Are all gamma rays shorter than x-rays? What type of radiation does the sun produce? What are alpha, beta and gamma decay? What produces electromagnetic radiation? What is Lyman-alpha radiation? What type of ionizing radiation is emitted by fluoroscopy?
Delve into the world of gamma rays, the electromagnetic emissions from certain radioactive elements. Learn about their distinct nature and call the experts.
Speed of Gamma Rays: Gamma rays are electromagnetic waves and are part of the electromagnetic spectrum. They occupy a position near one extreme of the spectrum and have very short wavelengths (in the picometer or smaller range) and very high frequencies (in the exahertz (EHz) range or higher...
Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy can now be performed in far more detail and extended into the MeV regime, ...
When antimatter and matter collide, the annihilation produces bursts of gamma rays. Dark matter can also produce gamma rays when it and its counterpart, dark antimatter, collide to produce standard matter. And finally, dark matter isn’t just a different class of the three families of ordinary ...
We find that, based on this existing data, we can limit $ au$ lepton, quark, direct gamma-ray, and weak boson channels to levels below the canonical relic cross-section. This allows us to set new limits on the branching ratios of $S$ decay, which can rule out a Higgs-like decay ...
How does your work involve gamma-ray bursts? When a GRB happens, it produces a jet of gamma-rays and other material. When this material interacts with all the other dust and particles around it, it energizes that material, which then produces emission from the X-ray to radio bands, known...
In 2014, NASA'sFermi Gamma-ray Space Telescopemade maps of the heart of our galaxy, theMilky Way, in gamma-ray light, revealing an excess of gamma-ray emissions extending from its core. "The signal we found cannot be explained by currently proposed alternatives and is in close agreement wi...
If you go all the way out on the electromagnetic spectrum, you will see that gamma rays are the most energetic. This should come as no surprise since it is commonly known that gamma rays have enough energy to penetrate many materials. These rays are very dangerous because of the damage ...
Matter—the visible kind, that is—interacts with the universe in many ways. It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating...
