The Terahertz region of the electromagnetic spectrum, which spans from 100 GHz to 10 THz, has attracted a lot of attention in recent years due to the developments in new generation and detection techniques and due to the potential applications in the commercial, scientific, and government areas. THz Principles: THz principles and interaction with matter. Baryonic matter can, in principle, be detected through the electromagnetic radiation it releases. It is due to these properties that they cannot be easily detected. But there's a problem: the amounts of baryonic matter detected via Much of this tenuous, filamentary gas remains undetected, but astronomers expect that it could most likely be found between interacting galaxy clusters, where the filaments are compressed and heated up, making them easier to spot. Presumably a similar principle applies to weakly-interacting dark matter particles. THz Fundamentals: Electromagnetic radiation and propagation fundamentals. 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). Essentially, the interactions and collisions within the accretion disk convert the momentum energy of the orbiting matter into radiation. Neutrinos have nearly no mass, no charge and interact negligibly with ordinary matter.
