The Adiabatic Instability on Cosmology's Dark Side
Rachel Bean, Eanna E. Flanagan, Mark Trodden
We consider theories with a nontrivial coupling between the matter and dark energy sectors. We describe a small scale instability that can occur in such models when the coupling is…
Adiabatic instability in coupled dark energy-dark matter models
Rachel Bean, Eanna E. Flanagan, Mark Trodden
We consider theories in which there exists a nontrivial coupling between the dark matter sector and the sector responsible for the acceleration of the universe. Such theories can p…
Nonlinear growth in modified gravity theories of dark energy
Istvan Laszlo, Rachel Bean
Theoretical differences in the growth of structure offer the possibility that we might distinguish between modified gravity theories of dark energy and \LambdaCDM. A significant im…
The dynamical viability of scalar-tensor gravity theories
Nishant Agarwal, Rachel Bean
We establish the dynamical attractor behavior in scalar-tensor theories of dark energy, providing a powerful framework to analyze classes of theories, predicting common evolutionar…
A discriminating probe of gravity at cosmological scales
Pengjie Zhang, Michele Liguori, Rachel Bean +1
The standard cosmological model is based on general relativity and includes dark matter and dark energy. An important prediction of this model is a fixed relationship between the g…
Massive neutrinos and dark energy
Paolo Serra, Rachel Bean, Axel De La Macorra +1
We consider the impact of the Heidelberg-Moscow claim for a detection of neutrino mass on the determination of the dark energy equation of state. By combining the Heidelberg-Moscow…
