Fermion (non)reheating with a quartic inflaton potential
Nabeen Bhusal, Ernesto Chávez M., Marcos A. G. Garcia +2
Any viable inflationary model must account for reheating of the universe prior to the onset of primordial nucleosynthesis. In this work, we study the (p)reheating mechanism for an…

Gravitational wave signatures of post-fragmentation reheating
Marcos A. G. Garcia, Mathias Pierre
After cosmic inflation, coherent oscillations of the inflaton field about a monomial potential result in an expansion phase characterized by a stiff equation-of-stat…

Impact of Dark Sector Preheating on CMB Observables
Marcos A. G. Garcia, Aline Pereyra-Flores
The prediction of a nearly scale-invariant spectrum of curvature and tensor fluctuations is among the main features of cosmic inflation. The current measurements of the primordial…
