UMD CMNS Physics S1 Color

The Cosmic Ray Physics Group employs satellite and balloon-borne instruments to make direct measurements of energetic particles from space to answer some of the fundamental questions about the cosmos such as (1) Is the Universe symmetric, and if so where is the antimatter? (2) What is the dark matter? (3) How do cosmic rays get their enormous energies? (4) Are supernovae really the sources of cosmic rays? (5) What is the history of cosmic rays in the Galaxy? Most part of the balloon borne instruments are built in-house by students and young scientists, many of them currently working in the on-campus laboratory.
