Parkes observations for project PX600 semester 2020APRS_33

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）项目射电频段的核心观测目标。作为天空中任一给定方向内恒星数量最多的天区，银心被广泛认为是可能存在先进文明的区域，同时也是银河系中能量活动最剧烈的区域。本项目拟利用帕克斯射电望远镜开展BL-GC巡天观测，总观测时长约350小时。我们将使用新安装的超宽带接收机，覆盖700兆赫兹至4吉赫兹的观测频段。本团队已结合标准工具与定制化工具搭建了灵活的软件栈，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生命（extraterrestrial intelligence, ETI）发出的信号：一类是简单的窄带信号，另一类是复杂调制信号。与此同时，作为本项目的附属科学研究，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。本项目产生的所有数据产品也将面向全球脉冲星研究共同体公开共享，以促进相关领域的学术协作。
