Nonlinear corrections to the cosmological matter power spectrum and scale-dependent galaxy bias: implications for parameter estimation
Jan Hamann, Steen Hannestad, Alessandro Melchiorri +1
We explore and compare the performances of two nonlinear correction and scale-dependent biasing models for the extraction of cosmological information from galaxy power spectrum dat…
Observational bounds on the cosmic radiation density
Jan Hamann, Steen Hannestad, Georg G. Raffelt +1
We consider the inference of the cosmic radiation density, traditionally parameterised as the effective number of neutrino species N_eff, from precision cosmological data. Paying p…
How robust are inflation model and dark matter constraints from cosmological data?
Jan Hamann, Steen Hannestad, Martin S. Sloth +1
High-precision data from observation of the cosmic microwave background and the large scale structure of the universe provide very tight constraints on the effective parameters tha…
