One of the key challenges of real-time detection and parameter estimation of gravitational waves from compact binary mergers is the computational cost of conventional matched-filtering and Bayesian inference approaches.

With the larger BNS horizon distance in the Cosmic Explorer era, on-axis short gamma-ray bursts (SGRBs) and their afterglows (though accompanying only some of the GW-detected mergers) supplant kilonovae as the most promising counterparts for redshift identification.

We find that the tidal deformability and 90$\%$ credible interval is $\tilde{\Lambda}=310^{+679}_{-234}$ for a uniform component mass prior, $\tilde{\Lambda}=354^{+691}_{-245}$ for a component mass prior informed by radio observations of Galactic double neutron stars, and $\tilde{\Lambda}=334^{+669}_{-241}$ for a component mass prior informed by radio pulsars.
