Pulsars are rapidly rotating neutron stars, the extremely dense cores left behind when massive stars explode. Astrophysicists have recently observed a pulsar rotating over 300 time...
Pulsar Timing Arrays have been used to observe the background of gravitational waves in our galaxy. We aren't certain of their origin, but a new study shows a strong source could b...
Astronomers have detected extreme, never-before-seen behavior from a rare kind of pulsar and stumbled on a surprising link to one of astronomy's biggest current mysteries. Using 17...
A new study suggests that pulsar timing arrays could help reveal how the Universe’s first supermassive black holes formed. A faint background of extremely low-frequency gravitation...
Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars...
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that...
Using data from the Japan-led XRISM observatory, astronomers have directly observed a giant star’s stellar wind captured by its compact companion (triggering X-ray flares) for the...
Einstein Probe and LHAASO observations reveal a 42-light-year X-ray tail, showing high-energy particles can travel directionally far beyond their pulsar source.
A pair of white dwarfs race around each other every 374 seconds, creating a rhythmic X-ray beacon that could reveal powerful gravitational waves. Every 6.2 minutes, two dead stars...
«Роскосмос» продемонстрировал визуализацию объектов, за которыми наблюдал работающий в жёстком рентгеновском диапазоне российский телескоп ART-XC. В космическом агентстве рассказал...
Understanding the origin, acceleration and propagation of high-energy cosmic rays has been a century-old mystery in astrophysics. Recently, joint observations from China's Einstein...
For decades, astronomers have identified collisions between two neutron stars through bursts of gamma rays that can disappear in less than two seconds. But some of these violent en...
Learn more about magnetars and how they may also form from two colliding neutron stars.
New observations helped connect an X-ray flash lasting nearly ten minutes to a merger of neutron stars.
A group of astronomers proposes that a series of events in a distant galaxy formed both a black hole and a pulsar, but other experts say the conclusion is premature
All neutron stars have intense magnetic fields. The typical magnetic field of a neutron star is about 100,000 times stronger than the strongest magnetic fields we can create on Ear...
Einstein Probe uncovered a hidden soft X-ray phase that may reveal how neutron star merger remnants remain active after short gamma-ray bursts. A burst of gamma rays can flare for...
X-rays showcase some of the most unique astronomical objects in the universe. Neutron stars and black holes siphoning gas from companion stars stick out like sore thumbs at this le...
Using data from the Japan–led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star's outflow, called a stellar wind, being ca...
Supermassive black holes generate tremendous amounts of energy through their accretion disks and jets. But they can also generate energy through the magnetic Penrose process. A new...
Magnetars are neutron stars with magnetic fields a thousand times stronger than normal. One way that magnetars might form is through the merger of two small neutron stars.
Galactic black holes are cosmic mitochondria, powerhouses of the universe. Most of the energy these supermassive black holes produce comes from the material surrounding them: super...
Astrophysicists at Syracuse University in New York think they've found a hitherto-hidden explanation for strange activity during so-called repeating partial Tidal Disruption Events...
Astronomers have identified a peculiar radio transient in the Milky Way that has remained active for more than two decades, defying the behavior expected of known classes of galact...
