Abstract
This paper evaluates the prospects of detecting double neutron stars (DNSs) in the Galactic disk using future space-borne gravitational wave (GW) detectors and subsequent radio follow-up observations. The authors simulate a Galactic DNS population, predicting the number of detectable DNSs by TianQin (TQ), LISA, and a combined TQ+LISA network. They then model radio pulse emission from potential pulsars within these DNSs, forecasting the number detectable by various radio telescopes (Parkes, FAST, SKA1, and SKA). The study also estimates the parameter estimation accuracy for detectable DNSs and the timing accuracy of the detectable pulsars.
