Parkes observations for project PX600 semester 2020APRS_77

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

银河系中心（Galactic Center，GC）是突破聆听（Breakthrough Listen，BL）项目射电部分的关键目标。由于在天空任一方向上拥有最密集的恒星分布，GC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调查，观测时长约350小时。借助新安装的超宽带接收机，观测频率范围将覆盖700 MHz至4 GHz。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，用于搜索数据中的目标信号。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——这类脉冲星可能围绕银河系中心的超大质量黑洞运行。本项目产生的数据产品也将公开，以供更广泛的脉冲星研究社区使用。
