Annihilation signals
Signals produced by the process of particle-antiparticle annihilation, serving as a primary method for the indirect detection of dark-matter.
Key Mechanisms
- dark-matter Context: Dark matter is an invisible substance estimated to be six times more abundant than regular matter and is fundamental to the universe’s large-scale structure.
- wimp Annihilation: A hypothesized mechanism where Weakly Interacting Massive Particles (WIMPs) annihilate, releasing energy.
- Gamma Rays as Tracers: The conversion of mass into energy during annihilation frequently produces high-energy photons, making gamma-ray astronomy a critical observational tool.
