caused by refractive effects in the pulsar magnetosphere?\nWhat is the location of the flux-density turnover frequency and what\nits dependence (if any) on pulsar parameters?\n\nImprovement of our understanding of the pulsar emission mechanism not only advances our knowledge on this unsolved astrophysical problem, it is also essential for the ongoing exploitation of pulsars as elements of grand experiments in physics.
