我们对文[1]中发现的静态超对称AdS4黑洞作了进一步的阐述，深入研究了存在Fayet-Iliopoulos项的N=2规范超引力中球对称的BPS约束。我们找到了能保存原始八种超荷中的两种的致命自旋，并研究了没有裸奇点的真正黑洞的条件。视界的存在与标量不是常数的要求密切相关，而是以调和函数的形式给出，类似于无规超重力中的吸引子流。黑洞的电荷取决于电磁测量的选择，纯电子测量只有磁荷。最后，我们展示了如何将这些黑洞嵌入到N=8超重力中，从而嵌入到M理论中。
We elaborate further on the static supersymmetric AdS4 black holes found in [1], investigating thoroughly the BPS constraints for spherical symmetry in N = 2 gauged supergravity in the presence of Fayet-Iliopoulos terms. We find Killing spinors that preserve two of the original eight supercharges and investigate the conditions for genuine black holes free of naked singularities. The existence of a horizon is intimately related with the requirement that the scalars are not constant, but given in terms of harmonic functions in analogy to the attractor flow in ungauged supergravity. The black hole charges depend on the choice of the electromagnetic gauging, with only magnetic charges for purely electric gaugings. Finally we show how these black holes can be embedded in N = 8 supergravity and thus in M-theory.
