Lei Zhang Colloquium: Pulsar Observation and Study with FAST and the Parkes Radio Telescope

Remotely hosted

Abstract

Pulsars are dense objects. They emit beams of radiation that are often detected using radio telescopes. Not only are they rich in radiation phenomena, natural laboratories for studying the nature and physical laws of materials under extreme conditions, but also probes for studying interstellar medium as well as gravitational waves and their generation processes. In this talk, we will present one FAST new discovery pulsar J1926-0652, which is a pulsar with a plethora of single pulse behavior previously unseen for most such pulsars and these complexities pose challenges for the classic carousel-type models of single-pulse emission. We will also present the first wide-band observations of three MSPs in 47 Tucanae using the Ultra-Wideband Low (UWL) receiver at Parkes. Both of these two works not only enable us to optimize the way to find more unknown pulsars, but also to help us to better understand pulsars themselves.
