UC Davis Astronomers Help Uncover the Farthest Star Ever Seen

April 02, 2018

Through a lucky quirk of nature, astronomers have used the Hubble Space Telescope to view a single star halfway across the universe. Nine billion light years from Earth, the giant blue-white star, nicknamed “Icarus” by the team, is by far the most distant individual star ever seen. Marusa Bradac, a physics professor and astronomer at UC Davis and graduate student Austin Hoag are part of the team describing Icarus and another distant, magnified star in two papers published April 2 in the journal Nature Astronomy.

DarkSide-50 Collaboration Sets Stage for Next Experiment

February 22, 2018
The DarkSide-50 experiment at the Gran Sasso National Laboratory in Italy has completed its experimental run. Four UC Davis physicists – Associate Professor Emilija Pantic, postdoctoral researchers Tessa Johnson and Luca Pagani, and graduate student Ben Schlitzer – are members of the DarkSide-50 research collaboration.

Doing Without Dark Energy

December 13, 2017
Mathematicians Blake Temple and Zeke Vogler at the University of California, Davis, and Joel Smoller at the University of Michigan, Ann Arbor, worked out solutions to General Relativity without invoking dark energy. They argue that the equations show that the Friedmann space-time is actually unstable: Any perturbation — for example if the density of matter is a bit lower than average — pushes it over into an accelerating universe.

Rising Star: The Center for Quantum Mathematics and Physics

November 13, 2017
With the Center for Quantum Mathematics and Physics (QMAP), the college is creating an extraordinary environment where mathematicians and physicists will work side-by-side to explore quantum field theory, string theory, and quantum gravity.

New Technique Makes Light Metallic Nanofoam

November 02, 2017
A simple method for manufacturing extremely low-density palladium nanofoams could help advance hydrogen storage technologies, reports a new study from researchers in the UC Davis College of Letters and Science.

UC Davis Helps Spot Colliding Neutron Stars, An Astronomical Breakthrough

October 16, 2017
For the first time, astronomers have observed a celestial event through both conventional telescopes and gravitational waves. Assistant Professor Stefano Valenti helped detect the collision of two neutron stars and confirm these cataclysmic events are the source of gold, platinum and other heavy elements.
