Cannibal dark matter decoupled from standard model: cosmological constraints
Avirup Ghosh, Sourav Gope, Satyanarayan Mukhopadhyay
An internally thermalized dark matter (DM) with only gravitational interaction with the standard model (SM) particles at low temperatures, may undergo number-changing self-scatteri…
Momentum distribution of dark matter produced in inflaton decay: effect of inflaton mediated scatterings
Avirup Ghosh, Satyanarayan Mukhopadhyay
Post-inflationary reheating is a widely discussed mechanism for non-thermal production of dark matter (DM). In this scenario the momentum distribution of the produced DM particles…
A general study of decaying scalar dark matter: existing limits and projected radio signals at the SKA
Koushik Dutta, Avirup Ghosh, Arpan Kar +1
We consider a decaying scalar dark matter (DM) with mass in the range 10 GeV - 10 TeV and vary the branching ratios of all possible two-body SM final states (excluding and in…
