Overview
Advanced view of Pulsars & Millisecond Pulsars
Pulsars are rotating neutron stars whose beams of electromagnetic radiation sweep across Earth like lighthouse beams, producing extraordinarily regular pulses. Millisecond pulsars rotate hundreds of times per second and are usually old neutron stars spun up by accretion from binary companions.
Pulsar timing tests general relativity, detects binary companions, measures interstellar plasma, constrains neutron-star interiors, and enables pulsar-timing arrays to search for nanohertz gravitational waves.
