论文摘要
我们提出了达克沙（Daksha），这是一种用于研究重力波源电磁对应物和伽马射线爆发的高能量瞬变任务。达克沙（Daksha）将在地球对面的低地赤道轨道中包含两个卫星。每个卫星将携带三种类型的探测器，以覆盖整个天空的能量范围从1 KEV到> 1 MEV。在发现后几分钟内，在板载上检测到的任何瞬态将公开宣布。所有光子数据将在地面站通行中下载，以获得源位置，光谱和光曲线。此外，达克沙（Daksha）将解决各种科学案例，包括监测X射线脉冲星，磁铁研究，太阳能耀斑的研究，搜索快速无线电爆发对应物，常规监测明亮的持续持续的高能源，地面伽马射线闪光以及通过镜头探测原始黑洞的探测。在本文中，我们讨论了Daksha的技术能力，而详细的科学案例是在另一篇论文中讨论的。
We present Daksha, a proposed high energy transients mission for the study of electromagnetic counterparts of gravitational wave sources, and gamma ray bursts. Daksha will comprise of two satellites in low earth equatorial orbits, on opposite sides of earth. Each satellite will carry three types of detectors to cover the entire sky in an energy range from 1 keV to >1 MeV. Any transients detected on-board will be announced publicly within minutes of discovery. All photon data will be downloaded in ground station passes to obtain source positions, spectra, and light curves. In addition, Daksha will address a wide range of science cases including monitoring X-ray pulsars, studies of magnetars, solar flares, searches for fast radio burst counterparts, routine monitoring of bright persistent high energy sources, terrestrial gamma-ray flashes, and probing primordial black hole abundances through lensing. In this paper, we discuss the technical capabilities of Daksha, while the detailed science case is discussed in a separate paper.
