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...

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. Illustration of the EGS77 galaxy group...

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...

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...

Small magnets reveal big secrets

An international research team led by a physicist at the University of California, Riverside, has identified a microscopic process of electron spin dynamics in nanoparticles that could impact the design of applications in medicine, quantum computation, and spintronics. Magnetic nanoparticles and nanodevices have several applications in medicine — such as drug delivery and MRI —...

UCR Physics and Astronomy at the Long Night of Arts and Innovation

A team from UCR Physics & Astronomy participated in this year’s Long Night of Arts and Innovation. Our mission was to foster scientific literacy and to generate excitement for science among kids and adults who came to this major outreach event in downtown Riverside. Students from the Astro Club and the SPS brought a telescope...

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 hosting active galactic nuclei that have spatially extended outflows. (SDSS) Dwarf galaxies are small galaxies that...

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...

Astronomers discover triplet of black holes on collision course

Three giant black holes have been spotted within a titanic collision of three galaxies, according to data captured by several telescopes including NASA’s Chandra X-ray Observatory. “Identifying the three active black holes, or active galactic nuclei, in this system was like putting together a puzzle,” said Gabriela Canalizo , a professor of physics and astronomy...

Physicists present results from updated search for new invisible particles

Physicists Bill Gary and Owen Long , members of the Compact Muon Solenoid, or CMS, Collaboration at the Large Hadron Collider, or LHC, at CERN, recently completed a “legacy” analysis from the LHC Run 2, the first high-energy run of the LHC. The CMS experiment is a large particle-capturing detector at CERN. The research paper...

Science and art mesh in the life and work of this experimental physicist.

Nathan Gabor hadn’t always planned on becoming a scientist. Walk into the office of the 38-year-old experimental physicist, and you’ll be greeted with an intricate robot sculpture on his desk and psychedelic artwork on the walls, all of which are his creations. Now an associate professor of physics, Gabor was originally on the path to...

Grant to physicist gives study of strongly interacting systems a boost

A physicist at the University of California, Riverside, has received a grant of about $523,000 from the U.S. Department of Energy to study the possible emergent behavior of “strongly interacting systems,” an important area of focus in solid-state physics. Specifically, when the repulsive Coulomb force between electrons in a solid becomes strong, new behaviors —...

Physicists’ finding could revolutionize information transmission

Move aside, electrons; it’s time to make way for the trion. A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor — ultraclean single-layer tungsten diselenide (WSe 2 ) — a feat that could increase the capacity and alter the form of information...
