The maximum sizes of large scale structures in alternative theories of gravity
Sourav Bhattacharya, Konstantinos F. Dialektopoulos, Antonio Enea Romano +2
The maximum size of a cosmic structure is given by the maximum turnaround radius -- the scale where the attraction due to its mass is balanced by the repulsion due to dark energy.…
The Geometry Of Modified Newtonian Dynamics
C. Skordis, T. G. Zlosnik
Modified Newtonian Dynamics is an empirical modification to Poisson's equation which has had success in accounting for the `gravitational field' in a variety of astrophysical s…
The initial conditions of the universe: how much isocurvature is allowed?
M. Bucher, J. Dunkley, P. G. Ferreira +2
We investigate the constraints imposed by the current data on correlated mixtures of adiabatic and non-adiabatic primordial perturbations. We discover subtle flat directions in par…
Natural Quintessence and Large Extra Dimensions
A. Albrecht, C. P. Burgess, F. Ravndal +1
We examine the late-time (nucleosynthesis and later) cosmological implications of brane-world scenarios having large (millimeter sized) extra dimensions. In particular, recent prop…
Exponentially Large Extra Dimensions
A. Albrecht, C. P. Burgess, F. Ravndal +1
We show how the presence of a very light scalar with a cubic self-interaction in six dimensions can stabilize the extra dimensions at radii which are naturally exponentially large,…
