论文摘要
尚未检测到来自旋转变形的中子星的连续重力波，并且是未来检测最有希望的信号之一。在二进制系统中，来自未知中子星星的连续重力波的全天搜索是最具挑战性的搜索类型。因此，对于这些来源，很少有搜索算法和实现存在，到目前为止，仅执行了少数此类搜索。在本文中，我们提出了一种新的全套二进制搜索方法，即二进制二进制搜索方法，即二进制二进制搜索方法，该方法扩展并改进了较早的binaryskyhough方法，并且是最近搜索的基础（Covas等人[1]）。我们将灵敏度和计算成本与以前的方法进行比较，表明它既更敏感又具有计算效率，从而可以进行更广泛，更敏感的搜索。
Continuous gravitational waves from spinning deformed neutron stars have not been detected yet, and are one of the most promising signals for future detection. All-sky searches for continuous gravitational waves from unknown neutron stars in binary systems are the most computationally challenging search type. Consequently, very few search algorithms and implementations exist for these sources, and only a handful of such searches have been performed so far. In this paper, we present a new all-sky binary search method, BinarySkyHou$\mathcal{F}$, which extends and improves upon the earlier BinarySkyHough method, and which was the basis for a recent search (Covas et al. [1]). We compare the sensitivity and computational cost to previous methods, showing that it is both more sensitive and computationally efficient, which allows for broader and more sensitive searches.
