Higher-order gravity models: corrections up to cubic curvature invariants and inflation
C. M. G. R. Morais, G. Rodrigues-da-Silva, L. G. Medeiros
We construct a higher-order gravity model including all corrections up to mass dimension six. Starting from the Jordan frame, we derive the field equations and specialize to the FL…
Critical masses and numerical computation of massive scalar quasinormal modes in Schwarzschild black holes
Matheus F. S. Alves, Bruno P. Pônquio, L. G. Medeiros
We present a comprehensive analysis of the quasinormal modes (QNMs) of a massive scalar field in Schwarzschild spacetime using two complementary numerical techniques: the Hill-dete…
Gravitational waveforms from inspiraling compact binaries in quadratic gravity and their parameterized post-Einstein characterization
Matheus F. S. Alves, L. G. Medeiros, Davi C. Rodrigues
We investigate gravitational waveforms from the inspiral phase of compact binary systems within the framework of quadratic gravity and map their deviations from general relativity…
Gauges for quadratic gravity: the extended transverse gauge and the energy-momentum tensor of the massive spin-2 field
Matheus F. S. Alves, L. G. Medeiros, Davi C. Rodrigues
We study the 4D Einstein-Hilbert action extension based on the square of the curvature tensors. Analyses of gauge and perturbation modes are often done considering the Teyssandier…
