Michael Cherry received his Ph.D. from the University of Chicago in 1978. He then worked with the gamma-ray astronomy group at the University of New Hampshire and the particle astrophysics group at the University of Pennsylvania. In 1988, he moved to Louisiana State University, where he is a member of the high-energy astrophysics group and chair of the Department of Physics and Astronomy. His research has involved measurements of high-energy cosmic rays, neutrinos, and gamma rays.


An abrupt slowdown for particles on the fast track

Forty years ago, it was predicted that there would be a sharp cutoff in the intensity of the very-high-energy cosmic rays that strike the earth’s surface. Two collaborations—the HiRes and Auger telescopes—are providing compelling evidence for this so-called “GZK effect.” Read More »
