Lorenzo Amati, Paul T. O'Brien, Diego Götz, Enrico Bozzo, Andrea Santangelo

摘要:

THESEUS是一项空间飞行任务概念,目前正由欧空局作为候选M5飞行任务进行A阶段研究,目的是利用伽马射线暴研究早期宇宙,并在多信使和时域天体物理学方面取得重大进展。除了充分利用高红移伽玛暴的宇宙学(pop-III恒星,宇宙再电离,SFR和金属丰度演化到“宇宙黎明”),THESEUS将允许识别和研究引力波源的电磁对应物,这些电磁对应物将在20年代末/30年代初由下一代设施如aLIGO/aVirgo,LISA,KAGRA,和爱因斯坦望远镜(ET),以及大多数类别的X/伽马射线瞬态源,从而提供了一个理想的协同作用,与大的e.m.不久的将来的设施,例如,LSST,ELT,TMT,SKA,CTA,ATHENA。这些突破性的科学目标将通过前所未有的X/伽马射线监测器的组合来实现,这些监测器提供了探测和准确定位伽马射线暴的能力,并提供了在0.1 keV - 10 MeV的能量带内的多种瞬态,同时机载近红外望远镜提供了对近红外对应物的探测、定位(arcsec)和红移测量。还设想了一个客座观察员方案,以进一步改善科学回报和社区参与。我们总结了任务的主要科学要求,并概述了更新的概念,设计(仪器和航天器)和任务概况。

英文摘要:

THESEUS is a space mission concept, currently under Phase A study by ESA as candidate M5 mission, aiming at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domain astrophysics. In addition to fully exploiting high-redshift GRBs for cosmology (pop-III stars, cosmic re-ionization, SFR and metallicity evolution up to the "cosmic dawn"), THESEUS will allow the identification and study of the electromagnetic counterparts to sources of gravitational waves which will be routinely detected in the late '20s / early '30s by next generation facilities like aLIGO/aVirgo, LISA, KAGRA, and Einstein Telescope (ET), as well as of most classes of X/gamma-ray transient sources, thus providing an ideal synergy with the large e.m. facilities of the near future like, e.g., LSST, ELT, TMT, SKA, CTA, ATHENA. These breakthrough scientific objectives will be achieved by an unprecedented combination of X/gamma-ray monitors, providing the capabilities of detecting and accurately localize and kind of GRBs and may classes of transient in an energy band as large as 0.1 keV - 10 MeV, with an on-board NIR telescope providing detection, localization (arcsec) and redshift measurement of the NIR counterpart. A Guest Observer programme, further improving the scientific return and community involvement is also envisaged. We summarize the main scientific requirements of the mission and provide an overview of the updated concept, design (instruments and spacecraft) and mission profile.
