Giant Pulses from J1752+2359

Recently the pulsar J1752+2359 was found to b e among the small group of pulsars which emit o ccasional "giant pulses", which are much stronger than the average pulse or the typical single pulse. This group of pulsars (which includes the Crab Nebula pulsar) offers a unique opp ortunity to study the emission physics of pulsars via high time resolution observations. The availability of this second "slow" pulsar for study with high time resolution is invaluable to our ongoing program to distinguish b etween theoretical mo dels of pulsar emission. We prop ose a set of observations of J1752+2359 at 327, 1425, and 2650 MHz at high time resolution to extend our previous work by comparing the temp oral b ehavior of this pulsar with our micro- and nanostructure measurements of the Crab giant pulses.
