Anisotropic universe with anisotropic dark energy
Anshul Verma, Pavan K. Aluri, David F. Mota
We investigate the anisotropic parameterization of the dark energy equation of state within the framework of an axisymmetric (planar) Bianchi-I universe. Using the latest Pantheon+…
Gravitational wave pulse and memory effects for hairy Kiselev black hole and its analogy with Bondi-Sachs formalism
H. Hadi, Amin Rezaei Akbarieh, David F. Mota
The investigation of non-vacuum cosmological backgrounds containing black holes is greatly enhanced by the Kiselev solution. This solution plays a crucial role in understanding the…
Gravitational waves from dark domain walls
Øyvind Christiansen, Julian Adamek, Farbod Hassani +1
For most of cosmic history, the evolution of our Universe has been governed by the physics of a 'dark sector', consisting of dark matter and dark energy, whose properties are only…
Ellipsoidal configurations in the de Sitter spacetime
A. Balaguera-Antolinez, D. F. Mota, M. Nowakowski
The cosmological constant modifies certain properties of large astrophysical rotating configurations with ellipsoidal geometries, provided the objects are not too compact. Assu…
Cosmology of Mass-Varying Neutrinos Driven by Quintessence: Theory and Observations
A. W. Brookfield, C. van de Bruck, D. F. Mota +1
The effects of mass-varying neutrinos on cosmic microwave background (CMB) anisotropies and large scale structures (LSS) are studied. In these models, dark energy and neutrinos are…
Large Scale Structure in Bekenstein's theory of relativistic Modified Newtonian Dynamics
C. Skordis, D. F. Mota, P. G. Ferreira +1
A relativistic theory of modified gravity has been recently proposed by Bekenstein. The tensor field in Einstein's theory of gravity is replaced by a scalar, a vector, and a tensor…
