An article published in “The Astrophyiscal Journal” reports a study of the pulsar PSR J1023+0038, which showed a peculiar behavior given that for the first time both visible light and X-ray emissions were detected. A team of researchers led by Alessandro Papitto of the Italian National Institute of Astrophysics used the Galileo National Telescope in the Canaries and ESA’s XMM-Newton Space Telescope to capture the different emissions of what’s classified as a millisecond pulsar for its very fast rotation speed and offer an explanation to his behavior.
