    Radio pulses from cosmic rays

    by  • October 28, 2010 • News

    Ultrahigh-energy cosmic rays (UHECRs), with energies exceeding 10^19eV, are rare. A random square kilometer on Earth is hit by a few dozen per century. But their trajectories, relatively undeflected by intergalactic magnetic fields, might reveal their enigmatic sources. So astrophysicists build enormous ground-detector arrays. But even the flagship 3000-km^2 Pierre Auger Observatory in Argentina,...

    Focus: Nuclei Cooperate to Produce Single Particle

    by  • August 7, 2009 • News

    Ultrahigh energy photons striking matter can transform into rho mesons through an interaction that involves many nuclei simultaneously, a phenomenon that may affect the detection signatures of high-energy particles from space. When an energetic photon smashes into matter, it can create a massive particle, the rho meson, when it strikes an atomic nucleus. A...

    Scientists seeking neutrinos: A balloon scours Antarctica for particles that could help unlock the universe’s origins

    by  • February 1, 2007 • News

    The Honolulu Star Bulletin A SCIENTIFIC balloon designed to make the first-ever measurements of high-energy neutrinos has completed a 35-day flight over Antarctica, said University of Hawaii professor Peter Gorham, who is leading the project. As the high-altitude balloon cruised at 120,000 feet above the Antarctic continent, 40 antennas listened for bursts of radio...

    SLAC Creates Mini-Antarctica to Calibrate NASA Antenna

    by  • June 20, 2006 • News

    SLAC Today During the first week of summer in the Northern Hemisphere, SLAC will be home to a mini-Antarctica. Scientists are using a ten-ton block of ice in End Station A to calibrate the Antarctic Impulsive Transient Antenna (ANITA), a radio antenna array that will fly over the South Pole on a NASA balloon...

    The Ghost Particle – Awesome Detectors

    by  • January 8, 2006 • News

    PBS NOVA Scientists estimate that many hundreds of billions of neutrinos will have harmlessly sped through your body by the time you finish reading this sentence. But despite their abundance, there’s only a 10 percent chance over the course of your entire lifetime that even one of these invisible particles will ever (again, harmlessly)...

    High Energy Neutrinos from the Cosmos

    by  • March 23, 2005 • News

    Nobelprize.org Mankind has studied the universe for thousands of years by looking at the fascinating night sky, guided by the visible light emitted from myriads of stars and other phenomena. During the last century new pictures of the night sky have been discovered by scientists using different wavelengths of light which the naked eye...

    Telescope takes test ride

    by  • December 21, 2003 • News

    The Antarctic Sun Inside TRACER mission control, Patrick “JoJo” Boyle sits in the six-foot square office listening to music and watching computer monitors for incoming data and messages. Every now and then Boyle points to the monitor where a string of bright red pixels suddenly appear, indicating a recent high-energy cosmic ray event. The...
