GRB随访和科学与THESEUS/IRT
GRB follow-up and science with THESEUS/IRT
摘要：
空间飞行任务概念\theseus ~的目的是继续收集和研究像\swift这样的伽马射线暴事件。它将使我们能够研究早期的宇宙。此外，它将为我们提供前所未有的灵敏度研究伽玛暴辐射和测量红移的$z>5$的爆发。在这项工作中，我们调查的优势，光学和近红外望远镜安装在同一颗卫星上，是由伽玛暴像\theseus /IRT触发。之后，我们调查可能的未来发展在伽玛射线暴科学，首先为即时阶段和余辉阶段。我们发现，超过一半的来源检测到的\theseus，将永远不会看到从地面望远镜。此外，所有可观测源中只有$\sim50\%$在一小时内可见，即所有\theseus ~瞬变源中的$<30\%$。只有通过望远镜网络才能获得更多的可观测源。\theseus ~将允许探测最长伽玛暴的近红外瞬发相，增加从伽马射线到近红外的研究事件的数量，从目前研究的少数事件增加到每年研究$\gtrsim10$伽玛暴。
英文摘要：
The aim of the space mission concept \theseus~is to continue to collect and study the GRB events like \swift. It will allow us to study the early Universe. Moreover, it will offer us to study with unprecedented sensitivity GRB emission and to measure the redshift for the bursts with $z>5$. In this work, we investigate the advantages of a optical and near-infrared telescope mounted on the same satellite that is triggered by the GRB like \theseus/IRT. Afterwards, we investigate the possible future developments in the GRB science, first for the prompt phase and the for afterglow phase. We find that more than half of the sources detected by \theseus, and will never be visible from a a ground-based telescope. Moreover, only $\sim50\%$ of all observable sources are visible within one hour, i.e. $<30\%$ of all \theseus~transient sources. A higher number of observable sources can only be achieved with a network of telescopes. \theseus~will permit to detect the NIR prompt phase of the longest GRBs, increasing the number of events studied from gamma-rays to the near-infrared from a handful of events studied up to now to $\gtrsim10$ GRBs per year.
