Total Time Requested: 30 Hours
Proposal Title: Probing the Local ISM with pulsars: the North Polar Spur and the GSH
238+00+09 superbubble
ABSTRACT:
We will measure the scintillation properties for a selected sample of pulsars that probe the regions toward two
prominent features in the local interstellar environment: the North Polar Spur (the brightest section of radio Loop
I) and GSH 238+00+09, a nearby superbubble toward l  238 ф . For the latter, we will also study a similar sample
of southern objects with the Giant Metre-wave Radio Telescope. In addition, we will study a smaller sample of
objects in a complementary part of the sky (Quadrant 1). These measurements, along with the existing ones, will
be used to furnish a more realistic picture of the distribution of scattering plasma in the Local Interstellar
Medium. We will make observations at 430 and 327 MHz, with the PSPM and possibly the WAPP. Our source list
is spread over the 5{22 hr RA range, and we request a total of 30 hr of telescope time, split into multiple observing
sessions.
