Magnetized Solutions in Minimal Gauged Supergravity

We present new black hole solutions in five-dimensional Einstein–Maxwell–Chern–Simons theory with a negative cosmological constant. They rotate with two equal-magnitude angular momenta and they are electrically charged. In addition they possess a non-vanishing magnetic potential at infinity, where they approach asymptotically a global AdS5 space-time. We investigate some of their properties, and we show that these black holes possess a regular extremal limit, and under some additional conditions, a regular solitonic limit as well.

The 6D Gauss–Bonnet Supergravity Invariant

We review the recent construction of the off-shell N=(1,0) supersymmetrization of the Gauss–Bonnet curvature squared combination in six dimensions.

Toward microstate counting beyond large N in localization and the dual one-loop quantum supergravity

The topologically twisted index for ABJM theory with gauge group U(N) k × U(N) -k has recently been shown, in the large-N limit, to reproduce the BekensteinHawking entropy of certain magnetically charged asymptotically AdS 4 black holes. We numerically study the index beyond the large-N limit and provide evidence that it contains a subleading logarithmic term of the form -1/2 log N. On the holographic side, this term naturally arises from a one-loop computation. However, we find that the contribution coming from the near horizon states does not reproduce the field theory answer. Lastly, we give some possible reasons for this apparent discrepancy.

The M-theory S-matrix from ABJM: beyond 11D supergravity

We show that by studying the flat spacetime limit of the Mellin amplitude associated with the four-point correlation function of scalar operators in the stress tensor multiplet of ABJM theory, one can produce the momentum expansion of the M-theory four-graviton S-matrix elements. Using CFT data previously obtained from the supersymmetric localization method, we carry out this procedure explicitly to the second nontrivial order in the momentum expansion, and recover precisely the known R 4 contribution to the scattering amplitude of super-gravitons in M-theory in eleven dimensions.

AdS 5 compactifications with punctures in massive IIA supergravity

We find AdS 5 solutions holographically dual to compactifications of six- dimensional N = (1, 0) supersymmetric field theories on Riemann surfaces with punctures. We simplify a previous analysis of supersymmetric AdS 5 IIA solutions, and with a suitable Ansatz we find explicit solutions organized in three classes, where an O8-D8 stack, D6-and D4-branes are simultaneously present, localized and partially localized. The D4-branes are smeared over the Riemann surface and this is interpreted as the presence of a uniform distribution of punctures. For the first class we identify the corresponding six-dimensional theory as an E-string theory coupled to a quiver gauge theory. The second class of solutions lacks D6-branes and its central charge scales as n 5/2 , suggesting a five-dimensional origin for the dual field theory. The last class has elements of the previous two.

Geodesic analysis and black hole shadows on a general non-extremal rotating black hole in five-dimensional gauged supergravity

In this work, motivated by the fact that higher dimensional theories predict the existence of black holes which differ from their four dimensional counterpart, we analyse the geodesics and black hole shadow cast by a general non-extremal five dimensional black hole. The system under consideration corresponds to the Chong–Cvetič–Lü–Pope (Chong et al., 2005), which has the Myers–Perry black hole as a limit.
