             abstract = "The observation of GW170817 binary neutron star (BNS) merger event 
                         has imposed strong bounds on the speed of gravitational waves 
                         (GWs) locally, inferring that the speed of GWs propagation is 
                         equal to the speed of light. Current GW detectors in operation 
                         will not be able to observe BNS merger to long cosmological 
                         distance, where possible cosmological corrections on the cosmic 
                         expansion history are expected to play an important role, 
                         specially for investigating possible deviations from general 
                         relativity. Future GW detectors designer projects will be able to 
                         detect many coalescences of BNS at high z, such as the third 
                         generation of the ground GW detector called Einstein Telescope 
                         (ET) and the space-based detector deci-hertz interferometer 
                         gravitational wave observatory (DECIGO). In this paper, we relax 
                         the condition c(T)/c = 1 to investigate modified GW propagation 
                         where the speed of GWs propagation is not necessarily equal to the 
                         speed of light. Also, we consider the possibility for the running 
                         of the Planck mass corrections on modified GW propagation. We 
                         parametrize both corrections in terms of an effective GW 
                         luminosity distance and we perform a forecast analysis using 
                         standard siren events from BNS mergers, within the sensitivity 
                         predicted for the ET and DECIGO. We find at high z very strong 
                         forecast bounds on the running of the Planck mass, namely O 
                         (10(-1)) and O(10(-2)) from ET and DECIGO, respectively. Possible 
                         anomalies on GW propagation are bound to vertical bar c(T)/c - 1 
                         vertical bar <= 10(-2) (10(-2)) from ET (DECIGO), respectively. We 
                         finally discuss the consequences of our results on modified 
                         gravity phenomenology.",
