| 摘 要： | 伽马射线暴是宇宙中最剧烈的爆发现象之一.Swift卫星的快速定位和Fermi卫星的宽、高能段观测,使得伽马暴的观测可以全波段进行.通过Swift的观测可以对伽马暴现象的本质有进一步的理解,而Fermi卫星提供了一些暴高能光子的辐射数据,为进一步研究暴的辐射机制和伽马暴以及它的余辉提供了有力的依据.介绍了Swift和Fermi卫星发射后一些伽马暴的观测和理论研究进展.

| Abstract: | Gamma-ray bursts(GRBs) are the most luminous phenomenon in the universe, and their origin and mechanism are very active areas of research and debate.Through nearly forty years development,today,gamma-ray bursts are accessible in full time window and in all electromagnetic wavelengths of the events,with the satellites Swift and Fermi.Swift,the NASA's dedicated GRB emission,was launched on 20th November 2004.With three instruments,Bursts Alert Telescope(BAT),X-ray Telescope(XRT) and UV-Optical Telescope(UVOT)... |
