Dense DM clumps seeded by cosmic string loops and DM annihilation
dark matter cosmic string cosmology
2011/10/9
The annihilation of the dark matter in clumps around cosmic string loops is studied. These clumps form at the radiation dominated stage and may have densities \gg\rho_{eq}. We conclude that 100 GeV ne...

Topological Casimir effect compactified cosmic string spacetime
2011/10/18
We investigate the Wightman function, the vacuum expectation values of the field squared and the energy-momentum tensor for a massive scalar field with general curvature coupling in the generalized co...
