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.
