标题： Flea on the elephant: Tidal Love numbers in subsolar primordial black hole searches

摘要： 探测黑洞双星合并中的亚太阳质量天体被认为是原始黑洞的标志性特征。 它们被认为消失的潮汐爱德华数通常被认为有助于将它们与其它亚太阳质量和更易变形的致密天体区分开来，比如中子星。 我们表明，在系统存在即使是微小扰动的情况下，原始黑洞会产生一个大且可检测的爱德华数，这可能危及其发现。 然而，这种小扰动并不紧密束缚，因此会在合并之前被破坏。 我们证明了它们会在引力波信号中留下一个特征签名，可以通过当前和未来的引力波探测器观测到。 因此，它们仍可能暗示合并中黑洞的原始性质。 最后，我们演示了在匹配滤波器搜索亚太阳引力波事件时忽略可能的环境效应会导致探测器灵敏度降低。 显示英文摘要

摘要： Detecting subsolar objects in black hole binary mergers is considered a smoking gun signature of primordial black holes. Their supposedly vanishing tidal Love number is generically thought to help distinguish them from other subsolar and more deformable compact objects, such as neutron stars. We show that a large and detectable Love number of primordial black holes can be generated in the presence of even small disturbances of the system, thus potentially jeopardizing their discovery. However, such small perturbations are not tightly bound and are therefore disrupted before the mergers. We show that they leave a characteristic signature in the gravitational waveform that could be observed with current and future gravitational wave detectors. Thus, they may still hint towards the primordial nature of the black holes in the merger. Finally, we demonstrate that disregarding possible environmental effects in the matched-filter search for subsolar gravitational wave events can lead to a decreased sensitivity in the detectors.
