Federal money to allow U.S. and European collaboration to study coherent light sources beyond x-rays. Combining Rochester’s theoretical expertise with ELI Beamlines’ experimental skills. U.S. Federal ...

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

A lead halide material can detect and image single gamma-ray photons with both high-spatial and high-energy resolution ...
