Gravitational wave observatories may be able to detect hyperbolic encounters of black holes

Gravitational wave (GW) astronomy promises to observe different kinds of astrophysical sources. Here, we explore the possibility of detection of GWs from hyperbolic interactions of compact stars with ground-based interferometric detectors. It is believed that a bound compact cluster, such as a globular cluster, can be a primary environment for these interactions. We estimate the detection rates fo...
