Pulsars and Fast Transients (PFT) science with the MWA leverages high-time-resolution science capabilities developed around the voltage capture system (VCS) functionality, and the associated software sub-systems and processing pipelines. I will present an overview of the current capabilities around MWAX + VCSBeam, as well as select highlights from the past accomplishments, including the...
The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a `dying' pulsar, where radio emission ceases entirely. Here we report the discovery of a long-period pulsar, PSR J0452-3418, from the ongoing Southern-sky MWA Rapid Two-meter (SMART) pulsar survey.
The pulsar exhibits both sub-pulse drifting and...
Fast Radio Bursts (FRBs) are millisecond dispersed radio pulses of predominately extra-galactic origin. Despite hundreds of FRBs discovered at frequencies above 400 MHz, only a few were discovered below 400 MHz. One of the reasons is computational complexity of low-frequency FRB searches over wide fields of view (hundreds or thousands of square degrees) and long dispersion delays (of the order...
Millisecond pulsars (MSPs) are exquisite astrophysical tools which provide unique opportunities to advance fundamental physics. The MWA is playing an important role in preparing for SKA science, having recently completed data collection for the Southern-sky MWA Rapid Two-metre (SMART) pulsar survey. With a dwell time of 4800 s and high time/frequency resolutions, SMART will be the most...
