Some of the brightest and most energetic objects in the Universe are the mystery source of high-energy cosmic neutrinos, new research has confirmed. A comprehensive analysis has been convincing enough to link the galaxies that host the fiery cores known as blazars with these mysterious particles. It’s a result that provides a completely unexpected solution to a problem that has kept astrophysicists scratching their heads for years. “The results provide, for the first time, irrefutable observational evidence that the PeVatron blazar sub-sample is a source of extragalactic neutrinos and thus an accelerator of cosmic rays,” said astrophysicist Sara Buson of the Julius Maximilian University of Würzburg in Germany. Neutrinos are the odd little things at the best of times. These subatomic particles are ubiquitous and are among the most abundant in the Universe. However, their mass is almost zero, they are electrically neutral, and they interact very little with anything else in the universe

From a young age, astrophysicist Robin Cook had a deep desire to understand the world around him. “It’s never nice enough to take things at face value … I’ve always wanted to understand how things work,” he said. It was this natural curiosity that led him to pursue a career researching space and the unknown. “It’s not too surprising that I naturally went into astronomy,” he said. “There are so many unanswered questions in astronomy, we actually have pretty limited knowledge of what’s really out there. “And for me, it’s very interesting.” Seeing the galaxy’s ‘beautiful spiral’ Dr Cook is a research associate at the International Center for Radio Astronomy Research (ICRAR), which is run by Curtin University and the University of Western Australia. Founded in 2009, the research center conducts data-intensive astronomy, engineering and science. Dr Cook studies the structure of galaxies.
