This event is now interpreted as a magnetar giant flare, more related to SGR flares than "true" gamma-ray bursts. It is the first observed SGR megaflare, a specific type of short GRB. It has been associated with the magnetar PSR B0525-66. [2]
SGR 1806−20 is a magnetar, a type of neutron star with a very powerful magnetic field, that was discovered in 1979 and identified as a soft gamma repeater.SGR 1806−20 is located about 13 kiloparsecs (42,000 light-years) [1] from Earth on the far side of the Milky Way in the constellation of Sagittarius.
The magnetar giant flare from the Large Magellanic Cloud was about 160,000 light-years from Earth. The M82 giant flare was the most distant known but not the most energetic. The one spotted in ...
First, long gamma-ray bursts are found without exception in systems with abundant recent star formation, such as in irregular galaxies and in the arms of spiral galaxies. [5] This is strong evidence of a link to massive stars, which evolve and die within a few hundred million years and are never found in regions where star formation has long ...
A magnetar is a type of neutron star with an extremely powerful magnetic field (~10 9 to 10 11 T, ~10 13 to 10 15 G). [1] The magnetic-field decay powers the emission of high- energy electromagnetic radiation , particularly X-rays and gamma rays .
SGR J1745−2900, or PSR J1745−2900, is the first-discovered magnetar orbiting the black hole Sagittarius A*, in the center of the Milky Way. [1] [2] The magnetar was discovered in 2013 using the Effelsberg 100-m Radio Telescope, the Nancay Decimetric Radio Telescope, and the Jodrell Bank Lovell Telescope.
The guidelines further provided that an emergency action plan should be initiated if a student reports signs of an allergic reaction and that such students should not be permitted to walk alone to ...
WASHINGTON (Reuters) -The U.S. Justice Department said on Tuesday that it has deleted malware planted on more than 4,200 computers by a group of criminal hackers who were backed by the People's ...
