By measuring both the positions of stars and the times when pulsar pulses reach us, we might identify gravitational waves emitted by exotic processes right after the Big Bang.
Most pulsars gradually spin slower and slower, making weaker and weaker radio pulses until the pulses stop altogether. Today’s paper is about a star that has spun its neutron star companion back up, recycling it into a millisecond pulsar.
Whether you like them or not, magnetic fields permeate the interstellar medium. Today’s paper outlines a novel way of observing them!
Guest author Giovanni Cozzolongo tells us about peculiar pulsar magnetic fields!
MeerKAT, a radio telescope, made a movie of the 2020 Great Conjunction between Jupiter and Saturn, and found a new pulsar in the background.
