Investigating a New Approach to Quasinormal Modes: Physics-Informed Neural Networks
Anele M Ncube, Gerhard E Harmsen, Alan S Cornell
Physics-informed neural networks (PINNs) hold the potential for supplementing the existing set of techniques for solving differential equations that emerge in the study of black ho…
Master equations and Quasi-normal modes of spin-3/2 fields in Schwarzschild (A)dS black hole spacetimes
Chun-Hung Chen, Hing-Tong Cho, Alan S. Cornell +1
In this work we consider spin-3/2 fields in Schwarzschild (A)dS black hole spacetimes. As this spacetime is different from the Ricci-flat cases, it is necessary to modify the covar…
Towards nonsingular rotating compact object in ghost-free infinite derivative gravity
Luca Buoninfante, Alan S. Cornell, Gerhard Harmsen +4
The vacuum solution of Einstein's theory of general relativity provides a rotating metric with a ring singularity, which is covered by the inner and outer horizons, and an ergo reg…
Quasi-normal modes of spin-3/2 fields in -dimensional Reissner-Nordström black hole spacetimes using the continued fraction method
Alan S. Cornell, Gerhard E. Harmsen
In a recent paper we calculated the field equations of spin-3/2 fields in a -dimensional Reissner-Nordström black hole spacetime whilst maintaining the gauge symmetry of the Rar…
Non-singular metric for an electrically charged point-source in ghost-free infinite derivative gravity
Luca Buoninfante, Gerhard Harmsen, Shubham Maheshwari +1
In this paper we will construct a linearized metric solution for an electrically charged system in a {\it ghost-free} infinite derivative theory of gravity which is valid in the en…
Quasi-normal modes and absorption probabilities of spin-3/2 fields in -dimensional Reissner-Nordström black hole spacetimes
C. -H. Chen, H. T. Cho, A. S. Cornell +2
In this paper we consider spin-3/2 fields in a -dimensional Reissner-Nordström black hole spacetime. As these spacetimes are not Ricci-flat, it is necessary to modify the covari…
