Regular collision of dilatonic inflating branes
Emily Leeper, Kazuya Koyama, Roy Maartens
We demonstrate that a two brane system with a bulk scalar field driving power-law inflation on the branes has an instability in the radion. We solve for the resulting trajectory of…

Asymmetric radiating brane-world
Laszlo Gergely, Emily Leeper, Roy Maartens
At high energies on a cosmological brane of Randall-Sundrum type, particle interactions can produce gravitons that are emitted into the bulk and that can feed a bulk black hole. We…

Dynamics of radiating braneworlds
Emily Leeper, Roy Maartens, Carlos Sopuerta
If the observable universe is a braneworld of Randall-Sundrum type, then particle interactions at high energies will produce 5-dimensional gravitons that escape into the bulk. As a…
