Pulse Signal Simulation of Pulsars
Abstract
The present thesis is a work in progress on improving the simulation of integrated pulse profiles of pulsars. Pulsars, highly magnetized rotating neutron stars, serve as precise cosmic clocks useful for studying gravity and the interstellar medium. Although periodic pulses from many pulsars are observed and modeled at differ- ent radio frequencies, a robust realistic simulation of their profiles utilizing their parameters remain underdeveloped. The present study focuses on developing a physically consistent model to reproduce observed pulse shapes across multiple frequencies. This study will be useful in coherently understanding the various as- pects of the pulsar emission mechanism. These integrated pulse profiles are the time-averaged properties of pulsar emission and are obtained after averaging indi- vidual pulses over a few thousand rotations. Observed to be highly stable, these are indicative of the global properties of the pulsar magnetosphere. By refining simulation techniques and incorporating the propagation effects of the interstellar medium, this work will prove to be helpful in generating synthetic, yet realistic models. The results are expected to contribute to the interpretation of observa- tional data and to the development of improved timing and emission models for pulsars
