Parkes observations for project PX600 semester 2020APRS_91

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）项目射电观测的核心目标。作为天空中任意给定方向内恒星数量最多的天区，银心被广泛视作可能存在先进文明的区域，同时也是银河系内能量最为活跃的区域。本项目计划依托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。我们将采用新安装的超宽带接收机，覆盖700 MHz至4 GHz的频段范围。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。我们将同时搜寻简单窄带信号与复杂调制信号，以探寻地外智慧生命（extraterrestrial intelligence，ETI）发出的信号。此外，作为附带科学研究内容，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。本项目产生的所有数据产品也将对外公开，以惠及更广泛的脉冲星研究社群。
