It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

There's lots to discover in the electromagnetic spectrum. Here's a tour that ... ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed ...

For convenience the energy scale of a Mössbauer spectrum is thus quoted in terms of the source velocity, as shown in Fig1. With an oscillating source we can now modulate the energy of the gamma-ray in ...

They belong to a larger group of active galaxies that host active galactic nuclei (AGN), and are the most numerous extragalactic gamma-ray sources ... flat-spectrum radio quasars (FSRQs) that ...
