Abstract: Quasi-normal modes (QNMs) uniquely characterize the final black-hole. Till now, only the QNM frequency and damping time are used to test General relativity. In this work, we show explicitly that another property of the QNMs… read more here.

DOI: 10.1103/physrevd.104.064011
Abstract: We present a consistent way of coupling three-dimensional Maxwell Chern-Simons gravity theory with massless spin5 2 gauge fields. We first introduce the simplest hyper-Maxwell ChernSimons gravity containing two massless spin-2 fields coupled with a massless… read more here.

DOI: 10.1103/physrevd.104.064034
Abstract: Using gravitational wave observations to search for deviations from general relativity in the stronggravity regime has become an important research direction. One aspect of the strong gravity modifications to GR is parity violation. Chern Simons… read more here.

DOI: 10.1103/physrevd.107.084016
Abstract: Black hole superradiance provides a window into the dynamics of light scalar fields and their interactions close to a rotating black hole. Due to the rotation of the black hole, the amplitude of the scalar… read more here.

DOI: 10.1103/physrevd.96.065019
Abstract: We consider actions for particles and strings, including twistorial descriptions on 4d Minkowski and AdS$_5$ spacetimes from the point of view of co-adjoint orbits for the isometry group. We also consider the collective coordinate dynamics… read more here.

DOI: 10.3390/sym12122064
Abstract: We consider a family of new Higgs–Chern–Simons (HCS) gravity models in 2n+1 dimensions (n=1,2,3). This provides a generalization of the (usual) gravitational Chern–Simons (CS) gravities resulting from non-Abelian CS densities in all odd dimensions, which… read more here.
