Parkes observations for project P1167 semester 2022OCTS_03

The Galactic centre region has huge discovery potential. We know of pulsars, molecular lines, masers and transient sources all in that area. The discovery of a pulsar around the central black hole, or completely new spectral features (possibly from dark matter) would be of enormous scientific interest. We propose a sensitive survey of a 1 degree region around the Galactic centre in which we simultaneously record data streams that will allow us to search for transient objects and spectral lines. We will base our observing strategy from our recent, commensal, survey of Baade's window.

银河中心区域具备极高的科学发现潜力。目前我们已在该区域内观测到脉冲星（pulsar）、分子谱线（molecular lines）、脉泽源（masers）与暂现源（transient sources）等多种天体。若能在银心黑洞（central black hole）周围发现脉冲星，或是观测到全新的谱线特征（spectral features，其可能源自暗物质（dark matter）），都将具有极高的科学价值。我们提议对银河中心周边1度天区开展高灵敏度巡天（sensitive survey），同步采集数据流（data streams）以开展暂现天体与分子谱线的搜寻工作。本次观测策略将参考我们近期针对巴德窗（Baade's window）开展的伴随巡天（commensal survey）项目。
