Parkes observations for project PX600 semester 2020APRS_129

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。作为天空中给定天区范围内恒星数量最多的区域，银心被广泛认为可能存在先进文明，同时也是银河系中能量活动最为剧烈的区域。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，观测将覆盖700 MHz至4 GHz的频段范围，并采用新安装的超宽带接收机。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，用于从观测数据中搜寻目标信号。我们将通过搜寻两类信号来寻找地外智慧文明（extraterrestrial intelligence, ETI）存在的迹象：一类是简单的窄带信号，另一类是复杂的调制信号。此外，作为本项目的附属科学研究内容，我们还将搜寻受银心超大质量黑洞引力束缚的加速脉冲星。本项目产生的所有数据产品也将对外公开，以供更广泛的脉冲星研究社群使用。
