interactions of cosmic rays with matter, and matter–antimatter annihilation; it is found, "...that a matter–antimatter symmetric universe is empirically excluded..." Nuclear lines, i.e. solar gamma rays, or lines from radioactive decay (nucleosynthesis), like the 1.809MeV line of radioactive...
gamma rays, burstsIndividual gamma-ray bursts (GRBs) have very diverse time behavior---from a single pulse to a long complex sequence of chaotic pulses of different timescales. I studied time profiles of GRBs using data from the Compton Gamma Ray Observatory's Burst and Transient Source ...
~6 Li AND GAMMA RAYS: COMPLEMENTARY CONSTRAINTS ON COSMIC-RAY HISTORYThe rare isotope ~6Li is made only by cosmic rays, predominantly in αα→ ~6 Li fusion reactions with interstellar medium (ISM) helium. Consequently, this nuclide provides a unique diagnostic of the history of cosmic rays ...
Radium is an element that emits huge quantities of alpha particles and gamma rays; which, like x-rays, “Had the power to cure any ailment”. As such, it was added to everything from wristbands to drinking water and was bought by the publicen masse. Circa 1917, thousands of women were...
A historical account of the discovery of the electromagnetic spectrum and its uses in Astronomy. Radio waves, infra-red, visible light, ultra violet, X-rays and gamma rays are explained. An account of how various properties of stars can be measured by studying starlight. Includes brightness, ...

The luminosity of a spiral galaxy is related to the properties of a particular radio emission in its spectrum. The apparent light smoothness of elliptical galaxies is related to their distance. Distant galaxies that give off X-rays affect the Universal Background Radiation lying between them and ...

Heat or infrared radiation, is part of the electromagnetic spectrum, which also includes visible light, radio waves, ultraviolet light, gamma rays and x-rays. Hyperstorm can project any of these. He can maintain total control of an entire planets electromagnetic field and can manipulate it ...
