Number of detectable events per continuous year of GW network operation.

LVC run Radio configuration GW events Joint events Fraction of detectable events

Instrument s (μJy) NGW Njoint (assuming fiducial model)
O3 VLA 15 31.4%
Design VLA 15 19.8%
Design SKA1 3 34.7%
Design SKA2/ngVLA 0.3 62.5%


The expected rate of total GW events is taken from Abbott et al. (2018) and values for joint events are derived using our fiducial population model. The uncertainties here are due to the uncertainty regarding the merger rate in the local Universe derived from GW observations of the LVC O1 and O2 runs. The additional uncertainties related to the population model are discussed in Sect. 4.2.
