标题： Method to search for inspiraling planetary-mass ultra-compact binaries using the generalized frequency-Hough transform in LIGO O3a data

摘要： 来自亚太阳质量原初黑洞的引力波可能能够在LIGO、Virgo和KAGRA的数据中被探测到。 在这里，我们将一种最初设计用于寻找快速减速旋转的中子星的方法——广义频率-霍ough变换，应用于使用高级LIGO第三次观测运行前半部分的数据来搜寻行星质量的原初黑洞。 在这篇与arXiv:2402.19468相关的配套论文中，我们在其中展示了我们搜寻的主要结果，我们深入探讨了搜寻方法的细节、我们在探索参数空间方面所做的选择、我们用来确认或拒绝搜寻返回的可能候选者的后续程序，以及我们生成上置信限的解析程序与通过注入获得的结果的比较。 显示英文摘要

摘要： Gravitational waves from sub-solar mass primordial black holes could be detected in LIGO, Virgo and KAGRA data. Here, we apply a method originally designed to look for rapidly spinning-down neutron stars, the generalized frequency-Hough transform, to search for planetary-mass primordial black holes using data from the first half of the third observing run of advanced LIGO. In this companion paper to arXiv:2402.19468, in which the main results of our search are presented, we delve into the details of the search methodology, the choices we have made regarding the parameter space to explore, the follow-up procedure we use to confirm or reject possible candidates returned in our search, and a comparison of our analytic procedure of generating upper limits to those obtained through injections.
