Testing and validating a transient event search pipeline using Murchison widefield array

Abstract

The pursuit of pulsar discovery is a continuously evolving field, offering prospects for daily advancements and ongoing enhancements. There are two types of pulse searches, one is a periodicity search and the other is single pulse search. Single pulse search techniques are sensitive to pulses such as those emitted by pulsars, Rotating Radio Transients (RRATs), and Fast Radio bursts (FRBs). The chances of these pulses being periodic becomes low. In addition to the randomness of the emission, the pulse flux densities can vary dramatically from pulse to pulse. This, accompanied by radio frequency interference considerations, complicates candidate identification and selection. Searching for single pulses from pulsars will help in studying unexplained phenomena like the complex pulse structure and nulling, all of which can be observed in a subpopulation of pulsars. Our objective is to analyse an existing pipeline for single pulse detection and maximize the identification of positive candidates while effectively filtering out noise for the Murchison Widefield Array.
