Gravity waves from black holes

More than a thousand million years before dinosaurs roamed Earth, a ripple in space was spreading through the universe. Traveling at 300,000 kilometers per second, the speed of light, it had covered 95 percent of its journey to Earth when the dinosaurs became extinct. By Mike Albrow.

Search for sterile neutrinos in MINOS and MINOS+

The MINOS+ collaboration at the Department of Energy’s Fermilab has published a paper in Physical Review Letters about their latest results: new constraints on the existence of sterile neutrinos. The collaboration has exploited new high-statistics data and a new analysis regime to set more stringent boundaries on the possibility of sterile neutrinos mixing with muon neutrinos. They have significantly […]
