Overview

Analysis reveals scalarization onset in qOS-extremal black holes with negative mass, suggesting instability ties to scalar clouds.

Key Points

  • Onset of scalarization observed in qOS-extremal black holes with negative mass, revealing new black hole characteristics.
  • A large scalar cloud at the horizon is noted, highlighting potential instability aspects of the black hole.
  • This analysis uses the Einstein–Gauss–Bonnet-scalar theory to examine black hole scalarization processes.
  • Implications include insights into Aretakis instability related to scalar clouds under specific conditions.
