Latest Extragalactic cosmic ray Stories
Physicists from UCLA and Japan have discovered evidence of "natural nuclear accelerators" at work in our Milky Way galaxy, based on an analysis of data from the world's largest cosmic ray detector.
In the paper the authors from the Key Laboratory of Particle Astrophysics, Institute of High Energy Physics, Chinese Academy of Sciences in Beijing proposed a new model trying to explain the knee at cosmic ray spectra.
Experiments by British scientists could reveal the make-up of the universe, the University of Liverpool said Thursday. The examinations will become part of the Advanced Gamma Tracking Array experiment, which seeks to create a so-called fingerprint of the inside of the atomic nucleus to help scientists understand the universe's structure, including humans and stars, the university said in a release. Scientists will analyze particle interactions that produce gamma rays, the university said, and...
A Los Alamos National Laboratory cosmic-ray observatory has seen for the first time two distinct hot spots that appear to be bombarding Earth with an excess of cosmic rays.
Breakthrough astrophysics research may have established the hitherto mysterious source of exceptionally high-energy cosmic ray emissions.
An international science group Tuesday chose Colorado as the site of a $50 million observatory to measure the cosmic rays that continually bombard the Earth.
In the March 25th 2005 issue of Science Magazine, the High Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists, including UK astronomers from the University of Durham, report results of a first sensitive survey of the central part of our galaxy in very high energy (VHE) gamma-rays. Included among the new objects discovered are two 'dark accelerators' - mysterious objects that are emitting energetic particles, yet apparently have no optical or x-ray counterpart.
Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
