ASKAP Data Products for Project AS111 (ASKAP Pilot Survey for Gravitational Wave Counterparts): catalogues

This survey is designed to test and develop ASKAP’s capability to rapidly follow up on gravitational wave detections. When observatories such as LIGO issue event notifications, they will be assessed for the likelihood of a radio counterpart and a target of opportunity event triggered if the chance of detection is high (e.g. in the case of a double neutron star merger). Gravitational wave events often have a large angular uncertainty in their direction of origin, so ASKAP’s wide field of view makes it extremely effective at following up these events. Data processing strategies are similar to those of the VAST survey.

本巡天项目旨在测试并开发澳大利亚平方千米阵列（ASKAP）对引力波（gravitational wave）探测结果开展快速后续观测的能力。当激光干涉引力波天文台（LIGO）等观测设施发布引力波事件通知时，将评估该事件存在射电对应体（radio counterpart）的概率；若探测可信度较高（例如双中子星并合（double neutron star merger）事件），则触发机会目标（target of opportunity）观测任务。引力波事件的起源方向通常存在较大的角位置不确定性，因此ASKAP的宽视场特性使其在这类事件的后续观测中极具效率。其数据处理策略与VAST巡天（VAST survey）的策略基本一致。
