Physicists have seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons to be ripped from their cores, accelerated, and then smashed back into the cores they left behind. This recollision produced multiple frequencies of light simultaneously.
The pulsar at the center of the famous Crab Nebula is a veritable bundle of energy. Astronomers observed the pulsar in the area of very high energy gamma radiation from 25 up to 400 gigaelectronvolts (GeV), a region that was previously difficult to access with high energy instruments, and discovered that it actually emits pulses with the maximum energy of up to 400 GeV -- 50 to 100 times higher than theorists thought possible. These latest observations are difficult for astrophysicists to explain.
First spectroscopic results from BOSS give the most detailed look yet at the time when dark energy turned on some six billion light years ago, as the expansion of the universe was slipping from the grasp of matter
(PhysOrg.com) -- Since its discovery in 2004, graphene -- sheets of carbon an atom thick -- has sparked a flurry of research into the nanomaterial
(PhysOrg.com) -- Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out and its density decreased, dark energy took over and expansion began to accelerate.
(PhysOrg.com) -- Physicists at the University of California, San Diego have discovered patterns which underlie the properties of a new state of matter.
