Simon Swordy

Simon Swordy has been involved in experimental research in cosmic rays and high-energy gamma rays for many years. He is currently working with the VERITAS high-energy gamma-ray telescope in Arizona. In the 1990s he was part of the HEAT balloon collaboration that made an important investigation of positron and antiproton abundances in cosmic rays at energies above 10GeV. He received his Ph.D. from the University of Bristol in 1979 and is at present the Director of the Enrico Fermi Institute at the University of Chicago.

Many cosmologists believe that antiprotons in cosmic rays come from the annihilation of dark matter. Data from the PAMELA experiment on board a Russian satellite provide an important test of this possibility.
