Very recently, LIGO Scientific collaboration has made the first direct detection of gravitational waves (GWs) emitted from two coalescing stellar mass black holes (BHs). This detection, with the advanced GW detectors, has given hope to detect more and more coalescing binaries, helping us to reveal their interesting properties. There exist certain equilibrium configurations in spinning and precessing binaries in which spins of the BHs and orbital angular momentum of the binary remain in a plane (the resonant plane) during their evolution. The spin-orbit resonances have important astrophysical implications as the evolution and subsequent coalescence of super-massive BH binaries in this configuration leads to low recoil velocities of merger remnants. Hence, the final BHs will be retained in their host galaxies that are formed from the merger of smaller galaxies. In this talk, we will show the results of our investigation whether the existing detection pipelines are able to detect such GW sources. We'll also discuss our efforts to understand the physical nature of these special types of binaries.
