Revisiting Cosmological Constraints on Supersymmetric SuperWIMPs
Meera Deshpande, Jan Hamann, Dipan Sengupta +3
SuperWIMPs are extremely weakly interacting massive particles that inherit their relic abundance from late decays of frozen-out parent particles. Within supersymmetric models, grav…
Higher order corrections to the large scale matter power spectrum in the presence of massive neutrinos
Yvonne Y. Y. Wong
We present the first systematic derivation of the one-loop correction to the large scale matter power spectrum in a mixed cold+hot dark matter cosmology with subdominant massive ne…
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…
Cosmological constraints on neutrino plus axion hot dark matter: Update after WMAP-5
Steen Hannestad, Alessandro Mirizzi, Georg G. Raffelt +1
We update our previous constraints on two-component hot dark matter (axions and neutrinos), including the recent WMAP 5-year data release. Marginalising over sum m_nu provides m_a…
Cosmological constraints on neutrino plus axion hot dark matter
Steen Hannestad, Alessandro Mirizzi, Georg G. Raffelt +1
We use observations of the cosmological large-scale structure to derive limits on two-component hot dark matter consisting of mass-degenerate neutrinos and hadronic axions, both co…
