High Energy Transient Experiment

越来越明显的是，宇宙伽马射线暴(CGB)的起源只能通过识别其他能量范围内的爆发对应物来确定。到目前为止，略多于六只国债的头寸被确定为10平方弧分或更好。虽然伽马射线天文台的爆发和瞬变实验大大增加了已知爆发源的数量，并从根本上提供了关于它们在天空中分布的新信息，但它提供的源位置的精度充其量在-1度范围内。红外、光学和软X射线搜索没有发现这些CGB的任何令人信服的候选者。即使除了这样的观测传递了关于cgb源物理的重要信息外，它们原则上也可以起到弥合相对较大(-几角分大小)的伽马射线误差盒和非常小(-几角秒大小)的进行深操作…所需的盒之间的差距的重要作用。对极其微弱的静止爆发进行更多的理论搜索(25级)。对于迄今为止的所有搜索，关于可能的自然运动、假定的光学和伽马射线发射与光学瞬变事件的时间结构之间的联系的问题仍然没有得到回答。高能瞬变实验项目是在国际上组织的，旨在达成一种综合的方法来解决关于黑洞和其他天文瞬变的这些和其他基本问题。考虑到这些情况，该项目推动了国际专用卫星的发展，该卫星包括三台科学仪器：全向伽马射线能谱仪(FRANSE-CESR)、广场X射线监测器(JAPAN-RIKEN)和紫外线瞬变相机阵列。(美国-麻省理工学院)这颗卫星计划于1995年4-5月由美国宇航局飞马火箭发射。我们必须在国际上交流各种信息来推广这颗卫星。我们召开会议并进行测试，以调整仪器的协作和接口。较少

It has become increasingly apparent that origin of cosmic gamma-ray bursts (CGBs) can only be determined by identifying burster counterparts in other energy ranges. To date, slightly over half a dozen CGBs have positions determined to 10 square arc-minutes or better. Although the burst and transient experiment on the Gamma-Ray Observatory are greatly increasing the number of known burst sources and provide fundamentally new information on their distribution over the sky, the accuracy of source locations it provides to be at best in the -1 degree range. Infrared, optical and soft X-ray searches have not revealed any convincing candidates for these CGBs. Even apart from the important information which such observations convey about the physics of CGB sources, they can in principle serve the important function of bridging the gap between the relatively large (-several arc-minutes in size) gamma-ray error boxes and the very small (-a few arc-seconds in size) boxes needed to conduct deep op … More tical searches (> 25th magnitude) for the exceedingly faint quiescent burster counterparts. For all searches to date, questions concerning possible proper motion, the association between the putative optical and gamma-ray emission and the time structure of the optical transient event, remain unanswered. The high energy transient experiment project was internationally organized to reach an integrated approach to resolving these and other fundamental questions about CGBs and other astronomical transients.Considering these situations, this project promotes the international specific satellite which contains three scientific instruments ; an omnidirectional gamma-ray spectrometer (France-CESR), a wide-field X-ray monitor (Japan- RIKEN), and an ultraviolet transient camera array. (USA-MIT) This satellite is scheduled to be launched by NASA Pegasus rocket in April-May, 1995. We have to communicate various information internationally to promote this satellite. We have meetings and do tests to adjust collaboration and interfaces of instruments. Less
