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…
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…
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…
Gravitational Waves Emission in Quadratic Gravity: longitudinal modes, angular momentum emission, and positivity of the radiated power
Matheus F. S. Alves, R. R. Cuzinatto, C. A. M. de Melo +2
In this paper, the emission of gravitational waves in quadratic gravity theory is examined. The wave equations for massless and massive perturbations are derived, followed by the c…
