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.

银河系中心（Galactic Centre）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（pulsars）、分子谱线（molecular lines）、脉泽源（masers）以及暂现源（transient sources）。若能在银河系中心黑洞（central black hole）周围发现脉冲星，或是观测到全新的谱特征（其可能源自暗物质（dark matter）），都将具有重大科学研究价值。本研究提议对银河系中心周边1度范围的天区开展高灵敏度巡天观测，同步记录多组数据流，以实现对暂现天体与谱线（spectral lines）的搜寻工作。本次巡天的观测策略将基于我们团队近期针对巴德窗（Baade's Window）开展的伴随式巡天（commensal survey）经验。
