Researchers investigate pulsations of the ultra-luminous X-ray pulsar M82 X-2

Using NASA's Chandra spacecraft and ESA's XMM-Newton satellite, Chinese astronomers have inspected the pulsations of an ultra-luminous X-ray pulsar known as M82 X-2. Results of the study indicate that the pulsar showcases a long-term spin-down trend. The study was detailed in a paper published December 28 on the pre-print server arXiv.
