更深更广更快的计划:追逐宇宙中最快的爆发
The Deeper Wider Faster program: chasing the fastest bursts in the Universe
摘要:
我们提出了更深更宽更快(Deeper Wider Faster,简称WFP)计划,该计划协调全球和太空中30多个多波长和多信使设施,以检测和研究快速瞬变(毫秒至数小时的持续时间)。DWF有四个主要组成部分:(1)同时观测,协调从无线电到伽马射线的大约10个主要设施,同时对同一场进行深、宽场、快节奏的观测。射电望远镜搜寻快速射电暴,而光学成像仪和高能仪器则搜寻数秒至数小时时间尺度的瞬变事件,(2)实时(秒到分钟)超级计算机数据处理和候选人识别,以及使用复杂的可视化技术对候选人进行实时(分钟)人工检查,(3)快速响应(分钟)后续光谱学和成像以及常规ToO观察,(4)建立全球1- 4米级望远镜网络进行长期跟踪。射电望远镜的主要目标是发现和研究快速射电暴和引力波事件的对应物,以及所有波长的毫秒至小时的瞬态。
英文摘要:
We present the Deeper Wider Faster (DWF) program that coordinates more than 30 multi-wavelength and multi-messenger facilities worldwide and in space to detect and study fast transients (millisecond-to-hours duration). DWF has four main components, (1) simultaneous observations, where about 10 major facilities, from radio to gamma-ray, are coordinated to perform deep, wide-field, fast-cadenced observations of the same field at the same time. Radio telescopes search for fast radio bursts while optical imagers and high-energy instruments search for seconds-to-hours timescale transient events, (2) real-time (seconds to minutes) supercomputer data processing and candidate identification, along with real-time (minutes) human inspection of candidates using sophisticated visualisation technology, (3) rapid-response (minutes) follow-up spectroscopy and imaging and conventional ToO observations, and (4) long-term follow up with a global network of 1-4m-class telescopes. The principal goals of DWF are to discover and study counterparts to fast radio bursts and gravitational wave events, along with millisecond-to-hour duration transients at all wavelengths.
