General Category: Pulsars
Observation Category: Galactic
Total Time Requested: 30 Hours
Proposal Title: Probing the Interstellar Electron Density with New Parkes Multibeam Survey
ABSTRACT:
We propose to measure pulse-broadening times for 45 newly discovered pulsars from the Parkes multibeam survey
that can be observed at Arecibo. This is part of a large-scale project being undertaken in collaboration with pulsar
groups at JBO, ATNF and NCRA, and we will use Parkes and GMRT to obtain similar data for pulsars in the
Southern sky. The upgraded Arecibo, along with the spectrometer capabilities of AOFTM and WAPP, will allow
us to obtain high quality pulse proles with minimal dispersion and instrumental eects. This data set, and similar
ones from Parkes and GMRT, will provide essential inputs for a detailed and sophisticated modeling of interstellar
electron density in the inner Galaxy. We seek to obtain pulse-broadening measurements at 430 MHz and 610 MHz,
and observations at higher frequencies (1.4 or 2.2 GHz) for information on the intrinsic pulse shapes. We request 30
hours of telescope time in total, split up into multiple observing sessions.
