Detecting a Lorentz-Violating Field in Cosmology
Baojiu Li, David F. Mota, John D. Barrow
We consider cosmology in the Einstein-aether theory (the generally covariant theory of gravitation coupled to a dynamical timelike Lorentz-violating vector field) with a linear aet…
Astrophysical Configurations with Background Cosmology: Probing Dark Energy at Astrophysical Scales
Andres Balaguera-Antolinez, David F. Mota, Marek Nowakowski
We explore the effects of a positive cosmological constant on astrophysical and cosmological configurations described by a polytropic equation of state. We derive the conditions fo…
An Improved Semi-Analytical Spherical Collapse Model for Non-linear Density Evolution
Douglas J. Shaw, David F. Mota
We derive a semi-analytical extension of the spherical collapse model of structure formation that takes account of the effects of deviations from spherical symmetry and shell cross…
