Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars. These mergers are known to generate gravitational waves, energy-carrying ...

The transformation of neutrinos in a neutron star merger could be crucial to shaping the way events of the collision unfold. For the first time, a team of physicists has simulated how neutrinos change ...

Physicists provide a viable and testable explanation for how UHECRs are created. Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million ...

New research suggests that colliding neutron stars can briefly "trap" ghostly particles called neutrinos, which could reveal new secrets about some of space's most extreme events. When it comes to ...

A brilliant flash from deep space once baffled scientists. But now, that mystery has been solved—and it reshapes what we know about the universe’s heaviest elements. Back in December 2004, a massive ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
