Gamma rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers.
Winter. Are gamma-ray bursts the sources of ultra-high energy cosmic rays? Astroparticle Physics, 62:66-91, March 2015.P. Baerwald, M. Bustamante, W. Winter, Are gamma-ray bursts the sources of ultra-high energy cosmic rays? Astropart. Phys. 62 (2015) 66-91. arXiv:1401. 1820, doi...
How are gamma rays detected? What's the difference between x-rays and gamma rays Are gamma rays alpha radiation? How do gamma rays interact with matter? Why are gamma rays dangerous? Are gamma rays light? What is the wavelength of gamma rays?
Alpha, beta, gamma rays: It almost sounds like the tagline of an old-school motion picture about aliens from outer space, newly arrived on Earth with their ultra-high-tech gadgets (and hopefully a warm disposition). In reality, this isn't too far off. Alpha, beta and gamma radiation ar...
Gamma Rays:The electromagnetic spectrum contains different types of energy waves. The strongest of these energy waves are gamma rays, these rays are very strong rays of energy that can be damaging and helpful.Answer and Explanation: Gamma rays are ionizing rays of energy, meaning that gamma rays...
to the poles of the new black hole, where it is blasted out as two polar jets moving at near light speed. These jets emit X-rays and gamma-rays as they barrel through surrounding stellar matter, and these initial high-energy emissions are followed byafterglowsacross theelectromagnetic spectrum...
Why do gamma rays have the greatest penetrating energy? The great penetrating power of gamma rays stems from thefact that they have no electric charge and thus do not interact with matter as strongly as do charged particles. How is gamma radiation used in industry?
Gamma-ray bursts are a real threat to life27 January 2015 Artist’s rendering of a GRB, where life-damaging gamma rays are produced by two relativistic jets powered by a new-born black hole at the heart of an exploding massive star. Image credit: ESO/A Roquette. A new study confirms ...
but it may have been a quasar just a few million years ago (Figure 4). Two giant bubbles that extend 25,000 light-years above and below the galactic center are emitting gamma rays. Were these produced a few million years ago when a significant amount of matter fell into the black hole...
Gamma rays aren't always a deadly threat: in medicine, they're used to treat cancer (among other things). However, there are cosmic sources of these killer photons, and for the longest time, they remained a mystery to astronomers. They stayed that way until telescopes were built that could...
