Parkes observations for project PX600 semester 2020APRS_139

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）项目射电波段观测的核心目标。作为天空中单一方向恒星数量最多的区域，银心被广泛认为可能存在先进文明，同时也是银河系内能量最高的区域。本项目计划使用帕克斯射电望远镜开展BL-GC巡天观测，总观测时长约350小时，将依托新安装的超宽带接收机（ultra-wideband receiver），覆盖700 MHz至4 GHz的频率范围。我们团队已结合标准工具与定制化工具搭建了灵活的软件栈，用于在观测数据中搜寻目标信号。本次搜寻将同时针对简单窄带信号与复杂调制信号，以寻找地外智慧生命（extraterrestrial intelligence, ETI）存在的迹象。作为辅助科学研究内容，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也将公开共享，以惠及更广泛的脉冲星研究社群。
