Thus, effects due to scattered photons should at best be eliminated or at least be reduced [6]. All kinds of sub-atomic particles existed together, forming a gas of matter, anti-matter and radiation interacting in the same way as they do in present high-energy accelerators or violent cosmic phenomena like quasars or super-novae. Some physics theories suggest that dark matter is made of WIMPS (weakly interacting massive particles), a class of particles that are their own antimatter partner particles. Image formation is based on the mathematical concept of compounded conical projection. Principles Of Radiation Interaction In Matter And Detection. It's responsible for a galactic glow, an abundance of anti-matter, and now — three quiet little taps in an underground mine. However, due to the interaction of radiation with matter, gamma-ray imaging is plagued by Compton scatter, which degrades image quality and spatial resolution. Ultraviolet (UV)-visible spectrometers are used to analyze the interactions between radiation and matter in the UV-visible region of the electromagnetic spectrum. When matter and According to MIT's Samuel Ting, a physicist and the Alpha Magnetic Spectrometer's principle investigator, the first results will be published in two weeks, and “it won't be a minor discovery”; the paper has so far passed 30 revisions and is finally set for publishing. Presumably a similar principle applies to weakly-interacting dark matter particles. Begin to interact with each other and self-annihilate, producing a characteristic positron energy signature that the Alpha Magnetic Spectrometer 2, aboard the International Space Station, may have recently detected (see this AmericaSpace article). It entails a Radon transform defined on circular cone surfaces in order to express the scattered radiation flux density on a detecting pixel. Essentially, the interactions and collisions within the accretion disk convert the momentum energy of the orbiting matter into radiation.
