Cosmological searches for a non-cold dark matter component
Stefano Gariazzo, Miguel Escudero, Roberta Diamanti +1
We explore an extended cosmological scenario where the dark matter is an admixture of cold and additional non-cold species. The mass and temperature of the non-cold dark matter par…
Cold dark matter plus not-so-clumpy dark relics
Roberta Diamanti, Shin'ichiro Ando, Stefano Gariazzo +2
Various particle physics models suggest that, besides the (nearly) cold dark matter that accounts for current observations, additional but sub-dominant dark relics might exist. The…
Dark matter protohalos in MSSM-9 and implications for direct and indirect detection
Roberta Diamanti, Maria Eugenia Cabrera Catalan, Shin'ichiro Ando
We study how the kinetic decoupling of dark matter (DM) within a minimal supersymmetric extension of the standard model, by adopting nine independent parameters (MSSM-9), could imp…
Constraining dark matter late-time energy injection: decays and p-wave annihilations
Roberta Diamanti, Laura Lopez-Honorez, Olga Mena +2
We use the latest cosmic microwave background (CMB) observations to provide updated constraints on the dark matter lifetime as well as on p-wave suppressed annihilation cross secti…
Dark Radiation and interacting scenarios
Roberta Diamanti, Elena Giusarma, Olga Mena +2
An extra dark radiation component can be present in the universe in the form of sterile neutrinos, axions or other very light degrees of freedom which may interact with the dark ma…
