Higgs Boson, Nebulae and Star Clusters Form Part of UA Public Night

William Keel has spent several years listening for the gasp – the sound a 6-year-old makes as he sees Saturn with his own wide eyes. When Keel hears this sound, he knows a young boy’s textbook-limited ideas about the cosmos have just transformed.

A Solution for Predicting Thirring Model Interactions of Relativistic Fermions

A major challenge for physics in the last century was connecting two of its leading theories – quantum physics and special relativity. Researchers are still grappling with the relativistic quantum theories that resulted. Writing in Physical Review Letters, CQT researchers propose a solution to one outstanding problem: how to make predictions from the Thirring Model.

Solid-State Refrigerator Uses Quantum Physics to Cool Large Objects to Extremely Low Temperatures

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures.

New Ultraviolet Telescope to Trace Source of Ultra High-Energy Cosmic Rays

The National Aeronautics and Space Administration has awarded $4.4 million to a collaboration of scientists at five U.S. universities and NASA's Marshall Space Flight Center to help build a telescope for deployment on the International Space Station in 2017.

Attosecond Science May Help Control Quantum Nature of the Electron

In the blink of an eye, more attoseconds have expired than the age of Earth measured in – minutes. A lot more. To be precise, an attosecond is one billionth of a billionth of a second.

Young-Looking Supernova Found in Old Galaxy

The star Eta Carinae is ready to blow. 170 years ago, this 100-solar-mass object belched out several suns' worth of gas in an eruption that made it the second-brightest star after Sirius. That was just a precursor to the main event, since it will eventually go supernova.

Astronomers Refine Astronomical Calculation That Helps Measure Expansion of the Universe

A team of astronomers including Carnegie’s Ian Thompson have managed to improve the measurement of the distance to our nearest neighbor galaxy and, in the process, refine an astronomical calculation that helps measure the expansion of the universe. Their work is published March 7 by Nature.
