Researchers have found that ancient stars could generate elements heavier than those naturally found on Earth, with atomic masses over 260. This discovery enhances our…
Scientists have used supercomputer simulations to study gravitational waves produced by merging neutron stars, revealing a correlation between the remnant temperature and wave frequency. These…
Scientists have made a significant breakthrough in understanding neutron star glitches through experiments with ultracold supersolids. This research, linking quantum mechanics and astrophysics, reveals new…
New research using computer simulations and astronomical data has uncovered that some long-lasting gamma-ray bursts (GRBs) are caused by cosmic mergers forming black holes, challenging…
Astronomers using NASA’s JWST and other telescopes have detected a bright gamma-ray burst from a neutron star collision, leading to the first direct observation of…
Artist’s impression of two neutron stars colliding, known as a “kilonova” event. Credit: Elizabeth Wheatley (STScI) Astrophysicists propose observing colliding neutron stars (kilonovae) as a…
The Niels Bohr Institute proposes using kilonovae (explosions from merging neutron stars) to address discrepancies in measuring the Universe’s expansion rate. Initial results are promising,…
MIT astronomers mapped the “disk winds” associated with the accretion disk around Hercules X-1, a system in which a neutron star is drawing material away…

Researchers have successfully synthesized an exotic, but very short-lived, Lambda resonance known as Λ(1405) for the first time. Scientists at Osaka University were part of…
Numerical simulation of the neutron stars merging to form a black hole, with their accretion disks interacting to produce electromagnetic waves. Credit: L. Rezolla (AEI)…
This artist’s impression shows a kilonova produced by two colliding neutron stars. While studying the aftermath of a long gamma-ray burst (GRB), two independent teams…
Merging neutron stars, illustrated here, produce a blast of gamma rays when they come together and collapse into a black hole. Observations of two bursts…
