Phase variation in the X-ray emissions from three pulsars has been examined using the EPIC instrument on XMM-Newton. In a paper published this week in the Astrophysical Journal scientists reveal that analysis of spectra over the pulsar rotation period has enabled them to track hot spots on the surface of the neutron star.
