Gamma-ray Burst
2014-05-01 04:41:32

redOrbit Staff & Wire Reports - Your Universe Online An international team of astronomers has for the first time measured circular polarization in the afterglow of gamma-ray bursts, the powerful flashes of radiation originating from massive dying stars as they collapse into black holes. A massive star explodes as a supernova when it dies, and its core collapses into a black hole, scientists from the Niels Bohr Institute explained in a statement Wednesday. In rare instances, a jet is...

Ultra Sensitive Detection Of Radio Waves Using Lasers
2014-03-05 14:30:33

University of Copenhagen - Niels Bohr Institute Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme...

Decay Used To Create Quantum Information
2013-11-25 09:47:26

University of Copenhagen - Niels Bohr Institute Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at the Niels Bohr Institute, among others, have flipped things around and are exploiting the decay to create the so-called entanglement of atomic systems, which is the foundation for quantum information processing. The results are published in the scientific journal, Nature. "When working with...

Resonance In 'Artificial Atoms' Control Quantum Communication
2013-08-06 12:26:15

University of Copenhagen - Niels Bohr Institute Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters. In a conventional computer, information is made up of bits, comprised of 0's and 1's. In a quantum...

Black Holes Physics Described By Researchers
2012-12-12 09:42:37

April Flowers for redOrbit.com - Your Universe Online Many mysteries surround black holes, but new research led by the Niels Bohr Institute has come up with groundbreaking new theories that might explain several of their more mysterious properties. The new study reveals that black holes have properties that resemble the dynamics of both solids and liquids. Black holes are extremely compact, so compact in fact that they generate an incredibly strong gravitational pull. Everything that...

Dark Matter Mystery Close To Being Solved
2012-09-05 05:25:36

April Flowers for redOrbit.com - Your Universe Online Dark matter comprises a large portion of the Universe, filling the space between galaxies and stars. Since the prediction of dark matter some 70 years ago, researchers from a myriad of disciplines — astronomers, cosmologists, and even particle physicists — have been looking for answers to what dark matter could be. New observations from the Planck satellite may bring researchers from the Niels Bohr Institute closer than...

Baby Galaxies Grew Up Faster Than Previously Believed
2012-05-18 03:53:28

[ Watch the Video ] Baby galaxies from the young Universe more than 12 billion years ago evolved faster than previously thought, shows new research from the Niels Bohr Institute. This means that already in the early history of the Universe, there was potential for planet formation and life. The research results have been published in the scientific journal, Monthly Notices of the Royal Astronomical Society Letters. For several thousand years after the Big Bang 13.7 billion years ago,...

Researchers at the Niels Bohr Institute have combined two worlds — quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new cooling method works quite paradoxically by heating the material! Using lasers, researchers...

Image 1 - Ancient Stars Hint At Prehistory Of The Milky Way
2011-11-16 03:58:29

Some of the oldest stars in the Milky Way — a kind of stellar fossils in the outer reaches of our galaxy, contain abnormally large amounts of heavy elements like gold, platinum and uranium. Where these large amounts came from has been a mystery for researchers, since they are usually seen in much later generations of stars. Researchers at the Niels Bohr Institute have been studying these ancient stars for several years with ESO's giant telescopes in Chile in order to trace the origin of...

Image 1 - New Record For Measurement Of Atomic Lifetime
2011-09-08 05:40:30

  Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new measurements show a lifetime of 2050 seconds, which corresponds to approximately ½ hour. This is the longest lifetime ever measured in a laboratory. The results have been published in the scientific journal Physical Review Letters. The experiment...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
