Near-inflection point inflation and production of dark matter during reheating
Anish Ghoshal, Gaetano Lambiase, Supratik Pal +2
We study slow roll single field inflationary scenario and the production of non-thermal fermionic dark matter, together with standard model Higgs, during reheating. For the inflati…

Constraints on Tsallis Cosmology from Big Bang Nucleosynthesis and Dark Matter Freeze-out
Anish Ghoshal, Gaetano Lambiase
We consider Tsallis cosmology as an approach to thermodynamic gravity and derive the bound on the Tsallis parameter to be by using the constraints derived from the formation…

Primordial Gravitational Wave Signals in Modified Cosmologies
Nicolás Bernal, Anish Ghoshal, Fazlollah Hajkarim +1
Modified expansion rates in the early Universe prior to big bang nucleosynthesis are common in modified gravity theories, and can have a significant impact on the generation of dar…
