Model- and calibration-independent test of cosmic acceleration
Marina Seikel, Dominik J. Schwarz
We present a calibration-independent test of the accelerated expansion of the universe using supernova type Ia data. The test is also model-independent in the sense that no assumpt…
No large-angle correlations on the non-Galactic microwave sky
Craig J. Copi, Dragan Huterer, Dominik J. Schwarz +1
We investigate the angular two-point correlation function of temperature in the WMAP maps. Updating and extending earlier results, we confirm the lack of correlations outside the G…
The effect of early dark matter halos on reionization
Aravind Natarajan, Dominik J. Schwarz
The annihilation of dark matter particles releases energy, ionizing some of the gas in the Universe. We investigate the effect of dark matter halos on reionization. We show that th…
Is dark energy an effect of averaging?
Nan Li, Marina Seikel, Dominik J. Schwarz
The present standard model of cosmology states that the known particles carry only a tiny fraction of total mass and energy of the Universe. Rather, unknown dark matter and dark en…
How strong is the evidence for accelerated expansion?
Marina Seikel, Dominik J. Schwarz
We test the present expansion of the universe using supernova type Ia data without making any assumptions about the matter and energy content of the universe or about the parameter…
Scale dependence of cosmological backreaction
Nan Li, Dominik J. Schwarz
Due to the non-commutation of spatial averaging and temporal evolution, inhomogeneities and anisotropies (cosmic structures) influence the evolution of the averaged Universe via th…
