Parkes observations for project PX600 semester 2020APRS_55

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

银河中心（Galactic Center, GC）是“突破聆听”（Breakthrough Listen, BL）项目射电观测分支的核心目标。作为天球上任意给定方向内恒星总数最多的天区，银河中心被学界广泛视作可能存在高等外星文明的区域，同时也是银河系内能量活动最为剧烈的区域。本项目计划依托帕克斯射电望远镜（Parkes radio telescope）开展BL-GC巡天观测，总观测时长约350小时。观测将借助新部署的超宽带接收机（ultra-wideband receiver），覆盖700 MHz至4 GHz的频段范围。本团队已整合标准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。我们将通过两类信号的搜寻工作，探寻地外智慧生命（extraterrestrial intelligence, ETI）存在的踪迹：一类为简单窄带信号，另一类为复杂调制信号。除此之外，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。本项目产生的全部数据产品也将对外公开，以服务于更广泛的脉冲星研究社群。
