Parkes observations for project P1066 semester 2024OCTS_04

We propose 24 hrs of Parkes observations to continue the Deeper, Wider, Faster (DWF) program to detect fast transients and fast radio burst (FRB) counterparts and help resolve their nature. DWF coordinates major observatories worldwide at all wavelengths, from radio to gamma-ray and particle detectors 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 and provide the only program to search for multiwavelength counterparts to single-burst FRBs. Little to no multi-wavelength observations to any significant depth have been done on these timescales, leaving this parameter space little explored.

我们提议开展24小时帕克斯射电望远镜(Parkes)观测任务，以延续“更深、更广、更快”（Deeper, Wider, Faster, DWF）项目的研究工作，旨在探测快速暂现源及快速射电暴(Fast Radio Burst, FRB)对应体，并助力阐明其物理本质。DWF项目协调全球范围内全波段（从射电到伽马射线）的主要观测台站与粒子探测器，对快速射电暴及其他难以捉摸的快速暂现源（持续时长为毫秒至数小时）开展探测与后续跟进观测。尤为关键的是，本项目将协调开展全波段同步的深场、高重访频次、大视场观测，与帕克斯射电望远镜同时对准同一天区，从而可在射电探测前、探测过程中及探测完成后实现多波段探测；本项目亦是目前唯一可针对单爆发快速射电暴搜寻多波段对应体的科研项目。目前在该类时间尺度上，尚无具备足够探测深度的多波段观测记录，因此该参数空间几乎未被系统探索。
