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.
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.
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 .
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 ...
The numbers give the position in the sky, for example, SGR 0525-66 has a right ascension of 5h25m and a declination of −66°. The date of discovery sometimes appears in a format such as 1979/1986 to refer to the year the object was discovered, in addition to the year soft gamma repeaters were recognized as a separate class of objects rather than "normal" gamma-ray bursts.
SGR 1935+2154 (or SGR J1935+2154) is a soft gamma repeater (SGR) that is an ancient stellar remnant, in the constellation Vulpecula, originally discovered in 2014 by the Neil Gehrels Swift Observatory. [4]
Anomalous X-ray pulsar (AXP) 1E 1048.1-5937 was the first AXP ever observed to emit an SGR-like X-ray burst. [2] It is also the closest magnetar to Earth located 2,759 parsecs (9,000 light-years) away in the constellation Carina .
