Less than 2 seconds is not a lot of time to find the burst and capture some data. These images show the merger of two neutron stars recently simulated using a new supercomputer model. Redder colors indicate lower densities. Green and white ribbons and lines represent magnetic fields. The orbiting neutron stars rapidly lose energy by emitting gravitational waves and merge after about three orbits, or in less than 8 milliseconds. The merger amplifies and scrambles the merged magnetic field. A black hole forms and the magnetic field becomes more organized, eventually producing structures capable of supporting the jets that power short gamma-ray bursts. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/534058main_NS_six_panel_17/534058main_NS_six_panel_17.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
