| Abstract: | The on-going Parkes multibeam survey has been astoundingly successful (Manchesteret al. 2001), and its discovery of over 600 pulsars has opened up new avenues for probing the Galaxy’s electron content and magnetic
field. Here we report on recent observations made with the Arecibo 305-m telescope, where 80 distant, high dispersion measure
pulsars (of which 35 are from the multibeam survey) were studied at multiple frequency bands in the range 0.4–2.4 GHz, in
order to determine their scattering properties, rotation measures and spectral indices. The results will be used to meet a
variety of science goals; viz., creating an improved model of the electron density, mapping out the Galactic magnetic field,
and modeling the pulsar population. |
