Giant Pulses From a Tiny Star
Wednesday, April 14, 2021 - 3:30pm PDT
Since their detection in 1967, neutron stars have been studied extensively
at radio wavelengths as well as higher energies. Some neutron stars are known to
spin rapidly and reach very large magnetic fields at their surface.
Such fast rotating neutron stars are referred to as pulsars. They have a
co-rotating magnetosphere and generate emission over large parts of the
electromagnetic spectrum through processes that are not yet understood in
Some pulsars are not equally bright in every rotation. Instead they sporadically
produce giant pulses of extremely bright radio emission.
Such pulses can have durations of a few nanoseconds
and intensities at least a thousand times higher than regular pulses.
In this talk I will give an overview of the multi-wavelength studies of radio
giant pulses that I have carried out with various facilities all around the
world with an emphasis on our latest study with the Neutron Star Interior Composition ExploreR (NICER).
