摘要:

我们建议进行一个连续扫描的全天调查从200千电子伏至80兆电子伏实现的灵敏度,这是更好的一个因素,40或更多的相比,以前的任务,在这个能量范围内。伽马射线成像、偏振测量和光谱学(GRIPS)任务解决了欧空局宇宙愿景计划中的基本问题。在战略计划的主要主题中,GRIPS的重点是不断演变的,暴力的宇宙,探索一个独特的能量窗口。我们打算研究$γ$射线爆发和耀变体,超新星爆炸、核合成和耀变体背后的机制,银河系中正电子的神秘起源,以及极端宇宙源(包括恒星和磁星)中辐射过程和粒子加速的性质。这些非热过程的自然能量尺度为MeV量级。虽然可以使用其他方法对它们进行部分和间接的研究,但只有建议的GRIPS测量才能直接获得它们的初级光子。GRIPS将成为中微子和引力波观测站(如IceCUBE和LISA)时代瞬态源研究的驱动力,建立相对论和核天体物理学的新型诊断。这将支持外推研究恒星形成,星系演化和黑洞形成在高红移。

英文摘要:

We propose to perform a continuously scanning all-sky survey from 200 keV to 80 MeV achieving a sensitivity which is better by a factor of 40 or more compared to the previous missions in this energy range. The Gamma-Ray Imaging, Polarimetry and Spectroscopy (GRIPS) mission addresses fundamental questions in ESA's Cosmic Vision plan. Among the major themes of the strategic plan, GRIPS has its focus on the evolving, violent Universe, exploring a unique energy window. We propose to investigate $γ$-ray bursts and blazars, the mechanisms behind supernova explosions, nucleosynthesis and spallation, the enigmatic origin of positrons in our Galaxy, and the nature of radiation processes and particle acceleration in extreme cosmic sources including pulsars and magnetars. The natural energy scale for these non-thermal processes is of the order of MeV. Although they can be partially and indirectly studied using other methods, only the proposed GRIPS measurements will provide direct access to their primary photons. GRIPS will be a driver for the study of transient sources in the era of neutrino and gravitational wave observatories such as IceCUBE and LISA, establishing a new type of diagnostics in relativistic and nuclear astrophysics. This will support extrapolations to investigate star formation, galaxy evolution, and black hole formation at high redshifts.
