Evolving Dark Energy Is Vacuum Energy After All
Dong Ha Lee, Carsten van de Bruck, Eleonora Di Valentino +2
We investigate a physically motivated model of dynamical dark energy arising from the non-perturbative topological structure of the Quantum Chromodynamics (QCD) vacuum. The model i…
Non-linear Structure Formation in Planck+DESI Favoured Interacting Dark Energy Cosmologies
Yuejia Zhai, Carsten van de Bruck, Eleonora Di Valentino +2
Following our previous work constraining interacting dark energy (IDE) models, which showed their potential to alleviate the Hubble tension, in this work we investigate the non-lin…
A no-go theorem in bumblebee vector-tensor cosmology
Carsten van de Bruck, Mohammad Ali Gorji, Nils A. Nilsson +2
Bumblebee models, a class of vector-tensor theories in which a vector field acquires a nonzero vacuum expectation value that spontaneously breaks spacetime symmetries, are ubiquito…
Model-Independent Test of Prerecombination New Physics: Measuring the Sound Horizon with Gravitational Wave Standard Sirens and the Baryon Acoustic Oscillation Angular Scale
William Giarè, Jonathan Betts, Carsten van de Bruck +1
In a broad class of cosmological models where spacetime is described by a pseudo-Riemannian manifold, photons propagate along null geodesics, and their number is conserved, upcomin…
Bouncing cosmologies in the presence of a Dirac-Born-Infeld field
Mariam Campbell, Richard Daniel, Peter K. S. Dunsby +1
We perform a detailed dynamical system analysis for the behaviour of a Dirac-Born-Infeld (DBI) field in a spatially closed Friedmann-Lemaître-Robertson-Walker (FLRW) cosmology. The…
Scalar field dark matter with time-varying equation of state
Gaspard Poulot, Elsa M. Teixeira, Carsten van de Bruck +1
We propose a new model of scalar field dark matter interacting with dark energy. Adopting a fluid description of the dark matter field in the regime of rapid oscillations, we find…
