光学天气望远镜:科学新前沿

Optical Synoptic Telescopes: New Science Frontiers

J. Anthony Tyson

摘要:

在过去的十年里,像斯隆数字巡天这样的巡天观测已经证明了大型数据集在回答基本天体物理学问题方面的力量。这一观测上的进步,基于望远镜建设、探测器和信息技术的协同进步,对几乎所有的天文学领域和基础物理学领域都产生了巨大的影响。下一代仪器以及将使用它们进行的调查将保持这一革命性进展。硬件和计算技术的挑战以及令人兴奋的科学机会正在吸引来自天文学,光学,微光探测器,高能物理,统计学和计算机科学的科学家和工程师。天文学的历史一再告诉我们,每当我们以一种新的方式观察天空时,总会有惊喜。新一代的巡天发现尤其如此。来自具有足够光学扩展量的大型地面主动光学望远镜的成像数据可以同时用于许多科学任务。这些新的研究将依赖于数十亿物体的统计精度。这将是第一次对整个天空进行深入而快速的调查,为宇宙中微弱的移动和遥远的爆炸物体打开一扇新的窗户,并揭开暗能量的神秘面纱。

英文摘要:

Over the past decade, sky surveys such as the Sloan Digital Sky Survey have proven the power of large data sets for answering fundamental astrophysical questions. This observational progress, based on a synergy of advances in telescope construction, detectors, and information technology, has had a dramatic impact on nearly all fields of astronomy, and areas of fundamental physics. The next-generation instruments, and the surveys that will be made with them, will maintain this revolutionary progress. The hardware and computational technical challenges and the exciting science opportunities are attracting scientists and engineers from astronomy, optics, low-light-level detectors, high-energy physics, statistics, and computer science. The history of astronomy has taught us repeatedly that there are surprises whenever we view the sky in a new way. This will be particularly true of discoveries emerging from a new generation of sky surveys. Imaging data from large ground-based active optics telescopes with sufficient etendue can address many scientific missions simultaneously. These new investigations will rely on the statistical precision obtainable with billions of objects. For the first time, the full sky will be surveyed deep and fast, opening a new window on a universe of faint moving and distant exploding objects as well as unraveling the mystery of dark energy.
