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 one-parameter family of supersymmetric solutions, which bifurcate from a critical Gutowski-Reall configuration. 2023-06-17T12:26:30Z 2023-06-17T12:26:30Z 2018-02-09 journal article 1029-8479 10.1007/JHEP02(2018)061 https://hdl.handle.net/20.500.14352/12014 http://dx.doi.org/10.1007/JHEP02(2018)061 https://link.springer.com/ eng StronGrHEP (690904) IRSES (606096) 1620 UID/MAT/04106/2013 PR26/16-20312 https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España Springer
