Aug 10, 2016 · Unlike optical light and x-rays, gamma rays cannot be captured and reflected by mirrors. Gamma-ray wavelengths are so short that they can pass through the space within the atoms of a detector. Gamma-ray detectors typically contain densely packed crystal blocks. As gamma rays pass through, they collide with electrons in the crystal.
Gamma rays provide information about some of the most energetic phenomena in the universe; however, they are largely absorbed by the Earth's atmosphere. Instruments aboard high-altitude balloons and satellites missions, such as the Fermi Gamma-ray Space Telescope, provide our only view of the universe in gamma rays.
Nov 18, 2014 · A magnetic field exerts a force on a charged particle that is moving in it. This causes the particle to radiate, with the emitted power being proportional to the square of the force divided by the square of the mass of the particle. For electrons, this radiation is often in the gamma-ray region of the electromagnetic spectrum. The character of ...
Apr 13, 2017 · The majority is in the form of visible, infrared, and ultraviolet radiation (UV). Occasionally, giant explosions, called solar flares, occur on the surface of the Sun and release massive amounts of energy out into space in the form of x-rays, gamma rays, and streams of protons and electrons. This is called a solar particle event (SPE).
Jun 1, 2023 · Its GBM (Gamma-ray Burst Monitor) and Large Area Telescope allow the detection and follow-up of bursts from X-rays to the highest-energy gamma rays detected in space – an energy span of 100 million times. This has enabled the discovery of afterglow gamma rays with billions of times the energy of visible light. The Next Revolution
Apr 22, 2023 · The researchers envision that a fleet of such cubesats would make it possible to find sources of gamma-ray bursts across the entire sky through the so-called triangulation, the same method used to ...
