Using NuSTAR spacecraft and the VERITAS array of telescopes, an international team of astronomers has investigated a gamma-ray binary known as HESS J0632+057. The study found that a compact object in this system is most likely a pulsar—a highly magnetized, rotating neutron star emitting beams of electromagnetic radiation. The finding is reported in a paper published November 21 on arXiv.
