Gamma rays are the highest energy photons (shortest wavelength, highest frequency), arising out of nuclear events during radioactive decay. For in vivo applications, the best gamma rays are of low energy (100–511 keV) because they can penetrate tissues. Gamma rays in this energy range can al...

Invisible to our eyes, gamma rays fall on an extreme end of the electromagnetic spectrum. They have the shortest wavelengths and the highest frequency of any form of light. Visionaries have been trying to push laser technology into the farthest reaches of the electromagnetic spectrum since the inv...
Panel (A): X-ray (XRT, blue closed squares) and VHE gamma rays (the H.E.S.S., red circles) energy flux light curves. Upper limits on MeV 𝛾γ-rays by LAT are also shown (grey arrows). The dashed blue line is the PL fit to the XRT temporal decay obtained by considering only...
Gamma rays, X-rays, visible light, and UV are all of electromagnetic (EM) radiation. EM radiation differs in frequency and hence in energy. Gamma rays are the most energetic form of such electromagnetic radiation, having the energy level from around 10 keV to several hundred kiloelectron volts...
When the jets are observed at angles of less than a few degrees to the line-of-sight, they are called blazars, showing variable non-thermal emission across the electromagnetic spectrum from radio waves to gamma rays. It is commonly believed that shock waves are responsible for this dissipation...
Gamma photons have extremely high frequency and energy, and thus have a high penetrating ability through matter. These photons (especially those which carry high energy) can easily penetrate human tissues and organs, and thus they are considered very dangerous for both humans and the environment. ...

We report the detection of very high-energy gamma-ray emission from the intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS. The source was observed between January and April 2008. A strong outburst of gamma-ray emission was measured in the middle of March, lasting...
Gamma-rays are the highest-energy photons in the ELECTROMAGNETIC SPECTRUM and their detection presents unique challenges. On one hand it is easy to detect γ-rays. The interaction cross-sections are large and above a few MeV the pair production interaction, the dominant γ-ray interaction with ...
