Standard Perturbation Theory for Interacting Dark Sector cosmologies I: Breakdown of Einstein de Sitter kernels
Matheus Wolney, Gabriel Sampaio, Humberto Borges +2
Interacting dark sector (IDS) models provide a commonly explored extension of the standard CDM cosmology, allowing for non-gravitational energy--momentum exchange between cold…
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…
Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
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…
