The Extreme Universe: from Supernovae to Pulsars

Speaker Dr. Stephen C.Y. Ng
Affiliation McGill University
Date March 15, 2012 (Thu)
Time 12:30 p.m.
Venue Room 522, 5/F, Chong Yuet Ming Physics Building, HKU

Abstract

Massive stars end their lives as violent supernova explosions --- one of the most energetic events in the universe, and the dense cores left over could form rapidly rotating neutron stars known as pulsars. In this talk, I will describe the rich physical phenomena in the supernova aftermaths, which provide ideal test grounds for extreme astrophysics, from particle acceleration in supernova and pulsar wind shocks to ultra-strong magnetic fields in pulsars. I will highlight recent results from multi-wavelength studies of these objects, including the latest evolution of the remnant of SN 1987A, magnetic field structure of pulsar wind nebulae, and X-ray observations of magnetars and high magnetic field pulsars. Prospects for future studies with upcoming telescopes will also be discussed.

Coffee and tea will be served 20 minutes prior to the seminar.
