Brans-Dicke-like field for co-varying and : observational constraints
J. Bezerra-Sobrinho, R. R. Cuzinatto, L. G. Medeiros +1
Ref. [Symmetry 15 (2023) 709] introduced a Brans-Dicke-like framework wherein the scalar field is composed of both and which, for this reason, co-vary according to $c^…

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…
