Using archival data from ESA’s XMM-Newton spacecraft and NASA’s Chandra X-ray observatory, astronomers have investigated one of gamma-ray radio-quiet pulsars known as PSR J1826−1256. The study, based on X-ray observations, sheds more light into the nature of this peculiar object and its pulsar wind nebula (PWN). Results of the research were presented in a paper published June 3 on arXiv.org.
