Using four radio telescopes, astronomers from the National Astronomical Observatory of Japan and elsewhere have conducted multi-frequency multi-epoch radio observations of a radio-loud magnetar known as XTE J1810-197. Results ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered a new pulsar in the globular cluster NGC 6712. The newly found object is a so-called "black widow," and the first radio pulsar ...
Using data from NASA's Kepler telescope, Russian astronomers have investigated an X-ray binary known as Scorpius X-1 (or Sco X-1 for short). Results of the study, published September 2 on the arXiv pre-print repository, provide ...
