Multi-messenger constraints on dark matter annihilation into electron-positron pairs
Maneenate Wechakama, Yago Ascasibar
We investigate the production of electrons and positrons in the Milky Way within the context of dark matter annihilation. Upper limits on the relevant cross-section are obtained by…
Non-adiabatic perturbations in Ricci dark energy model
Khamphee Karwan, Thiti Thitapura
We show that the non-adiabatic perturbations between Ricci dark energy and matter can grow both on superhorizon and subhorizon scales, and these non-adiabatic perturbations on subh…
Dynamics of entropy perturbations in assisted dark energy with mixed kinetic terms
Khamphee Karwan
We study dynamics of entropy perturbations in the two-field assisted dark energy model. Based on the scenario of assisted dark energy, in which one scalar field is subdominant comp…
CMB constraints on noncommutative geometry during inflation
Khamphee Karwan
We investigate the primordial power spectrum of the density perturbations based on the assumption that spacetime is noncommutative in the early stage of inflation. Due to the space…
