Astrophysicists using a telescope embedded in Antarctic ice have succeeded in a quest to detect and record the mysterious phenomena known as cosmic neutrinos – nearly massless particles that stream to Earth at the speed of light from outside our solar system, striking the surface in a burst of energy that can be as powerful as a baseball pitcher’s fastball. Next they hope to build on the early success of the IceCube Neutrino Observatory to detect the source of these high-energy particles, said Physics Professor Gregory Sullivan, who led the University of Maryland’s 12-person team of contributors to the IceCube Collaboration.
Ana Maria Rey, a former UMD graduate student, who did her thesis work with Charles Clark, was named a 2013 MacArthur Foundation Fellow. Rey, a native of Colombia, is currently a JILA fellow and University of Colorado professor. Her research group focuses on ultracold atoms, optical lattices and the underlying physics of these systems, which has applications in condensed matter and quantum information science. JILA is a research partnership between CU and NIST, Boulder.
World’s Most Sensitive Dark Matter Detector

After its first run of more than three months, operating a mile underground in the Black Hills of South Dakota, a new experiment named LUX has proven itself the most sensitive dark matter detector in the world.
“This result shows that LUX is working quite well”, says Carter Hall, associate professor of physics at the University of Maryland and leader of the Maryland LUX group. “With just a fraction of our final dataset in hand, we’ve produced an important science result, and we’ve demonstrated the promise of the full dataset which we’ll be collecting in the coming years.”
