Simeon Bird, an assistant professor of physics and astronomy at UC Riverside, is a member of a team of astrophysicists that has used machine learning to simulate the universe with high resolution in a thousandth of the time conventional methods would take. The researchers uploaded models of a small region of space at both low...
Using a bit of machine learning magic, astrophysicists can now simulate vast, complex universes in a thousandth of the time it takes with conventional methods. The new approach will help usher in a new era in high-resolution cosmological simulations, its creators report in a study published online May 4 in Proceedings of the National Academy...
A pair of physicists at the University of California, Riverside, are aiming to convert light falling on atomically thin semiconductor materials into electricity, having received more than $582,000 in funding from the U.S. Department of the Army. Nathaniel Gabor and Vivek Aji, both associate professors of physics and astronomy, will focus on how the fundamental...
Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons — research that could lead to faster and more energy-efficient computers. In ferromagnets, electron spins point in the same direction. To make future computer technologies faster and more energy-efficient, spintronics research employs spin dynamics — fluctuations...
Kenneth N. Barish, a professor of physics and astronomy, is a key member of an international team of more than 400 scientists that prepared a report on the Electron-Ion Collider, or EIC, a particle accelerator that will be built at Brookhaven National Laboratory in New York, along with a detector for capturing electron-ion collisions. Barish...
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...
An astro-statistics course University of California, Riverside, graduate student Remington O. Sexton took three years ago taught him techniques that led him to develop free, open-source code benefiting astronomers everywhere. Called BADASS, which stands for Bayesian AGN Decomposition Analysis for SDSS Spectra, the code in its current form fits astronomical spectra of active galactic nuclei...
The University of California, Riverside, is the recipient of a 2021 UC Multicampus Research Programs and Initiatives, or MRPI, award allowing the campus to put together a UC Coronavirus Assembly Research Consortium. “This consortium will aim to understand the physical principles underlying the formation of coronaviruses,” said Roya Zandi, a professor of physics and astronomy...
A team co-led by a scientist at the University of California, Riverside, has developed a method to study how HIV mutates to escape the immune system in multiple individuals, which could inform HIV vaccine design. HIV, which can lead to AIDS, evolves rapidly and attacks the body’s immune system. Genetic mutations in the virus can...
Peng Wei, an assistant professor of physics and astronomy at UC Riverside, is a co-principal investigator and theme lead on a grant from the National Science Foundation, or NSF, supported by the NSF Convergence Accelerator — a new model of innovation for the government, industry, and academia. The Massachusetts Institute of Technology, where Wei worked...
For his numerous contributions to education in science, technology, engineering, and mathematics, or STEM, Bahram Mobasher, a professor of physics and observational astronomy at UC Riverside, has been named a recipient of the Riverside Unified School District Board of Education Presidential Award for the year 2020. The Riverside Unified School District, or RUSD, educates nearly...
The UCR Department of Physics and Astronomy has been accepted to the American Physical Society Inclusion, Diversity, and Equity Alliance, or APS-IDEA, joining a consortium of physics departments, laboratories, and research collaborations committed to improving equity, diversity, and inclusion. APS-IDEA, a network of nearly 100 institutions worldwide, addresses long-standing, systemic barriers that have led to...
A top goal in cosmology is to precisely measure the total amount of matter in the universe, a daunting exercise for even the most mathematically proficient. A team led by scientists at the University of California, Riverside, has now done just that. Reporting in the Astrophysical Journal, the team determined that matter makes up 31%...
A gift made anonymously to the Department of Physics and Astronomy at UC Riverside has helped the College of Natural and Agricultural Sciences, or CNAS, in which the department is housed, meet and surpass its goal of raising $100 million toward the $300 million Living the Promise campaign, the university’s first ever comprehensive fundraising campaign...
Anew theory about the nature of dark matter helps explain why a pair of galaxies about 65 million light-years from Earth contains very little of the mysterious matter, according to a study led by a physicist at the University of California, Riverside. Dark matter is nonluminous and cannot be seen directly. Thought to make up...
A new UC Riverside study finds that climate change will have a devastating effect on the greater Palm Springs area’s dominant industry — tourism. Thousands known as “snowbirds” flock to the region annually from elsewhere in the country to escape freezing winters. However, due to climate change, the number of days above 85 degrees between...
