摘要:

HERMES-TP/SP(高能快速模块化卫星星座——技术与科学探路者,High Energy Rapid Modular Ensemble of Satellites -- Technologic and Scientific Pathfinder)是所谓分布式天文学概念的在轨演示项目。该项目被构想为由6颗搭载新型微型探测器的3U纳卫星组成的小型星座,旨在探测并精准定位伽马射线暴等明亮的高能暂现源。该星座探测器具备的宽能段、优异时间分辨率和大视场特性,是下一代具备良好定位能力的高能全天监测仪的核心特征,这类监测仪将在未来多信使天文学中发挥关键作用。在本研究中,我们将详细阐述利用空间分散的探测器对明亮暂现事件进行近乎同时观测,从而实现定位的定时技术。此外,我们还将定量讨论HERMES探路者的全天监测能力,以及其对探测到的伽马射线暴可达到的定位精度。

英文摘要:

The HERMES-TP/SP (High Energy Rapid Modular Ensemble of Satellites -- Technologic and Scientific Pathfinder) is an in-orbit demonstration of the so-called distributed astronomy concept. Conceived as a mini-constellation of six 3U nano-satellites hosting a new miniaturized detector, HERMES-TP/SP aims at the detection and accurate localisation of bright high-energy transients such as Gamma-Ray Bursts. The large energy band, the excellent temporal resolution and the wide field of view that characterize the detectors of the constellation represent the key features for the next generation high-energy all-sky monitor with good localisation capabilities that will play a pivotal role in the future of Multi-messenger Astronomy. In this work, we will describe in detail the temporal techniques that allow the localisation of bright transient events taking advantage of their almost simultaneous observation by spatially spaced detectors. Moreover, we will quantitatively discuss the all-sky monitor capabilities of the HERMES Pathfinder as well as its achievable accuracies on the localisation of the detected Gamma-Ray Bursts.
