BICEP/Keck Constraints on Attractor Models of Inflation and Reheating
John Ellis, Marcos A. G. Garcia, Dimitri V. Nanopoulos +2
Recent BICEP/Keck data on the cosmic microwave background, in combination with previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar perturbation s…
Slow and Safe Gravitinos
Emilian Dudas, Marcos A. G. Garcia, Yann Mambrini +3
It has been argued that supergravity models of inflation with vanishing sound speeds, , lead to an unbounded growth in the production rate of gravitinos. We consider several m…
Inflaton Oscillations and Post-Inflationary Reheating
Marcos A. G. Garcia, Kunio Kaneta, Yann Mambrini +1
We analyze in detail the perturbative decay of the inflaton oscillating about a generic form of its potential , taking into account the effects of non-instantaneous reh…
Reheating and Dark Matter Production
Marcos A. G. Garcia
A concise summary of out-of-equilibrium dark matter production during post-inflationary reheating is presented. We show that the dark matter relic abundance is in general sensitive…
How warm are non-thermal relics? Lyman- bounds on out-of-equilibrium dark matter
Guillermo Ballesteros, Marcos A. G. Garcia, Mathias Pierre
We investigate the power spectrum of Non-Cold Dark Matter (NCDM) produced in a state out of thermal equilibrium. We consider dark matter production from the decay of scalar condens…
Building Models of Inflation in No-Scale Supergravity
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +3
After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity. W…
