Gravitational Lenses Expose Starburst Galaxies in the Early Universe

Some of the brightest galaxies in the universe – infant galaxies that churned out tens of thousands of stars each year at the dawn of the universe – evolved much sooner and in greater numbers than previously thought, according to new measurements obtained by University of Arizona astronomers.

Telescope Observations Reveal Star-Forming Galaxies

When a batch of bright cosmic objects first appeared in maps in 2008 made with data from the South Pole Telescope, astronomers at the University of Chicago’s Kavli Institute for Cosmological Physics regarded it only as an unavoidable nuisance.

Tackling Challenges in Accelerator Science Sparks Solutions for Science, Industry, and More

Some would call the Relativistic Heavy Ion Collider (RHIC) — an "atom smasher" at the U.S. Department of Energy's Brookhaven National Laboratory — the most modern accelerator facility in the world.

Feynman's Methodology Shows Particle-Wave Duality of Electrons

The precise methodology of Richard Feynman's famous double-slit thought-experiment – a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave – has been followed in full for the very first time.

NASA Discovers a Pair of Brown Dwarfs

NASA's Wide-field Infrared Survey Explorer (WISE) has discovered a pair of stars that has taken over the title for the third-closest star system to the sun. The duo is the closest star system discovered since 1916.

UAHuntville to Participate in NASA Mission to Investigate Highest Energy Cosmic Rays

The University of Alabama in Huntsville (UAHuntville) has been selected by NASA to participate in a mission designed to investigate the highest energy cosmic rays, single sub-atomic particles, each with as much kinetic energy as a major league pitcher’s fastball.

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.
