Parkes observations for project P1066 semester 2021APRS_11

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).

我们提议开展36小时的帕克斯望远镜（Parkes）观测，以延续我们已取得成功的“更深、更广、更快”（Deeper, Wider, Faster，以下简称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，并助力阐明其本质。DWF项目协调了全球80余座天文台开展全波段观测，覆盖从射电到伽马射线的所有频段，用于探测并跟进快速射电暴及其他难以捉摸的、持续时长介于毫秒至小时量级的快速暂现源。至关重要的是，本项目将协调开展同步的深场、快速轮巡宽视场观测，与帕克斯望远镜同步对准同一天区，从而能够在射电探测前、探测期间及探测后完成多波段探测。此前在这类时间尺度上，几乎未开展过任何具备显著深度的多波段观测，使得该参数空间尚未得到充分探索。DWF项目协调了可与帕克斯望远镜协同观测的大型科研设施，包括南极望远镜（South Pole Telescope，毫米波/亚毫米波波段）、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）以及皮埃尔·奥杰天文台（Pierre Auger，高能频段）。本项目将开展全波段的实时数据处理与暂现源识别工作，可在探测到信号后数分钟内触发快速响应跟进项目，使用全球最大型望远镜（如凯克望远镜、甚大望远镜VLT、双子座望远镜、南非大望远镜SALT、澳大利亚紧凑阵列ATCA）开展深场光谱与成像观测。
