Abstract: In this note we construct families of asymptotically flat, smooth, horizonless solutions with a large number of non-trivial two-cycles (bubbles) of = 1 five-dimensional supergravity with an arbitrary number of vector multiplets, which may or may not have the charges of a macroscopic black hole and which contain the known bubbling solutions as a sub-family. We do this by lifting various multi-center BPS states of type IIA compactified on Calabi-Yau three-folds and taking the decompactification (M-theory) limit. We also analyse various properties of these solutions, including the conserved charges, the shape, especially the (absence of) throat and closed timelike curves, and relate them to the various properties of the four-dimensional BPS states. We finish by briefly commenting on their degeneracies and their possible relations to the fuzzball proposal of Mathur et al.

Split states, entropy enigmas, holes and halos
Frederik Denef,Gregory W. Moore +1 more
TL;DR: In this paper, a factorization formula for BPS indices using attractor flow trees associated to multicentered black hole bound states was developed, which enables us to study background dependence of the BPS spectrum, to compute explicitly exact indices of various nontrivial D-brane systems, and to clarify the subtle relation of Donaldson-Thomas invariants to BPs indices of stable D6-D2-D0 states, realized in supergravity as hole halos.

The fuzzball proposal for black holes
Kostas Skenderis,Marika Taylor +1 more
TL;DR: The fuzzball proposal as mentioned in this paper states that associated with a black hole of entropy S, there are exp S horizon-free non-singular solutions that asymptotically look like the black hole but generically differ from the original black hole up to the horizon scale.

The geometry of N = 2 Maxwell-Einstein supergravity and Jordan algebras
TL;DR: In this paper, the general coupling of nN = 2 Maxwell super-multiplets to N = 2 supergravity in five spacetime dimensions was constructed. But the authors only considered the case that the scalar field manifold is symmetric.

TL;DR: In this paper, it was shown that near-extremal black holes are obtained by exciting the Ramond sector of the D1-D5 CFT, where the ground state is highly degenerate.
