The Standard Model of particle physics is the best explanation to date for how the universe works at the subnuclear level and has helped explain, correctly, the elementary particles and forces between them. But the model is incomplete, requiring “extensions” to address its shortfalls. Owen Long, a professor of physics and astronomy at the University...
Materials that have excess electrons are typically conductors. However, moiré patterns — interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern — can suppress electrical conductivity, a study led by physicists at the University of California, Riverside, has found. In the lab, the researchers...
A team led by astronomers at the University of California, Riverside, has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the past. Galaxies that appear to have little to no dark matter — nonluminous material thought to constitute 85% of...
The Texascale Days event in December 2020 provided an opportunity for nine research groups to use large sections of the National Science Foundation-funded Frontera supercomputer at the Texas Advanced Computing Center (TACC) to solve problems that in many cases have never been attempted. Simeon Bird, professor of physics and astronomy at the University of California...
