Abstract

TUS (Tracking Ultraviolet Set-up), the first orbital telescope of ultra-high energy cosmic rays (UHECRs), has demonstrated that instruments of this kind have much broader capabilities and can also detect various transient luminous events, meteors, anthropogenic glow and other processes taking place in Earth atmosphere in the UV frequency range. In this short paper, we address the question whether an orbital detector of UHECRs can also register gamma-ray bursts (GRBs) via the fluorescent glow of irradiated nocturnal atmosphere. We analyse the latest Fermi GBM catalog of GRBs and properties of several active and perspective instruments. The study reveals that even an avanced detector with parameters of an optical system similar to that of the KLYPVE-EUSO (K-EUSO) or POEMMA telescopes and an appropriate trigger tuned to register events that evolve much slower than an extensive air shower, has very modest capabilities in this respect and will be able to observe only a few GRBs per year of operation.

用超高能宇宙射线轨道探测器观测伽马射线暴的前景。

摘要

第一台超高能宇宙射线（UHECR）轨道望远镜TUS（跟踪紫外线装置）已证明这种仪器具有更广泛的功能，还可以检测各种瞬时发光事件，流星，人为辉光和其他过程发生在地球大气中的紫外线频率范围内。在这篇简短的论文中，我们解决了一个问题：UHECR的轨道探测器是否也可以通过辐射的夜间大气的荧光辉光来记录伽马射线暴（GRB）。我们分析了GRB的最新Fermi GBM目录以及一些主动和透视仪器的属性。
