Parkes observations for project PX600 semester 2020APRS_27

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）计划射电部分的核心目标。由于在天空任意方向上拥有最多的恒星数量，银心被广泛认为是可能存在高级文明的区域，同时也是银河系中能量最活跃的区域。我们计划利用帕克斯射电望远镜开展BL-GC巡天观测，总时长约350小时。观测将覆盖700 MHz至4 GHz的频率范围，使用新安装的超宽带接收机。我们团队已利用标准工具与定制工具构建了一套灵活的软件栈，用于从数据中搜索感兴趣的信号。我们将通过搜索简单窄带信号与复杂调制信号，寻找来自地外智能（Extraterrestrial Intelligence, ETI）的信号。此外，作为辅助科学目标，我们还将搜索加速脉冲星——这类脉冲星可能绕银河系中心的超大质量黑洞运行。本计划产生的数据产品也将公开，以供更广泛的脉冲星研究社群使用。
