Abstract        :

In this talk, I will discuss the possibilities of detecting
gravitational waves (GW) from hyperbolic encounters with the current and
future ground based interferometric detectors. Given that the globular
clusters are most favorable to host these events, we consider scattering
events inside these dense clusters, and obtain event rates for observing
such encounters. By incorporating the localized effects appearing inside a
cluster, ignoring relativistic effects and using realistic cluster model,
we argue that our estimations are on conservative side, while the actual
detection rates can significantly surpass these average rates. I will
discuss these results in detail, pointing out its implication in the GW
astronomy and understanding cluster's properties
