Shorter bursts (less than two seconds in duration) are thought to be caused by mergers of binary systems with black holes or neutron stars. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Neutron_Star_Merge_H264_High_960x540/Neutron_Star_Merge_H264_High_960x540.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Swift-Soft-Gamma-Ray-Repeater-10366-date-overlay/Swift-Soft-Gamma-Ray_Repeater-10366-date-overlay.dc.xml Swift's X-Ray Telescope (XRT) captured an apparent expanding halo around the flaring neutron star SGR J1550-5418. The halo formed as X-rays from the brightest flares scattered off of intervening dust clouds. The animation shows the glow of the halo pulsing and dispersing over six days in January 2009. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Swift-Soft-Gamma-Ray-Repeater-10366-date-overlay/Swift-Soft-Gamma-Ray_Repeater-10366-date-overlay.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/a010300_NeutronStar_NTSC/a010300_NeutronStar_NTSC.dc.xml Gamma-ray flares from SGR J1550-5418 may arise when the magnetar's surface suddenly cracks, releasing energy stored within its powerful magnetic field. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/a010300_NeutronStar_NTSC/a010300_NeutronStar_NTSC.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
