Parkes observations for project PX600 semester 2020APRS_48

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。作为全天中恒星数量最多的天区，银心被广泛认为存在先进文明，同时也是银河系内能量最为活跃的区域。本项目计划依托帕克斯射电望远镜开展BL-GC巡天观测，总时长约350小时。观测将覆盖700 MHz至4 GHz的频段范围，并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灵活的软件栈，用于对观测数据开展目标信号搜索。我们将通过搜寻两类信号来寻找地外智慧生命（extraterrestrial intelligence，ETI）的踪迹：一类为简单窄带信号，另一类为复杂调制信号。此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。本项目产生的全部数据产品也将对外公开，以惠及更广泛的脉冲星研究社群。
