Abstract: Pulsars and Fast Radio Bursts (FRB) are some of radio astronomy's most energetic and "fast" objects. They are both possibly from "neutron stars." In this talk, I will introduce some of my group and collaborators' pulsars and FRB research using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). I will talk about the discovery and timing of new pulsars, peculiar pulsar emission geometry, interacting pulsar binary, testing theories of gravitation, as well as results from the FAST FRB key science project, including the large sample repeating FRB studies and what we learned about FRB mechanism from the radio pulsar phase of the magnetar SGR J1935+2154.
Short biography: Weiwei Zhu got his PhD from McGill University (2011). He worked as a post-doc at the University of British Columbia in Canada and then at the Max-Planck Institute for Radio Astronomy in Germany. He joined the National Astronomical Observatories, Chinese Academy of Science (NAOC) as a professor in 2017 and FAST's early science and commissioning team, serving as a key member of FAST's key science projects. He is now the leader of the pulsar and gravitation group in the NAOC. He studies pulsars and Fast Radio Bursts using FAST and the precursors of Square Kilometer Array (SKA). His group also builds radio telescopes and digital backend systems.
