“…The results in [9] show that the qualitative behaviour of the BHs with small |c m | resembles that of the unmagnetized CLP case. However, a different picture is found for large enough values of c m , with a monotonic behaviour of mass and horizon area as a function of temperature (also the solutions do not appear to possess an upper bound on |c m |).…”

“…For c m = 0, these are the Cvetič, Lü and Pope (CLP) BHs [6]. However, as found in the recent work [9], they possess a generalization with a nonvanishing magnetic field in the far field, which can also be described within the framework in Section 2.…”

“…Also we assume that a k (r) → c m in the same limit, (c m , v) being input parameters. This implies the existence of a nonvanishing asymptotic magnetic field, F θφ → − 1 2 c m sin θ, such that the parameter c m can be identified 5 with the magnetic flux at infinity through the base space S 2 of the S 1 fibration [9],…”

“…One should remark that the assumptions (i) and (ii) above are not related. There exist 'magnetized' solutions possessing a round sphere at infinity [9], and also vacuum BHs with a conformal boundary geometry (1.1). However, as we shall see in Section 4, the existence of a Killing spinor imposes that both (i) and (ii) should hold, i.e.…”

“…Remarkably, their extremal limit contains a subset of solutions that preserves some amount of supersymmetry [8]. An extension of the CLP BHs which possesses an extra parameter Φ m associated with a non-zero magnitude of the magnetic potential at infinity has been reported in the recent work [9].…”

We construct a new class of black hole solutions in five-dimensional Einstein-Maxwell-Chern-Simons theory with a negative cosmological constant. These configurations are cohomogeneity-1, with two equal-magnitude angular momenta. In the generic case, they possess a non-vanishing magnetic potential at infinity with a boundary metric which is the product of time and a squashed three-dimensional sphere. Both extremal and non-extremal black holes are studied. The non-extremal black holes satisfying a certain relation between electric charge, angular momenta and magnitude of the magnetic potential at infinity do not trivialize in the limit of vanishing event horizon size, becoming particle-like (non-topological) solitonic configurations. Among the extremal black holes, we show the existence of a new oneparameter family of supersymmetric solutions, which bifurcate from a critical Gutowski-Reall configuration.11 Their basic properties have been discussed in a different context in [35], [36]. 12 In understanding the limiting-v behaviour, some useful hints are provided by the nutty-instanton toy model in Appendix A.13 However, for black strings, the Gregory-Laflamme instability [37] implies the existence of a critical periodicity of theψ-coordinate for a given value of the mass [38].

Consistent embeddings are found of the minimal N = 2 and N = 3 gauged supergravities in four dimensions into its maximally supersymmetric, N = 8, counterpart with a dyonic ISO(7) gauging. These minimal truncations retain the metric along with relevant U(1) and SO(3) R-symmetry gauge fields selected from the ISO(7) ones. The remaining ISO(7) gauge fields are turned off, with subtleties introduced by the dyonic gauging, and the scalars are fixed to their expectation values at the N = 2 and N = 3 vacua of the N = 8 theory. Using the truncation formulae for massive type IIA supergravity on the sixsphere to D = 4 N = 8 ISO(7) supergravity, the minimal D = 4 N = 2 and N = 3 gauged supergravities are then uplifted consistently to ten dimensions.
