Abstract: We describe and study families of BPS microstate geometries, namely, smooth, horizonless asymptotically-a t solutions to supergravity. We examine these solutions from the perspective of earlier attempts to nd solitonic solutions in gravity and show how the microstate geometries circumvent the earlier \No-Go" theorems. In particular, we re-analyse the Smarr formula and show how it must be modied in the presence of non-trivial second homology. This, combined with the supergravity Chern-Simons terms, allows the existence

Fractionated Branes and Black Hole Interiors
TL;DR: In this paper, a picture of the black hole interior was developed where spacetime caps off at an inner horizon, and the inter-horizon region is occupied by a Hagedorn gas of a very low tension state of fractionated branes.
Shadow of a charged black hole with scalar hair
TL;DR: In this paper , the authors studied the shadow of a charged black hole with scalar hair in terms of four kinds of observers, i.e., static observers, surrounding observers, freely falling observers, and escaping observers in four-dimensional spacetime.
Topological Stars and Black Holes
Ibrahima Bah,Pierre Heidmann +1 more
TL;DR: Smooth bubble spacetimes in five-dimensional Einstein-Maxwell theory that resemble four-dimensional magnetic black holes upon Kaluza-Klein reduction are studied and are described as topological stars since they have topological cycles supported by magnetic flux.

Black hole explosions
TL;DR: In this article, it was shown that any black hole will create and emit particles such as neutrinos or photons at just the rate that one would expect if the black hole was a body with a temperature of (κ/2π) (ħ/2k) ≈ 10−6 (M/M)K where κ is the surface gravity of the body.

Microscopic origin of the Bekenstein-Hawking entropy
Andrew Strominger,Cumrun Vafa +1 more
TL;DR: The Bekenstein-Hawking area entropy relation S BH = A 4 was derived for a class of five-dimensional extremal black holes in string theory by counting the degeneracy of BPS solition bound states.

Magnetic monopoles in unified gauge theories
TL;DR: In this article, it was shown that in all those gauge theories in which the electromagnetic group U(1) is taken to be a subgroup of a larger group with a compact covering group, like SU(2) or SU(3), genuine magnetic monopoles can be created as regular solutions of the field equations.

Foundations of the new field theory
Max Born,Leopold Infeld +1 more
TL;DR: The relation of matter and the electromagnetic field can be interpreted from two opposite standpoints as discussed by the authors : the unitarian viewpoint assumes only one physical entity (e.g., a single unitary entity) and the second viewpoint assumes that all particles of matter are considered as singularities of the field and mass is a derived notion expressed by field energy (electromagnetic mass).
Black holes in higher dimensional space-times
Robert C. Myers,Malcolm J. Perry +1 more
TL;DR: In this paper, a new family of solutions were found which describe spinning black holes in higher dimensional space-times, which are similar to the familiar Kerr and Schwarzschild metrics which are recovered for N = 3.
