Parkes observations for project PX600 semester 2020APRS_99

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天区。作为天空中任一方向上恒星数量最多的天区，银心被广泛认为是可能蕴藏先进文明的区域，同时也是银河系中能量最为活跃的区域。我们计划使用帕克射电望远镜（Parkes radio telescope）开展为期约350小时的BL-GC巡天观测，将依托新安装的超宽带接收机覆盖700兆赫兹至4吉赫兹的频段范围。我们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。本次巡天将通过搜寻简单窄带信号与复杂调制信号两种类型，来寻找地外智慧文明（extraterrestrial intelligence, ETI）的相关信号。除此之外，作为本项目的附属科学研究内容，我们还将搜寻可能绕银河系中心超大质量黑洞运行的加速脉冲星。本项目产生的各类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。
