Cosmological constraints on neutrino plus axion hot dark matter: update after WMAP-5

Year: 2008

Type: article

Abstract: We update our previous constraints on two-component hot dark matter (axions and neutrinos), including the recent WMAP five-year data release. Marginalizing over provides m a <1.02 eV (95% C.L.) for the axion mass. In the absence of axions we find eV (95% C.L.).
