The discovery of the first pulsar in a binary star system, the Hulse–Taylor pulsar, 50 years
ago opened up an entirely new field of experimental gravity. For the first time it was possible …

We review the main properties, demographics and applications of binary and millisecond
radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years …

Fast radio bursts (FRBs) are bright, millisecond-duration radio transients originating from
sources at extragalactic distances, the origin of which is unknown. Some FRB sources emit …

Double neutron star (DNS) systems represent extreme physical objects and the endpoint of
an exotic journey of stellar evolution and binary interactions. Large numbers of DNS systems …

The first gravitational wave detections of mergers between black holes and neutron stars
represent a remarkable new regime of high-energy transient astrophysics. The signals …

Context. High-mass X-ray binaries (HMXBs) are a particular class of high-energy sources
that require multi-wavelength observational efforts to be properly characterised. New …

Fast radio bursts (FRBs) are brief, intense flashes of radio waves from unidentified
extragalactic sources. Polarized FRBs originate in highly magnetized environments. We …

Radio pulsars are rapidly rotating highly magnetized neutron stars. This comprehensive
book is a unique resource that brings together the key observational techniques …

After initial claims and a long hiatus, it is now established that several binary stars emit high-
(0.1–100 GeV) and very high-energy (> 100 GeV) gamma rays. A new class has emerged …

We summarize 5 years of continuous monitoring of accretion-powered pulsars with the Burst
and Transient Source Experiment (BATSE) on the Compton Gamma Ray Observatory. Our …
