Researchers Use Computer Models to Study Dark Matter

A team of researchers is using computer simulations to study the hypothetical particle that physicists call dark matter. Dark matter is a hypothesized form of matter particle that doesn’t reflect or emit electromagnetic radiation. Physicists have guessed at its existence based on their observation of gravitational effects on physical matter, such as stars and galaxies. Researchers from the Paris Institute of Astrophysics, Ohio State University, and the University of Illinois at Urbana-Champaign have created detailed computer simulations exploring the density profiles of possible dark-matter voids in more detail than previous studies. The scientists could use the simulations to compare theory and prior simulations with observational data. The researchers published their findings in the journal Physical Review Letters.
