On correlated noise in the LIGO-Virgo network: a test of the stochastic gravitational-wave background hypothesis
S. C. Ulhoa, B. C. C. Carneiro, F. L. Carneiro +1
We revisit the inter-detector cross-correlation criterion used in gravitational-wave validation by extending the analysis of Creswell et al.~\cite{Creswell2017} to nine LIGO--Virgo…
On the Gravitational Energy of Axial Perturbations in Regular Black Holes
S. C. Ulhoa, F. L. Carneiro, B. C. C. Carneiro
The article deals with the gravitational energy associated with axial perturbations of regular black holes. We review the stability of the geometry under odd-parity perturbations a…
On the Gravitational Angular Momentum of Axial Perturbations of a Regular Black Hole
S. C. Ulhoa, F. L. Carneiro, B. C. C. Carneiro
This Letter deals with the gravitational angular momentum carried by axial (odd-parity) perturbations of the Bardeen regular black hole within the teleparallel equivalent of genera…
On Nanocones as a Gravitational Analog System
F. L. Carneiro, B. C. C. Carneiro, D. L. Azevedo +1
This study delves into the fundamental properties of graphene and boron nitride (BN) nanostructures, exploring their torsional energy characteristics within the framework of Telepa…
