Parkes observations for project PX600 semester 2020APRS_38

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。作为全天任意观测方向中恒星数量最多的天区，银心常被视作可能存在先进文明的候选区域，同时也是银河系内能量最为剧烈的区域。我们计划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。本次观测将覆盖700 MHz至4 GHz的频率范围，并将启用新安装的超宽带接收机（ultra-wideband receiver）。本团队已整合标准工具与定制化开发工具，搭建了灵活的软件栈以对观测数据开展目标信号搜索。我们将通过搜索简单窄带信号与复杂调制信号两类信号，来寻找地外智慧生命（extraterrestrial intelligence, ETI）的踪迹。此外作为附属科学研究内容，我们还将搜寻加速运动的脉冲星——这类脉冲星极有可能环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，以惠及更广泛的脉冲星研究社区。
