Anisotropic models in LQC with GBP polymerisation
D. A. Cook, A. Olimpieri, I. P. R. Baranov +2
Polymer models are effective in describing quantum gravity effects around the initial singularity, leading to its replacement by bouncing surfaces on which the curvature and densit…
Thermodynamics of effective loop quantum black holes
F. G. Menezes, H. A. Borges, I. P. R. Baranov +1
We study the thermodynamics of a non-singular black hole model with effective quantum corrections motivated by Loop Quantum Gravity (LQG). The effective geometry has a transition s…
Dark sector interactions in light of weak lensing data
M. Benetti, P. T. Z. Seidel, C. Pigozzo +3
The current observational tensions in the standard cosmological model have reinforced the research on dynamical dark energy, in particular on models with non-gravitational interact…
Gravitational waves from binary axionic black holes
J. A. de Freitas Pacheco, S. Carneiro, J. C. Fabris
In a recent paper we have shown that a minimally coupled, self-interacting scalar field of mass can form black holes of mass (in Planck units). If dark matter…
Non-adiabatic perturbations in decaying vacuum cosmology
W. Zimdahl, H. A. Borges, S. Carneiro +2
We investigate a spatially flat Friedmann-Lemaître-Robertson-Walker cosmology in which a decaying vacuum term causes matter production at late times. Assuming a decay proportional…
Evolution of density perturbations in decaying vacuum cosmology: The case of non-zero perturbations in the cosmological term
H. A. Borges, S. Carneiro, J. C. Fabris
We extend the results of a previous paper where a model of interacting dark energy, with a cosmological term decaying linearly with the Hubble parameter, is tested against the obse…
