Astrophysical Constraints on Dark Energy
Chiu Man Ho, Stephen D. H. Hsu
Dark energy (i.e., a cosmological constant) leads, in the Newtonian approximation, to a repulsive force which grows linearly with distance and which can have astrophysical conseque…

Dark Energy, with Signatures
Sourish Dutta, Stephen D. H. Hsu, Robert J. Scherrer
We propose a class of simple dark energy models which predict a late-time dark radiation component and a distinctive time-dependent equation of state for redshift . T…

Dark radiation as a signature of dark energy
Sourish Dutta, Stephen D. H. Hsu, David Reeb +1
We propose a simple dark energy model with the following properties: the model predicts a late-time dark radiation component that is not ruled out by current observational data, bu…
