Scientists have created a perovskite-based gamma-ray detector that surpasses traditional nuclear medicine imaging technology. The device delivers sharper, faster, and safer scans at a fraction of the ...

Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA’s orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat ...

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

High energy scans or the body looking for tumors or infections could be greatly improved by adopting perovskite detectors instead of the fragile or low-resolution options currently in use, a new study ...

A photon’s transit from the center of the sun outward into space takes tens of thousands of years, but it requires only a few minutes to reach Earth once it emerges. An airplane is juxtaposed with the ...

The HESS international collaboration, to which CNRS and CEA contribute, has published the results of fifteen years of gamma ray observations of the Milky Way. Its telescopes installed in Namibia have ...

The Crab nebula is blasting high-energy gamma rays at us. Researchers using the Large High Altitude Air Shower Observatory (LHAASO) in China have found the second highest-energy gamma ray, or photon, ...
