Fermi was launched June 11, at pm EDT. Congratulations to Dr. On Aug. Lasting only about a second, it turned out to be one for the record books - the shortest gamma-ray burst GRB caused by the death of a massive star ever seen.
When the repairs are completed, the backlog of data will be processed and posted to the Fermi Science Support Center. To best understand what energy frequencies they see, here's a quick explanation of an electronvolt eV. An electronvolt is defined as how much energy a single electron gains when its electric potential increases by one volt, according to Encyclopedia Britannica. Electric potential is the amount of work to move a unit charge from one spot to another against an electric field.
Visible light has a photon energy of between 1. The scale for electronvolts continues as follows: kilo-electron volt keV, one thousand eV , mega-electron volt MeV, one million eV , giga-electron volt GeV, one thousand million eV , etc.
For a quick idea of how much energy we're talking about, a single nuclear fission event is measured at about MeV, according to the Lawrence Berkeley National Laboratory.
Fermi can view objects at a wide range of scales — anywhere between 8 keV to GeV. The GBM can view the entire sky and is designed to spot about gamma-ray bursts every year, as well as events such as solar flares.
It detects X-rays and gamma-rays that have an energy range between 8 keV and 30 meV, Goddard says. The LAT can view 20 percent of the sky at once, and if it is left in its default "sky-survey" mode, it will move around the entire sky once every three hours.
Researchers can also choose to swing the LAT to view interesting objects. Fermi discovered two massive bubbles of material emanating from the Milky Way's center in Follow-up observations have been performed in X-rays and radio wavelengths, including a Hubble Space Telescope study released in that clocked these bubbles moving at 2 million mph 3. NASA periodically releases all-sky maps from Fermi taken over several years of observations, such as this version that had two years of data included.
More than a third of the sources revealed in this particular map had never been detected before. Also in , Fermi released a large scientific haul of results including nine newly discovered pulsars and spotted a mysterious burst near the Crab Nebula. Fermi became a U. In , he returned to the University of Chicago as a professor at the Institute of Nuclear Studies, which now bears his name--Fermi Institute.
He resumed his fundamental research interests in nuclear and elementary particle physics and also, beginning in , served as one of the first members of the General Advisory Committee of the Atomic Energy Commission.
On November 16, , President Eisenhower and the Atomic Energy Commission gave Fermi a special award for his lifetime of accomplishments in physics and, in particular, for the development of atomic energy. Fermi's other research resulted in the Fermi-Dirac particle statistics, the theory of beta-decay, the Thomas-Fermi model of the atom, and a theory of the origin of cosmic rays.
Fermi died on November 28, , and the Enrico Fermi Award was established in to perpetuate the memory of his brilliance as a scientist and to recognize others of his kind-inspiring others by his example.
Thank you for visiting our site. It got replaced by a Ti but still lives in a hand-me-down computer. Nvidia got Partial DX12 support for these cards a month or two ago That's awesome they did that prior to putting them to legacy I use a GTX on one of my pc's It's still faster than a but slower than a That imo is incredible. Ready to cook dinner, heat the house and play Crysis. At least i was not so stupid to buy these slow expensive Nvidia cars back then. Xaled overrated, overpriced products lol, i guess actual benchmarks means overrated :P overpriced maybe but thats retailers fault, not Nvidia.
