Astronomers are making significant progress in identifying the origins of the highest energy cosmic rays, with evidence pointing to our own galaxy. Using detectors like IceCube and LHAASO, scientists have traced these particles back to sources such as pulsar wind nebulae, supernova remnants, and black holes within the Milky Way, advancing our understanding of cosmic particle acceleration and multi-messenger astronomy.
Chinese scientists have created a new map of the Milky Way using data from the Large High Altitude Air Shower Observatory (LHAASO), challenging conventional theories about cosmic radiation. The map reveals that the galaxy's disc emits gamma rays at ultra-high energies, contradicting previous models that predicted a cut-off point. The findings suggest that existing models need significant modifications and provide new insights into the origins and propagation of cosmic rays. The research highlights the importance of collaboration among major cosmic ray detectors to confirm observation results and gain a better understanding of cosmic radiation.
Scientists from the Large High Altitude Air Shower Observatory (LHAASO) have published a groundbreaking study on the gamma-ray burst (GRB) GRB 221009A, an astronomical event resulting from the explosion of a massive star two billion years ago. LHAASO observed the complete high-energy light curve that other experiments have yet to reach, providing a perfect data base for precise tests of theoretical models. The study challenges current theoretical models and provides invaluable data for understanding GRB mechanisms.
The Large High Altitude Air Shower Observatory (LHAASO) has recorded the entire process of a tera-electron volt gamma-ray burst (GRB) from the death of a massive star, named GRB 221009A. LHAASO's observations have provided a perfect database for precise tests of theoretical models. The rapid enhancement of photon flux at the beginning of the afterglow exceeds the expectations of previous theoretical models, leading to discussions within the scientific community regarding the mechanisms involved in GRBs. LHAASO's data-intensive observations at high-energy will reveal more mysteries.
The Large High Altitude Air Shower Observatory (LHAASO) captured data from the brightest supernova yet observed, known as the BOAT, providing new information on gamma-ray bursts. The data suggests that lower energy events are caused by the jets interacting with the turbulent debris of the supernova, while higher energy photons are produced in areas where the jets have cleared the supernova debris and are starting to interact with the material that formed the environment around the star. The BOAT was as bright as observed because the central core of its jet was pointed directly at Earth.
