Neutron stars and pulsars
Sufficiently massive stars of about 8 solar masses or more end their lives in supernova explosions, mainly by core collapse. The resulting compact objects are called neutron stars and were first discovered in 1967. These dead stars are extreme objects in many ways and so act as laboratories for us to study physics under extreme conditions, much beyond what is possible on Earth.
The gasenous remains that are expelled at high velocities during a supernova explosion are known as supernova remnants.
I have been part of the recommissioning team at the Molonglo Synthesis Radio Telescope near Canberra, Australia and I am currently involved with commissioning the MeerTRAP realtime detection system for the MeerKAT telescope array in South Africa. My work includes the design and implementation of reliable communication and control systems for these telescopes and the design of efficient telescope scheduling algorithms.
