Formation of small-scale structure in SUSY CDM
S. Hofmann, D. J. Schwarz, H. Stocker
The lightest supersymmetric particle, most likely the lightest neutralino, is one of the most prominent particle candidates for cold dark matter (CDM). We show that the primordial…
Particle production in time-dependent gravitational fields: the expanding mass shell
Sabine Hossenfelder, Dominik J. Schwarz, Walter Greiner
We compute the production of particles from the gravitational field of an expanding mass shell. Contrary to the situation of Hawking radiation and the production of cosmological pe…
Accelerated expansion without dark energy
Dominik J. Schwarz
The fact that the LambdaCDM model fits the observations does not necessarily imply the physical existence of `dark energy'. Dropping the assumption that cold dark matter (CDM) is a…
WKB approximation for inflationary cosmological perturbations
Jerome Martin, Dominik J. Schwarz
A new method for predicting inflationary cosmological perturbations, based on the Wentzel-Kramers-Brillouin (WKB) approximation, is presented. A general expression for the WKB scal…
Comment on "Density perturbations in the ekpyrotic scenario"
Jerome Martin, Patrick Peter, Nelson Pinto-Neto +1
In the paper ``Density perturbations in the ekpyrotic scenario'', it is argued that the expected spectrum of primordial perturbations should be scale invariant in this scenario. He…
Perturbations in the Ekpyrotic Scenarios
Patrick Peter, Jerome Martin, Nelson Pinto-Neto +1
With the new cosmological data gathered over the last few years, the inflationary paradigm has seen its predictions largely unchallenged. A recent proposal, called the ekpyrotic sc…
