Proposal Type: Regular
General Category: Pulsars
Observation Category: Galactic
Total Time Requested: 28 Hours
Proposal Title: Probing the Galaxy's Electron Content and Magnetic Field Using Newly Discov-
ered Pulsars
ABSTRACT:
We will determine the scattering properties, rotation measures, and spectral indices of recently discovered pulsars
in a narrow but deep region in the rst quadrant of the Galaxy. The scattering measurements will be used to create
an improved model of the interstellar electron density. The rotation measures will be used to map out the Galactic
magnetic eld. Spectral index measurements will be useful in modeling the pulsar population and in determining
future directions for pulsar searches. This proposal is a continuation of projects P1423 and P1427.
