Time dependent black holes and scalar hair
Sarah Chadburn, Ruth Gregory
We show how to correctly account for scalar accretion onto black holes in scalar field models of dark energy by a consistent expansion in terms of a slow roll parameter. We find an…
Cosmic superstring trajectories in warped compactifications
Anastasios Avgoustidis, Sarah Chadburn, Ruth Gregory
We explore the generic motion of cosmic (super)strings when the internal compact dimensions are warped, using the Klebanov-Strassler solution as a prototypical throat geometry. We…
The effect of extra dimensions on gravity wave bursts from cosmic string cusps
Eimear O'Callaghan, Sarah Chadburn, Ghazal Geshnizjani +2
We explore the kinematical effect of having extra dimensions on the gravity wave emission from cosmic strings. Additional dimensions both round off cusps, and reduce the probabilit…
Effect of extra dimensions on gravitational waves from cosmic strings
Eimear O'Callaghan, Sarah Chadburn, Ghazal Geshnizjani +2
We show how taking into account the kinematical effect of extra dimensions can have a significant impact on the gravity wave emission from cosmic strings. Additional dimensions bot…
