Bounding the mass of graviton in a dynamic regime with binary pulsars
Bounding the mass of graviton in a dynamic regime with binary pulsars
In Einstein's general relativity, gravity is mediated by a massless spin-2 metric field, and its extension to include a mass for the graviton has profound implications for gravitation and cosmology. In 2002, Finn and Sutton [1] used the gravitational-wave (GW) backreaction in binary pulsars, and provided the first bound on …
