La collaboration ATLAS annonce avoir observé pour la première fois la production d un triplet de bosons W, à savoir la création simultanée de trois bosons W massifs au sein.
Researchers at CERN are beginning to generate very high energy neutrinos and capture their behavior when they interact. This will help astronomers studying exotic astronomical phenomena.
Star Swallowed by Supermassive Black Hole Sends Ghostly Particle to Earth
A high-energy particle, thought to have been sent our way by a supermassive black hole hundreds of millions of years ago, has collided with Earth and offered astronomers a rare insight into black holes.
Supermassive black holes are behemoths hiding in the centers of galaxies. Their gravitational force is so strong that if an unlucky star gets too close to it, the star will be shredded into pieces.
Astronomers call this a tidal disruption event. The black hole then swallows the remains of the star, temporarily giving off light, as the black hole is full of energy.

In a distant galaxy, a supermassive black hole ripped a star to bits, sending out an enormous blast of energy. For the first time, researchers have observed a neutrino that probably came from this type of cataclysm, which is called a tidal disruption event or TDE.
Neutrinos are tiny particles that rarely interact with other matter, making them extremely difficult to detect. On 1 October 2019, the IceCube Neutrino Observatory in Antarctica spotted a neutrino with relatively high energy that appeared to come from beyond our galaxy.

Meanwhile, Robert Stein at the German Electron Synchrotron (DESY) and his colleagues were using the Zwicky Transient Facility in California to watch a star that had got too close to a supermassive black hole. The extreme gravity of the black hole shredded the star, creating a TDE that lasted for months. The TDE and the IceCube neutrino came from the same location in the sky, indicating that the ripped-up sta
