Abstract: Coalescing compact binaries of neutron stars and/or black holes are considered as one of the most promising sources for Earth based gravitational wave detectors. The LIGO-Virgo joint collaboration's Compact Binary Coalescence (CBC) group is searching for gravitational waves emitted by these astrophysical systems by matched filtering the data against theoretically modeled template waveforms. A variety of waveform template families are employed depending on the mass range probed by the search and the stage of the inspiral phase targeted: restricted post-Newtonian for systems having total mass less than $35 \msun$, numerical relativity inspired complete inspiral-merger-ringdown waveforms for more massive systems up to $100\msun$ and ringdown templates for modeling perturbed black holes up to $500\msun$. We give a status update on CBC group's current efforts and upcoming plans in detecting signatures of astrophysical gravitational waves.
