Particlelike solutions of the Einstein-Dirac-Higgs equations: ground, excited, and many-fermion states
Reinosuke Kusano, Keith Horne, Peter E. D. Leith +2
We present an extended study of the gravitationally localized soliton-like solutions to the minimally-coupled Einstein-Dirac-Higgs equations, embedded in asymptotically Minkowski s…

Critical analysis of some weak-field Weyl conformal gravity solutions
Miguel Yulo Asuncion, Reinosuke Kusano
The field equations of Conformal Gravity (CG) are constructed from fourth-order derivatives of the metric. While the second-order field equations of General Relativity (GR) reduce…

Beyond black hole spectroscopy: Quasinormal mode contamination by massless scalars
Miguel Yulo Asuncion, Giovanni D'Addario, Thomas P. Sotiriou
Testing General Relativity (GR) with black hole ringdowns has conventionally focused on attempting to detect shifts away from the quasinormal mode (QNM) frequencies of the Kerr met…
