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…
Unparticle constraints from SN1987A
Steen Hannestad, Georg Raffelt, Yvonne Y. Y. Wong
The existence of an unparticle sector, weakly coupled to the standard model, would have a profound impact on supernova (SN) physics. Emission of energy into the unparticle sector f…
