Evolution of Cyclic Mixmaster Universes with Non-comoving Radiation
Chandrima Ganguly, John D. Barrow
We study a model of a cyclic, spatially homogeneous, anisotropic 'mixmaster' universe of Bianchi type IX, containing a radiation field with non-comoving ('tilted' with respect to t…
Cosmological Models in Energy-Momentum-Squared Gravity
Charles V. R. Board, John D. Barrow
We study the cosmological effects of adding terms of higher-order in the usual energy-momentum tensor to the matter lagrangian of general relativity. This is in contrast to most st…
Stability of the Kasner Universe in f(T) Gravity
Andronikos Paliathanasis, Jackson Levi Said, John D. Barrow
gravity offers an alternative context in which to consider gravitational interactions where torsion, rather than curvature, is the mechanism by which gravitation is communic…
Large-scale Stability and Astronomical Constraints for Coupled Dark-Energy Models
Weiqiang Yang, Supriya Pan, John D. Barrow
We study large-scale inhomogeneous perturbations and instabilities of interacting dark energy (IDE) models. Past analysis of large-scale perturbative instabilities, has shown that…
The Shape of Bouncing Universes
John D. Barrow, Chandrima Ganguly
What happens to the most general closed oscillating universes in general relativity? We sketch the development of interest in cyclic universes from the early work of Friedmann and…
Cyclic Mixmaster Universes
John D. Barrow, Chandrima Ganguly
We investigate the behaviour of bouncing Bianchi type IX `Mixmaster' universes in general relativity. This generalises all previous studies of the cyclic behaviour of closed spatia…
Probing the Gravitational Dependence of the Fine-Structure Constant from Observations of White Dwarf Stars
Matthew B. Bainbridge, Martin A. Barstow, Nicole Reindl +12
Hot white dwarf stars are the ideal probe for a relationship between the fine-structure constant and strong gravitational fields, providing us with an opportunity for a direct obse…
