known as short gamma-ray bursts (SGRBs). While the gamma rays last mere seconds, the optical light can continue for hours before fading below detection levels (an event called an afterglow). SGRBs are some of the most luminous explosions in the universe with, at most, a dozen detected...
NASA'sFermi Gamma-ray Space Telescopehas been mapping out the high-energy sky since its June 2008 launch. Earlier this year, the Fermi team released its second catalog of sources detected by the instrument's Large Area Telescope (LAT), producing an inventory of 1,873 objects shining in gamm...

Excelitas Omniblocks and X-Ray power supplies are producing X-rays in medical applications for general radiography, digital radiography, tomography, vascular/interventional imaging, image guided radiation therapy, radiation oncology and veterinary medicine. ...
Using two Maunakea Observatories based in Hawaii, astronomers have successfully detected a short gamma-ray burst (SGRB)—the second-most distant and confirmed explosion—to be ever studied, to date. The afterglow of grb181123b, captured by the Gemini North telescope. The afterglow is marked with...
6.2.3.4Gamma ray Gamma rays, also calledgamma radiationor γ-ray, are a penetrating electromagnetic radiation arising from the radioactive decay of atomic nuclei, which is always obtained fromradioisotopes(cobalt-60 or cesium-137) during the application [82]. As with its high energy and strongpe...
