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…
New bounds for the area of MOTS and generalized ultra-massive spacetimes
José M. M. Senovilla
Bounds for the area of general closed marginally trapped surfaces (MTSs) are presented. They do not require any stability condition, and are determined by a constant that depends o…
Junction Conditions for General Gravitational Theories
José M. M. Senovilla
The junction conditions for general theories of gravity based on actions that depend on arbitrary functions of the curvature scalar invariants (including differential invariants) a…
On the regularity of deformed extremal horizons
Francesco Di Filippo, Shinji Mukohyama, José M. M. Senovilla
It has recently been argued that extremal black holes can act as amplifiers of new physics, due to horizon instabilities that enhance the effects of ultraviolet corrections. In thi…
Gravitational waves in Cubic Metric-Affine Gravity
Sebastian Bahamonde, Jorge Gigante Valcarcel, José M. M. Senovilla
We derive new exact gravitational wave solutions with dynamical torsion and nonmetricity tensors in the framework of cubic Metric-Affine Gravity (MAG). For this purpose, we conside…
