Equation of State for Dark Energy in Modified Gravity Theories
Modified theories of gravity Dark energy Cosmology
2012/2/21
We explore the equation of state (EoS) for dark energy $w_{\mathrm{DE}}$ in modified gravitational theories to explain the current accelerated expansion of the universe. We explicitly demonstrate that...

Beyond Einstein: Cosmological Model Independent Modified Gravity
2011/10/8
Model-independent parametrisations of modified gravity have attracted a lot of attention over the past few years; numerous combinations of experiments and observables have been suggested to constrain ...
Towards a fully consistent parameterization of modified gravity

2011/9/27
There is a distinct possibility that current and future cosmological data can be used to constrain Einstein's theory of gravity on the very largest scales. To be able to do this in a model-independent...

A recent study of the satellite galaxies surrounding the Milky Way casts doubt on existing models of dark matter — according to its authors in Germany, Austria and Australia. The locations of the gala...
