ANIMATION “Sterile neutrinos” are theoretically predicted new particles that offer an intriguing possibility in the quest for understanding the dark matter in our universe. Unlike the known “active” neutrinos in the Standard Model (SM) of particle physics, these sterile neutrinos do not interact with normal matter as they move through space, making them very difficult to […]

Heart of darkness: A view of the accretion disc around the supermassive black hole, with jet-like structures flowing away from the disc. The extreme mass of the black hole bends spacetime, allowing the far side of the accretion disc to be seen as an image above and below the black […]

Recently discovered ripples of spacetime called gravitational waves could contain evidence to prove the theory that life survived the Big Bang because of a phase transition that allowed neutrino particles to reshuffle matter and anti-matter, explains a new study by an international team of researchers. How we were saved from a complete annihilation is […]

The electron antineutrino that created the Glashow resonance event traveled quite a distance before reaching IceCube. This graphic shows its journey; the blue dotted line is the antineutrino’s path.

A visualization of the Glashow event recorded by the IceCube detector. Each colored circle shows an IceCube sensor that was triggered by the event; red circles indicate sensors triggered earlier in time, and green-blue circles indicate sensors triggered later. This event was nicknamed “Hydrangea.” Credit: IceCube Collaboration The South Pole […]

At the University of Notre Dame, part of the Oak Ridge Deuterated Spectroscopic Array measured a reaction that causes noise in some neutrino detectors. Credit: Michael Febbraro/ORNL, U.S. Dept. of Energy Led by the Department of Energy’s Oak Ridge National Laboratory, a new study clears up a discrepancy regarding the […]

The Borexino research team has also succeeded in detecting neutrinos from the sun’s second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time.

The Borexino detector, a hyper-sensitive instrument deep underground in Italy, has finally succeeded at the nearly impossible task of detecting CNO neutrinos from our sun’s core. These little-known particles reveal the last missing detail of the fusion cycle powering our sun and other stars, and could answer still-outstanding questions about […]

ANIMATION The effect that nearly massless, subatomic particles called neutrinos have on the formation of galaxies has long been a cosmological mystery—one that physicists have sought to measure since discovering the particles in 1956. But an international research team including the Kavli Institute for the Physics and Mathematics of the […]
