Neutrinos of different “flavor” quantum states (shown by colors) are entangled through interactions. In dense neutrino environments like core-collapse supernovae, this leads neutrinos of different ...

When massive stars reach the end of their lives, something strange and violent happens deep inside them. As they run out of fuel, their cores begin to collapse under their own weight. But this ...

When a massive star dies, astronomers expect a familiar chemical script: hydrogen and helium on the outside, heavier elements ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

PASADENA, Calif.–Each century, about two massive stars in our own galaxy explode, producing magnificent supernovae. These stellar explosions send fundamental, uncharged particles called neutrinos ...

A neutrino moves through a gas of neutrons and is sensitive to correlations in spin and density in the neutron matter. These correlations determine how much energy transfers from the neutrino to the ...
