Axion hot dark matter bounds

G. Raffelt, S. Hannestad, A. Mirizzi +1

We derive cosmological limits on two-component hot dark matter consisting of neutrinos and axions. We restrict the large-scale structure data to the safely linear regime, excluding…

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…
