arxiv.org/abs/2512.12557 Constraint on magnetized black bounce spacetime from HFQPOs data and the selection of resonance models via information criterion
The study models charged-particle motion in a magnetized Simpson-Visser black bounce spacetime and fits it to HFQPO data from three microquasars. Information criteria favor the ER8 resonance model, and the fits permit a regularization parameter 0 ≤ a/M < 0.736, consistent with a regular black hole.
