Kinks, extra dimensions, and gravitational waves
Eimear O'Callaghan, Ruth Gregory
We investigate in detail the gravitational wave signal from kinks on cosmic (super)strings, including the kinematical effects from the internal extra dimensions. We find that the s…
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…
The Cosmology of Asymmetric Brane Modified Gravity
Eimear O'Callaghan, Ruth Gregory, Alkistis Pourtsidou
We consider the asymmetric branes model of modified gravity, which can produce late time acceleration of the universe and compare the cosmology of this model to the standard CDM…
