Hairless Black Hole by Superradiance
Sebastian Garcia-Saenz, Guangzhou Guo, Peng Wang +1
We investigate the interplaying effects of black hole scalarization and superradiance in the context of the Einstein-Maxwell-scalar model, with the scalar field possessing electric…

Stable long-term evolution in numerical relativity
Sebastian Garcia-Saenz, Guangzhou Guo, Peng Wang +1
We report on the potential occurrence of a numerical instability in the long-time simulation of black holes using the Baumgarte-Shapiro-Shibata-Nakamura formulation of numerical re…

Black hole accretion of scalar clouds with spontaneous symmetry breaking
Sebastian Garcia-Saenz, Guangzhou Guo, Peng Wang +1
Spontaneous scalarization of black holes typically occurs through the condensation of a scalar field, with the field evolving from a -symmetric phase into a symmetry-breaking…
