Parkes observations for project PX600 semester 2020APRS_150

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目标。作为天球上单一方向内恒星数量最多的区域，银心被广泛认为是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。本团队计划利用帕克斯射电望远镜（Parkes radio telescope）开展总时长约350小时的BL-GC巡天观测。观测将覆盖700 MHz至4 GHz的频段范围，并将启用新安装的超宽带接收机。我们的团队已结合标准工具与定制化工具搭建了一套灵活的软件栈，用于在观测数据中搜寻目标信号。我们将通过搜寻两类信号来寻找地外智慧生命（extraterrestrial intelligence, ETI）：一类是简单的窄带信号，另一类则是复杂的调制信号。除此以外，作为附属科学研究内容，我们还将搜寻可能环绕银河系中心超大质量黑洞运行的加速脉冲星。本项目产生的所有数据产品都将对外公开，以服务于更广泛的脉冲星研究社区。
