A group led by scientists from the RIKEN Cluster for Pioneering Research, using coordinated observations of the Crab pulsar in a number of frequencies, have discovered that the “giant radio pulses” which it emits include an increase in x-ray emissions in addition to the radio and visible light emissions that had been […]

Kornmesser Quasar also can serve as ‘beacon’ for studying closer objects. Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and Very Long Baseline […]

This illustration shows the NANOGrav project observing cosmic objects called pulsars in an effort detect gravitational waves – ripples in the fabric of space. The project is seeking a low-level gravitational wave background signal that is thought to be present throughout the universe. Credit: NANOGrav/T. Klein An international team of […]

Super Heavyweight and Flyweight in a Cosmic Dance Volunteer distributed computing project Einstein@Home discovers neutron star in unusual binary system. After more than two decades, an international research team led by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) in Hannover has identified a Galactic “mystery source” of gamma rays: a […]
