How a virus forms its symmetric shells

Viruses — small disease-causing parasites that can infect all types of life forms — have been well studied, but many mysteries linger. One such mystery is how a spherical virus circumvents energy barriers to form symmetric shells. A research team led by physicist Roya Zandi at the University of California, Riverside, has made progress is...

New work has potential to accelerate development of nanotechnology

Nanoscale technology has greatly improved our daily lives with products such as computers, phones, and solar cells. To develop the next-generation nanotechnology, new classes of materials need to be explored. Two-dimensional “valley semiconductors,” such as monolayer molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), have remarkable properties and novel applications. When these materials absorb light, some...

Astronomers discover unusual monster galaxy in the very early universe

An international team of astronomers led by scientists at the University of California, Riverside, has found an unusual monster galaxy that existed about 12 billion years ago, when the universe was only 1.8 billion years old. Dubbed XMM-2599, the galaxy formed stars at a high rate and then died. Why it suddenly stopped forming stars...

NSF CAREER Award supports astronomer’s quest to further understand the universe

Laura Sales first fell in love with astronomy when she was in middle school in Argentina, her country of birth. Today, she is an assistant professor of physics and astronomy at UC Riverside and the recipient of the National Science Foundation’s prestigious Faculty Early Career Development (CAREER) Award, one of the most coveted recognitions a...

Detection of very high frequency magnetic resonance could revolutionize electronics

A team of physicists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and enhance sensitivity. Terahertz is a unit of electromagnetic wave frequency: One gigahertz equals 1 billion hertz; 1 terahertz equals 1,000 gigahertz. The higher the...

UC Riverside physicists to set up experiments at new nuclear physics facility

Earlier this month, the U.S. Department of Energy announced the selection of Brookhaven National Laboratory in Upton, NY, as the site for Electron Ion Collider, or EIC, a planned major new nuclear physics research facility. The EIC, which will be designed and constructed over ten years, will explore mysteries of the “strong force” that binds...

Astronomers find farthest galaxy group identified to date

Bahram Mobasher, a professor of observational astronomy at UC Riverside, is a member of an international team of astronomers that found the farthest galaxy group identified to date. Called EGS77, the group of three galaxies dates to a time when the universe was only 680 million years old. While more distant galaxies have been observed...

Gamma-ray laser moves a step closer to reality

A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser, which may have applications in medical imaging, spacecraft propulsion, and cancer treatment. Extremely short-lived and only...

Simple experiment explains magnetic resonance

Physicists at University of California, Riverside, have designed an experiment to explain the concept of magnetic resonance. The project was carried out by undergraduate students in collaboration with local high school teachers. A versatile technique employed in chemistry, physics, and materials research, magnetic resonance describes a resonant excitation of electron or atomic nuclei spins residing...

Probing boosted dark matter

Last month, the U.S. Department of Energy’s Fermi National Accelerator Laboratory joined with its international partners to break ground on a new beamline that will help scientists learn more about ghostly particles called neutrinos. The beamline is part of the Long-Baseline Neutrino Facility which will house the Deep Underground Neutrino Experiment, or DUNE, an international...

New research finding gives valleytronics a boost

An international research team led by physicists at the University of California, Riverside, has revealed a new quantum process in valleytronics that can speed up the development of this fairly new technology. Valleytronics, a portmanteau of “valley” and “electronics,” uses local energy minima — or valleys — in the electronic band structure of semiconductors. Current...

Black holes stunt growth of dwarf galaxies

Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation. Dwarf galaxies are small galaxies that contain between 100 million to a few billion stars. In contrast, the...

The Milky Way kidnapped several tiny galaxies from its neighbor

Just like the moon orbits the Earth, and the Earth orbits the sun, galaxies orbit each other according to the predictions of cosmology. For example, more than 50 discovered satellite galaxies orbit our own galaxy, the Milky Way. The largest of these is the Large Magellanic Cloud, or LMC, a large dwarf galaxy that resembles...
