Self consistent estimates of magnetic fields from reheating
Esteban Calzetta, Alejandra Kandus
We investigate the generation of primordial magnetic fields from stochastic currents created by the cosmological transition from inflation to reheating. We consider N charged scala…
Cosmologial magnetic field amplification around z~100
Esteban A. Calzetta, Alejandra Kandus
We study the corrections to the conformal evolution of primordial magnetic fields after recombination, produced by the fall of the ionized fraction of matter into the dark matter g…
Primordial magnetic fields induced by cosmological particle creation
Esteban A. Calzetta, Alejandra Kandus, Francisco D. Mazzitelli
We study the primordial magnetic field generated by stochastic currents produced by scalar charged particles created at the beginning of the radiation dominated epoch. We find that…
Mode - mode coupling and primordial fluctuations
Esteban Calzetta, Mariana Grana
We consider the influence of mode - mode coupling in the inflaton field on the spectrum of primordial fluctuations. To this end, we formulate a phenomenological model where the inf…
Spherically Symmetric Non Linear Structures
Esteban A. Calzetta, Alejandra Kandus
We present an analytical method to extract observational predictions about non linear evolution of perturbations in a Tolman Universe. We assume no a priori profile for them. We so…
