Exploring Precision Timing of Millisecond Pulsars with Wide-Bandwidth Observations

This thesis studies the masses, velocities, and interstellar medium effects of rapidly spinning neutron stars called millisecond pulsars. The masses of seven pulsars and their binary companions are measured. A large sample of millisecond pulsar velocities were measured and their distributions in the galaxy were analysed. The random variations in the electron density towards these millisecond pulsars were analysed for their consistency between measurement methods between observations conducted at two telescopes. The thesis also presents RFIHunter for excising interference from radio pulsar observations. These studies enhance our understanding of fundamental physics of pulsars and the Milky Way kinematics, and will benefit astronomers.
