Parkes observations for project PX600 semester 2020APRS_47

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

银河系中心（Galactic Center, GC）是「突破聆听」（Breakthrough Listen, BL）项目射电波段的核心观测目标。作为天空中任一方向上恒星数量最多的天区，银河系中心被广泛认为是可能存在先进文明的区域，同时也是银河系内能量活动最剧烈的区域。本项目拟使用帕克斯（Parkes）射电望远镜开展为期约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，并使用新近安装的超宽带接收机完成数据采集。本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，用于从观测数据中检索目标信号。我们将通过搜寻两类信号来探寻地外智慧生命（extraterrestrial intelligence, ETI）的存在迹象：一类是简单的窄带信号，另一类是复杂调制信号。此外，作为本项目的辅助科学研究内容，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面向公众开放，以惠及更广泛的脉冲星研究社群。
