Galileons and Naked Singularities

Thomas Curtright (UM), November 14

Spherically symmetric solutions of hypothetical scalar field "galileon" models will be discussed in the context of general relativity. There are two distinct phases of solutions arising from physically reasonable boundary conditions. Those in the "censored" phase exhibit horizons, as expected, while those in the "naked" phase have curvature singularities without horizons.
