This paper presents a research framework for investigating rotating charged quantum Oppenheimer-Snyder black holes within the Einstein-Gauss-Bonnet-scalar theory, focusing on the interplay between Gauss-Bonnet scalarization and superradiant instability. It proposes a systematic approach to construct scalarized rotating black hole solutions, analyze their stability, and investigate superradiant amplification of bosonic fields.
Key findings
Proposes a theoretical framework for constructing rotating cqOS-black holes in EGBS theory.
Determines conditions for GB scalarization onset in rotating cqOS spacetimes.
Investigates superradiant instability of scalar fields in these backgrounds.
Constructs numerical solutions for fully nonlinear scalarized rotating cqOS-black holes.
Analyzes observational signatures including quasinormal modes, shadows, and gravitational wave emission.
Limitations & open questions
Rotating generalizations of cqOS-black holes remain unexplored
Effect of pre-existing scalarization on superradiant amplification is poorly understood
