摘要:

切伦科夫望远镜阵列(CTA)将是下一代甚高能(VHE)伽马射线天文学的地面观测站,部署了数十台高灵敏度和快速反应的切伦科夫望远镜。它将覆盖广泛的能量范围(20 GeV - 300 TeV),具有前所未有的灵敏度。为了使科学回报最大化,将向观测站提供一个在线软件系统,该系统将对科学数据进行首次实时分析。这项研究调查了用于短期探测伽马射线源的现有科学工具和分析技术的精确度和准确度,包括天空定位、探测重要性以及如果实现重要探测,对积分光子通量的初步估计。范围是评估算法的实现在CTA的实时分析的可行性。在这方面的贡献,我们提出了一个总体概述的方法和一些结果的测试情况下的短期检测的伽马射线暴余辉,作为VHE对应的引力波事件。

英文摘要:

The Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for very-high-energy (VHE) gamma-ray astronomy, with the deployment of tens of highly sensitive and fast-reacting Cherenkov telescopes. It will cover a wide energy range (20 GeV - 300 TeV) with unprecedented sensitivity. To maximize the scientific return, the observatory will be provided with an online software system that will perform the first analysis of scientific data in real-time. This study investigates the precision and accuracy of available science tools and analysis techniques for the short-term detection of gamma-ray sources, in terms of sky localization, detection significance and, if significant detection is achieved, a first estimation of the integral photon flux. The scope is to evaluate the feasibility of the algorithms' implementation in the real-time analysis of CTA. In this contribution we present a general overview of the methods and some of the results for the test case of the short-term detection of a gamma-ray burst afterglow, as the VHE counterpart of a gravitational wave event.
