BinarySkyHough：寻找双星系统中未知中子星连续引力波的新方法
BinarySkyHough: a new method to search for continuous gravitational waves from unknown neutron stars in binary systems
摘要：
双星系统中非轴对称、快速旋转的未知中子星可能会发出连续的引力波（接近单色的长时间信号），这些信号可以被LIGO和Virgo等地面探测器探测到。在本文中，我们提出了一个新的管道，称为$\textit{BinarySkyHough}$，可以进行全天搜索的中子星的二进制系统，利用图形处理单元的使用。我们给出了一个详细的解释，这个新的管道，我们提出了模拟，使我们能够估计新的管道，这是大约两倍的灵敏度与可比的计算成本的最佳主动管道的灵敏度。
英文摘要：
Non-axysymmetric, fast-spinning unknown neutron stars in binary systems may emit continuous gravitational waves (nearly-monochromatic long-duration signals) which can be detected by ground-based detectors like LIGO and Virgo. In this paper we present a new pipeline, called $\textit{BinarySkyHough}$, that can carry out all-sky searches for neutron stars in binary systems by exploiting the usage of graphics processing units. We give a detailed explanation of this new pipeline, and we present simulations which allow us to estimate the sensitivity of the new pipeline, which is approximately twice as sensitive as the best active pipeline with a comparable computational cost.
