Parkes observations for project PX600 semester 2020APRS_51

The Galactic Center (GC) is a key target for the radio component of Breakthrough Listen (BL) program. Offering the largest amount of stars in any given direction in the sky, the GC is widely cited as a location believed to harbour advanced civilizations, and it is also the most energetic region in the Milky Way. We aim to conduct BL-GC Survey with Parkes radio telescope for around 350 hours. We will cover the frequency range from 700 MHz to 4 GHz, utilizing the newly installed ultra-wideband receiver. Our team has already leveraged both standard and bespoke tools to construct a flexible software stack to search data for signals of interest. We will look for signals from extraterrestrial intelligence (ETI) by searching for both simple narrow-band signals and complex modulated signals. Along with that, as an ancillary science, we will also search for accelerated pulsars — likely orbiting a supermassive black hole at the centre of the Milky Way Galaxy. Data products produced during this program will also be publically available to engage larger pulsar community

银心（Galactic Center, GC）是“突破聆听”（Breakthrough Listen, BL）项目射电观测分支的核心观测目标。作为天空中特定方向上恒星数量最多的区域，银心被广泛视作可能孕育高等外星文明的场所，同时也是银河系内能量最为活跃的区域。本项目计划使用帕克斯射电望远镜（Parkes radio telescope）开展时长约350小时的BL-GC巡天观测。我们将借助新安装的超宽带接收机，覆盖700兆赫兹至4吉赫兹的观测频段。本团队已整合标准化工具与定制化开发工具，搭建了一套灵活的软件栈，用于从观测数据中检索目标信号。我们将通过检索两类信号来搜寻地外文明（extraterrestrial intelligence, ETI）发出的信号：一类是简单窄带信号，另一类是复杂调制信号。此外，作为本项目的附属科学研究内容，我们还将搜寻加速脉冲星——这类天体大概率环绕银河系中心的超大质量黑洞运行。本项目产生的所有数据产品也将对外公开，以供更广泛的脉冲星研究社群使用。
