Barriola Vilenkin gravitational monopole: an exact solution. — •Piero Nicolini1, Marco Knipfer2, Sven Köppel1, and Jonas Mureika31Goethe Universität, Frankfurt — 2University of Alabama, Tuscaloosa — 3Loyola Marymount University, Los Angeles

After briefly recalling the properties of the Barriola-Vilenkin metric, we will present a new exact monopole solution in five dimensional nonlocal gravity. This object turns out to be the end point of the black hole evaporation. Interestingly for smaller masses, the spacetime admits a ``naked monopole'' rather than a generic naked singularity. The solution is discussed against current proposals for dark matter component candidates.
