X-rays: burstsGamma-ray bursts (GRBs) can be divided into three groups: short-, intermediate- and long-duration bursts. While the progenitors of the short and long ones are relatively known, the progenitors of the intermediate-duration bursts (IBs) are generally unknown. However, recent ...
Isolation of X-rays and gamma rays by a common alternative wavelength (or equivalent frequency or photon energy). Below any wavelength is defined as noncombustion, such as 10−11 m (0.1 A), called a gamma ray. This parameter allocates photons in an ambiguous range, but it is possible ...
The meaning of GAMMA RAY is a photon emitted spontaneously by a radioactive substance; also : a photon of higher energy than that of an X-ray.
Cadmium zinc telluride CZT is a room temperature semiconductor that directly converts X-ray or gamma-ray photons into electrons. Kromek specialises in growing CZT crystals and turning it into radiation detectors that offer excellent energy resolution and
Since the rate of these candidate afterglow events, 0.15 /day, isconsistent with the BATSE logN-logS distribution, no difference in prompt vs.afterglow beaming is required. However more sensitive x-ray monitors or hardx-ray imaging surveys, with better temporal and spatial resolution, couldprovide...

Gamma-ray telescope, instrument designed to detect and resolve gamma rays from sources outside Earth’s atmosphere. Gamma rays are the shortest waves (about 0.1 angstrom or less) and therefore have the highest energy in the electromagnetic spectrum. Sinc
