| contents | The existence or absence of gravitational radiation escaping from the spacetime at $\mathscr{J}$ is characterized in the presence of a cosmological constant $Λ$ of any sign. To that end, the properties of the asymptotic super-momentum are used. When $Λ=0$, the characterization is equivalent to that based on the News tensor. For $Λ\neq 0$, it provides the first reliable definition of existence of radiation at $\mathscr{J}$, and it gives fully satisfactory results in known exact solutions. |
