Parkes observations for project PX600 semester 2020APRS_125

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）项目射电波段的核心观测目标。作为天空中任意给定天区方向内恒星数量最多的区域，银河中心被广泛认为是可能存在高等文明的场所，同时也是银河系中能量活动最剧烈的区域。本项目计划使用帕克斯（Parkes）射电望远镜开展为期约350小时的BL-GC巡天观测，将覆盖700 MHz至4 GHz的频段范围，并使用新安装的超宽带接收机。研究团队已结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。我们将通过搜寻两类信号来寻找地外智慧文明（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。除此之外，作为本项目的辅助科学研究方向，我们还将搜寻加速脉冲星——这类天体大概率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向公众开放，以服务于更广泛的脉冲星研究社群。
