WebApr 9, 2024 · NGC 4151, a nearby Seyfert galaxy, has recently been reported to emit gamma rays in the GeV range, posing an intriguing astrophysical mystery. The star formation rate of NGC 4151 is too low to explain the observed GeV flux, but the galaxy is known for its coronal activity in X-ray and jet activity in radio. We propose that either the … WebGamma rays are high-energy photons (about 10 000 times as much energy as the visible photons), the same photons as the photons forming the visible range of the electromagnetic spectrum – light.

WebBetter ways for detection of beta and gamma rays with greater energy resolution than that currently available would have great advantages for nuclear physics experiments. Low … WebExcept for low-energy photons, it is quite possible for an incident gamma-ray photon to pass completely through the detector without interacting. In such cases, the total efficiency will then be substantially less than 100 percent. Furthermore, many of the gamma-rays may deposit only a fraction of their energy in the detector.
