Abstract:
We show how the model of pseudo-complex general relativity can be tested
using gravitational wave signals from coalescing compact objects. The model,
which agrees with Einstein gravity in the weak-field limit, diverges
dramatically in the near-horizon regime, with certain parameter ranges
excluding the existence of black holes. We show that simple limits can be
placed on the model in both the inspiral and ringdown phase of coalescing
compact objects. We discuss further how these bounds relate to current
observational limits. In particular, for minimal scenarios previously
considered in the literature, gravitational wave observations are able to
constrain pseudo-complex general relativity parameters to values that require
the existence of black hole horizons.
