Pulsar Signal Processing

Last updated 4162 days ago by Russ Taylor

Teams at the University of British Columbia and McGill University are working on design of pulsar observing strategies and the time-based data acquisition and processing techniques to search for and measure rapid time variable signals from pulsars.  The SKA will have the capability to detected and study all of the tens of thousands of pulsar systems in the Milky Way Galaxy that are beamed toward the Earth, including pulsar-black hole binary systems.  These observations will have the potential to lead to entirely new tests of strong-field gravity.
