Scientists link star-shredding event to origins of universe s highest-energy particles

Scientists Capture The First Picture Of A Black Hole A group of scientists has detected the presence of a high-energy neutrino a particularly elusive particle in the wake of a star s destruction as it is consumed by a black hole. Neutrinos as well as the process of their creation are hard to detect, making their discovery, along with that of Ultrahigh Energy Cosmic Rays (UHECRs), noteworthy. This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays the highest energy particles in the Universe. The work, which included researchers from more than two dozen institutions, including New York University and Germany s DESY research center, focused on neutrinos subatomic particles that are produced on Earth only in powerful accelerators.

Hebrew U Researchers Observe First Evidence of Delayed Radio Flares from Tidal Disruption Event by a Black Hole | The Jewish Press - JewishPress com | Jewish Press News Desk | 11 Adar 5781 – February 23, 2021

Binary Black Hole (Illustration) A team of researchers from the Hebrew University of Jerusalem led by Dr. Assaf Horesh has discovered the first evidence of radio flares emitted only long after a star is destroyed by a black hole. Published in the periodical Nature Astronomy ( Delayed radio flares from a tidal disruption event), the discovery relied upon ultra-powerful radio telescopes to study these catastrophic cosmic events in distant galaxies called Tidal Disruption Events (TDE). While researchers had known that these events cause the release of radio flares, this latest discovery saw those flares being emitted months or even years after the stellar disruption.
