Parkes observations for project P1066 semester 2021APRS_27

We propose 36 hrs of Parkes observations to continue our successful Deeper, Wider, Faster (DWF) program to detect fast transients and fast radio burst (FRB) counterparts and help resolve their nature. DWF coordinates over 80 observatories worldwide at all wavelengths, from radio to gamma-ray to detect and follow-up FRBs and other elusive fast (millisecond-to-hours duration) transients. Crucially, we coordinate simultaneous deep, fast-cadenced, wide-field observations at all wavelengths to observe the same field at the same time as Parkes, enabling multi-wavelength detection before, during, and after the radio detection. Little to no multi-wavelength observations to any significant depth have been done on these timescales, leaving this parameter space underexplored. DWF coordinates major facilities to observe with Parkes, such as South Pole Telescope (mm/sub-mm), GROND (infrared), CTIO Dark Energy Camera (optical), Astrosat (UV/X-ray), HXMT (X-ray), HESS (gamma-ray), and Pierre Auger (high-energy). We perform realtime data processing and transient identification at all wavelengths that enables triggering our deep, rapid-response (within minutes) follow up programs for deep spectroscopy and imaging using the world's largest telescopes (e.g., Keck, VLT, Gemini, SALT, ATCA).

我们提议利用帕克斯天文台（Parkes）开展36小时观测，以延续成功的“更深、更广、更快”（Deeper, Wider, Faster，DWF）项目——该项目旨在探测快速暂现源与快速射电暴（fast radio burst，FRB）的对应体，并助力揭示其本质。DWF项目协调全球80余家天文台，覆盖从射电到伽马射线的全波长范围，以探测并跟进FRB及其他难以捕捉的快速暂现源（持续时间从毫秒至小时不等）。关键在于，我们协调所有波长下的同步深度、高时间分辨率、宽视场观测，与帕克斯天文台同时观测同一区域，从而能够在射电探测前、期间及之后实现多波长探测。目前，这些时间尺度上几乎没有达到显著深度的多波长观测，导致该参数空间尚未得到充分探索。DWF项目协调主要设施与帕克斯天文台协同观测，例如南极望远镜（South Pole Telescope，毫米/亚毫米波段）、GROND（红外波段）、CTIO暗能量相机（光学波段）、Astrosat（紫外/X射线波段）、HXMT（X射线波段）、HESS（伽马射线波段）及皮埃尔·奥格天文台（Pierre Auger，高能波段）。我们在所有波长上进行实时数据处理与暂现源识别，进而触发深度快速响应（数分钟内）后续项目——利用世界最大望远镜（如凯克望远镜、甚大望远镜、双子座望远镜、南非大望远镜、澳大利亚望远镜致密阵列）开展深度光谱学与成像观测。
