When a massive star dies, astronomers expect a familiar chemical script: hydrogen and helium on the outside, heavier elements ...
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 ...
Imagine watching a massive star that's been burning steadily for millions of years suddenly dim, fluctuate, and then vanish ...
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 ...
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013.
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 ...
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 ...
