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.

We aim to obtain:
(i)Polarization profiles at high time resolution in at least 6
observing bands, with absolute position angle calibration.
(ii)The spectral behaviour of a large sample of pulsars over a wide frequency range.
(iii)An unbiased survey for pulsars with peculiar single pulse
behaviour such as microstructure, drifting subpulses and nulling.
(iv)Scintillation parameters, RMs and DMs for the sample.

The science questions we want to address are:
What are the causes of deviations from the rotating vector model (RVM)?
What is the origin of circular polarization?
What does the behaviour of individual pulse components tell us about the structure of emission beam?
Is microstructure caused by refractive effects in the pulsar magnetosphere?
What is the location of the flux-density turnover frequency and what
its dependence (if any) on pulsar parameters?

Improvement 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.
