SGR 0501+4516 : ウィキペディア英語版
SGR 0501+4516
SGR 0501+4516 is a soft gamma repeater (SGR), and is an ancient stellar remnant. Currently, the phenomenons of SGRs and the related Anomalous X-ray pulsars (AXP) are explained as arising from magnetars. SGR 0501+4516 is located approximately 15,000 light years from Earth and has a magnetic field 100 trillion times stronger than the Earth’s.〔http://www.nasa.gov/mission_pages/swift/bursts/magnetar_europe.html〕
SGR 0501+4516 is remarkable in that it has been the first SGR to have been discovered after ten years without SGR detections.〔N. Rea, G. L. Israel, R. Turoll et al., ''The first outburst of the new magnetar candidate SGR 0501+4516'', Monthly Notices of the Royal Astronomical Society, Volume 396, Issue 4, pages 2419–2432, July 2009, DOI:10.1111/j.1365-2966.2009.14920.x, (arXiv:0904.2413 )〕
It has been suggested that SGR 0501+4516, together with 1E 1547.0-5408, should be considered as tools for a final unification of SGRs, AXPs and the “transient AXPs (TAXPs)” into a single class of “magnetars candidates”.〔
==Discovery==
Its existence has been reported on Aug. 22, 2008, by NASA's Swift satellite, which reported numerous blasts of radiation from the object. The eruptions has been subsequently in-depth studied using the European Space Agency's XMM-Newton and International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellites.〔 The object had been ''serendipitously'' observed before in 1992 by ROSAT.〔
