Spinflation
Damien A. Easson, Ruth Gregory, David F. Mota +2
We study the cosmological implications of including angular motion in the DBI brane inflation scenario. The non-canonical kinetic terms of the Dirac-Born-Infeld action give an inte…
A New Perspective on DGP Gravity
Ruth Gregory, Nemanja Kaloper, Robert C. Myers +1
We examine brane induced gravity on codimension-1 branes, a.k.a DGP gravity, as a theory of five-dimensional gravity containing a certain class four-dimensional branes. From this p…
Stealth Acceleration and Modified Gravity
Christos Charmousis, Ruth Gregory, Antonio Padilla
We show how to construct consistent braneworld models which exhibit late time acceleration. Unlike self-acceleration, which has a de Sitter vacuum state, our models have the standa…
Cycling in the Throat
Damien Easson, Ruth Gregory, Gianmassimo Tasinato +1
We analyse the dynamics of a probe D3-(anti-)brane propagating in a warped string compactification, making use of the Dirac-Born-Infeld action approximation. We also examine the ti…
