Gold, uranium, and other heavy elements on Earth did not form here. They were born in the violent deaths of massive stars and the collisions of neutron stars, traveling across the galaxy before ...

Andrea Richard receives funding from the Department of Energy, National Nuclear Security Administration.

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these ...

Peter Bender, Assistant Professor, Department of Physics and Applied Physics, University of Massachusetts Lowell will give a talk on “Seeing the Invisible: High-Resolution γ-Ray Spectroscopy of Rare ...

Rosatom has begun preparations for BN-1200M MOX fuel production at Zheleznogorsk, aiming for first delivery in 2033.

Neutron star collisions are known to be factories in which heavy elements are produced. The fusion that takes place inside ...

A companion star may have stripped silicon layers. This provided a new window into stellar death. Astronomers have observed the inner layers of a dying star through a rare type of stellar explosion ...

New simulations show that neutrino flavor transformations change both the composition and the signals left behind after neutron star collisions. When two neutron stars collide and merge, the result is ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic ...

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, ...

Astronomers have witnessed a rare “extremely stripped supernova” that exposed the inner silicon layers of a dying star, confirming theories of stellar fusion and offering new insight into how ...
