Topic: pulsars

This lecture introduces neutron stars as compact remnants of stellar explosions. It examines the balance against gravitational collapse, their extreme densities and the observational role of pulsars. The Crab pulsar provides a concrete example, while the possible composition of matter deep inside these objects motivates further research.

Fast radio bursts display diverse behaviours, including repetition, and their origins remain under investigation. This seminar considers evidence connecting some bursts to pulsars and strongly magnetized neutron stars, particularly magnetars, while reviewing the range of proposed explanations.

New radio facilities are expanding observations ahead of the Square Kilometre Array. This seminar introduces LOFAR and NenuFAR installations at Nançay, their metre and decametre observing bands, and applications to pulsars, planets such as Jupiter, and possible signals from cosmic reionization.
