Constraints on anisotropic cosmic expansion from supernovae
Benedict Bahr-Kalus, Dominik J. Schwarz, Marina Seikel +1
We test the isotropy of the expansion of the Universe by estimating the hemispherical anisotropy of supernova type Ia (SN Ia) Hubble diagrams at low redshifts (z<0.2). We compare t…
Does the CMB prefer a leptonic Universe?
Dominik J. Schwarz, Maik Stuke
Recent observations of the cosmic microwave background (CMB) at smallest angular scales and updated abundances of primordial elements, indicate an increase of the energy density an…
Reionization and the Cosmic Dawn with the Square Kilometre Array
Garrelt Mellema, León Koopmans, Filipe Abdalla +25
The Square Kilometre Array (SKA) will have a low frequency component (SKA-low) which has as one of its main science goals the study of the redshifted 21cm line from the earliest ph…
Newtonian versus relativistic cosmology
Samuel F. Flender, Dominik J. Schwarz
We show how the relativistic matter and velocity power spectra behave in different gauges. We construct a new gauge where both spectra coincide with Newtonian theory on all scales.…
Dissipation of dark matter
Hermano Velten, Dominik J. Schwarz
Fluids often display dissipative properties. We explore dissipation in the form of bulk viscosity in the cold dark matter fluid. We constrain this model using current data from sup…
The Oddly Quiet Universe: How the CMB challenges cosmology's standard model
Glenn D. Starkman, Craig J. Copi, Dragan Huterer +1
We discuss selected large-scale anomalies in the maps of temperature anisotropies in the cosmic microwave background. Specfically, these include alignments of the largest modes of…
