What are gamma rays made up of? Gamma Rays: All the atoms are composed of the nucleus with protons and neutrons as part of the nucleus. The nucleus may sometime get unstable due to some reason and achieve stability after undergoing a radioactive decay. This decay is of three types, alpha...
Delve into the world of gamma rays, the electromagnetic emissions from certain radioactive elements. Learn about their distinct nature and call the experts.
What are gamma rays made up of? What are radio waves used for? How has the excimer laser developed over the years? What is different about the fast excimer gas laser? What is the difference between visible light and x-rays? What is a free electron laser?
Within a year, BATSE was detecting around one GRB per day, and the spacecraft went on to produce the first-ever all-sky survey in gamma-rays. This revealed that GRB sources are distributed almost evenly (or "homogeneously") across the universe, according to the Swinburne Centre for ...
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, ...
Therefore, assuming $S$ decays promptly, it should be possible to check what constraints are imposed upon the effective DM annihilation cross-section in the Madala scenario by hunting signatures of $S$ decay that follows DM annihilation within dense astrophysical structures. In order to make use ...
"Rays" is actually short for the general term electromagnetic radiation (EM radiation), which travels at the speed of light (denoted c, or 3 × 108 m/s) and comes in a variety of combinations of frequency and wavelength values whose products are c. Gamma rays have very short wavelengths ...
What Are Radioisotopes? Radioisotopes, or radionuclides, are unstable forms of elemental matter either man-made or found in nature. They all undergo a spontaneous process of radioactive decay through the emission of alpha and beta particles, gamma rays, and more. All of the elements on the ...
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...
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 matter like hadrons, leptons, or bosons, the latter two of which were formerly ...
