Pulsars

Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars.

It was while she was a graduate student at Cambridge, working under the direction of Antony Hewish, that Jocelyn Bell discovered pulsars.

In 1974, the Nobel Prize in physics was jointly awarded to astronomers Antony Hewish and Sir Martin Ryle. Antony Hewish was honored for the discovery of pulsars. Many have argued that Jocelyn Bell Burnell should have shared that honor.

Pulsars are dense remnants of dead stars that regularly emit beams of radio waves, which is why some call them "cosmic lighthouses."

Because their rapid pulse of radio emission is so predictable, a large array of well-understood pulsars can be used to measure extremely subtle abnormalities, such as gravitational waves.

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is one of the leading groups of researchers using pulsars to search for gravitational waves.

Pulsars, which are one class of neutron star, spin up to hundreds of times each second and sweep beams of energy toward us with every rotation.

For decades, scientists have been trying to figure out exactly how pulsars work.

I read the article "On the search for artificial Dyson-like structures around pulsars."

Pulsars are compact and rapidly rotating neutron stars which are the remains of stars that have exploded.
