Chirping gravitational wave signals from compact binary Coalescence were detected for the first time during LIGO/Virgo O1 and O2 observing runs. The majority of the events reported thus far came from binary systems of fairly heavy stellar mass black holes located at cosmological distances.

In addition, one spectacular binary neutron star merger event from just 40 Mpc away was detected in synergy with detailed electromagnetic counterparts. The O3 observing run is ongoing with the two LIGO detectors and the Virgo detector in simultaneous operation, and has reportedly increased the detected number of compact binary sources by great amount.

I will summarize the present status of compact binary sources detected through gravitational waves and their apparent population properties. In addition to events reported from LIGO/Virgo analysis, I will summarize existing efforts by independent groups to analyze the publicly released O1/O2 strain data in search of compact binary coalescence events. In particular, I will present work done by the IAS group, as a result of which we managed to decrease the detection threshold and uncovered many additional binary black hole merger events.
