Big Bang nucleosynthesis with a stiff fluid
Sourish Dutta, Robert J. Scherrer
Models that lead to a cosmological stiff fluid component, with a density that scales as , where is the scale factor, have been proposed recently in a variety of c…

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…

Decaying dark matter mimicking time-varying dark energy
Sourish Dutta, Robert J. Scherrer
A CDM model with dark matter that decays into inert relativistic energy on a timescale longer than the Hubble time will produce an expansion history that can be misinterpreted a…
