Asymptotic Gravitational Radiation of Photon Rockets with : Point, String, and Sheet Sources

Francisco Fernández-Álvarez, José M. M. Senovilla

We study the existence of gravitational radiation at infinity for pure-radiation Robinson-Trautman metrics with one spacelike Killing vector and a cosmological constant of arbi…

Study of gravitational radiation at for the general type-D Einstein-Maxwell solution with cosmological constant

Francisco Fernández-Álvarez, José M. M. Senovilla

We characterize the gravitational radiation present in the general Plebański-Demiański type~D solution with cosmological constant of any sign. We show that radiation escapes to…

The peeling theorem with arbitrary cosmological constant

Francisco Fernández-Álvarez, José M. M. Senovilla

A method for deriving the asymptotic behaviour of any physical field is presented. This leads to a geometrically meaningful derivation of the peeling properties for arbitrary value…

Asymptotic Structure with a positive cosmological constant

Francisco Fernández-Álvarez, José M. M. Senovilla

This is the second of two papers that study the asymptotic structure of space-times with a non-negative cosmological constant . This paper deals with the case . Our approac…

Asymptotic Structure with vanishing cosmological constant

Francisco Fernández-Álvarez, José M. M. Senovilla

This is the first of two papers devoted to the asymptotic structure of space-time in the presence of a non-negative cosmological constant . This first paper is concerned with th…

Gravitational radiation condition at infinity with a positive cosmological constant

Francisco Fernández-Álvarez, José M. M. Senovilla

Gravitational waves have been directly detected and astronomical observations indicate that our Universe has a positive cosmological constant . Nevertheless, a theoretical gauge…
