Parkes observations for project PX600 semester 2020APRS_01

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。作为天空中任意方向上恒星数量最多的区域，银心被广泛认为是可能蕴藏高等智慧文明的场所，同时也是银河系内能量最为活跃的区域。我们计划使用帕克斯（Parkes）射电望远镜开展BL-GC巡天项目，总观测时长约350小时。本次观测将采用新安装的超宽带接收机（ultra-wideband receiver），覆盖700 MHz至4 GHz的频率范围。我们的团队已整合标准工具与定制化工具，搭建了灵活的软件栈以开展目标信号搜索工作。我们将通过搜寻两类信号来寻找地外智慧生命（extraterrestrial intelligence, ETI）的踪迹：一类为简单的窄带信号，另一类则为复杂的调制信号。除此之外，作为本项目的辅助科学研究内容，我们还将搜寻加速运动的脉冲星——这些脉冲星很可能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都将向公众开放，以惠及更广泛的脉冲星研究社区。
