Dark matters are Inert, or FIMPy, or WIMPy or UFOy: An inflationary gravitational particle production
Ayan Chakraborty, Debaprasad Maity, Rajesh Mondal
In this letter, we explore the phenomenological impact of inflationary gravitational particle production in the physics of Dark Matter (DM). Large-scale DM fluctuations generated d…
Nonminimal infrared gravitational reheating in light of ACT observation
Ayan Chakraborty, Debaprasad Maity, Rajesh Mondal
Inflation is known to produce large infrared scalar fluctuations. Further, if a scalar field is non-minimally coupled with gravity through , those infrared modes expe…
Constraining Reheating Temperature, Inflaton-SM Coupling and Dark Matter Mass in Light of ACT DR6 Observations
Rajesh Mondal, Sourav Mondal, Ayan Chakraborty
We explore the phenomenological implications of the latest Atacama Cosmology Telescope (ACT) DR6 observations, in combination with Planck 2018, BICEP/Keck 2018, and DESI, on the ph…
Freeze-in and freeze-out production of Higgs portal Majorana fermionic dark matter during and after reheating
Rajesh Mondal, Sourav Mondal, Toshifumi Yamada
In this paper, we investigate the production of Majorana fermionic dark matter (DM) via the Higgs portal, considering both freeze-in and freeze-out mechanisms during and after the…
Thermal and nonthermal dark matters with gravitational neutrino reheating
Md Riajul Haque, Debaprasad Maity, Rajesh Mondal
We have discussed in detail how neutrinos produced from inflaton solely through gravitational interaction can successfully reheat the universe. For this, we have introduced the wel…
