Gamma rays would be the universe’s most energetic variety of sunshine. They go straight by optics used for other wavelengths, producing them unattainable to reflect or refract. As an alternative, astrophysicists use Specific detectors to observe gamma rays and to determine where they originate from from the sky.
X-ray mirrors use the slightly angled aspect of your paraboloid. X-rays can just go through the atoms which make up most telescope mirrors. To detect them, engineers turn the mirrors on their sides And so the X-rays can skip off the surface. This known as a grazing incidence mirror.

) A number of levels of higher-precision silicon detectors monitor the particles because they shift with the instrument. The course from the incoming gamma ray is determined by projecting the particle paths backward. The particles journey in the trackers until finally they access a different detector referred to as a calorimeter, which absorbs them and actions their energies.
