Weighing the spatial and temporal fluctuations of the dark universe
Pengjie Zhang, Rachel Bean, Michele Liguori +1
A generic prediction of the standard cosmology, based on general relativity (GR), dark matter and the cosmological constant (and more generally, smooth dark energy), is that, the t…
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…
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…
Cosmological constraints in the presence of ionizing and resonance radiation at recombination
Rachel Bean, Alessandro Melchiorri, Joe Silk
With the recent measurement of full sky cosmic microwave background polarization from WMAP, key cosmological degeneracies have been broken, allowing tighter constraints to be place…
