“…In particular bubbling solutions for black holes and black rings, to be described below, were developed in [95,96,97,98,99,100,101,102,103,104]. Four charge solutions in four dimensions have been discussed in [105,106]. Non-supersymmetric solutions were found and their properties explored in [107,108,109].…”

The fuzzball proposal 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 black hole up to the horizon scale. These solutions, the fuzzballs, are considered to be the black hole microstates while the original black hole represents the average description of the system. The purpose of this report is to review current evidence for the fuzzball proposal, emphasizing the use of AdS/CFT methods in developing and testing the proposal. In particular, we discuss the status of the proposal for 2 and 3 charge black holes in the D1-D5 system, presenting new derivations and streamlining the discussion of their properties. Results to date support the fuzzball proposal but further progress is likely to require going beyond the supergravity approximation and sharpening the definition of a "stringy fuzzball". We outline how the fuzzball proposal could resolve longstanding issues in black hole physics, such as Hawking radiation and information loss.Our emphasis throughout is on connecting different developments and identifying open problems and directions for future research.

“…The standard, bubbled microstate geometries [5,35,[37][38][39]42] allow singularities at points in the R 3 defined by y. Indeed, near such a singular point, P , one has V ∼ qp rp while one also requires that the Z I are finite as r p → 0 and the bubble equations require that µ(r p ) = 0.…”

We analyze the BPS solutions of minimal supergravity coupled to an anti-selfdual tensor multiplet in six dimensions and find solutions that fluctuate non-trivially as a function of two variables. We consider families of solutions coming from KKM monopoles fibered over Gibbons-Hawking metrics or, equivalently, non-trivial T 2 fibrations over an R 3 base. We find smooth microstate geometries that depend upon many functions of one variable, but each such function depends upon a different direction inside the T 2 so that the complete solution depends non-trivially upon the whole T 2 . We comment on the implications of our results for the construction of a general superstratum.

“…According to this proposal, a black hole quantum state is not well approximated by its classical geometry near its horizon, but is rather defined as a sum of microstates that are themselves well approximated by globally hyperbolic smooth geometries. While the search for the possible smooth geometries has met with some success in the case of extremal black holes, especially in the presence of supersymmetry [3][4][5][6][7][8][9][10][11], less progress has been made for the non-extremal black holes, for which only a handful of special solutions are known [12][13][14][15][16][17].…”

We define a new partially solvable system of equations that parametrises solutions to six-dimensional N = (1, 0) ungauged supergravity coupled to tensor multiplets. We obtain this system by applying a series of dualities on the known floating brane system, imposing that it allows for the JMaRT solution. We construct an explicit multi-centre solution generalising the JMaRT solution, with an arbitrary number of additional BPS centres on a line. We describe explicitly the embedding of the JMaRT solution in this system in five dimensions.
