A new mechanism for primordial black hole formation during reheating
Luis E. Padilla, Juan Carlos Hidalgo, Karim A. Malik
The Reheating process at the end of inflation is often modeled by an oscillating scalar field which shows a background dust-like behaviour, prompting the analysis of gravitational…
Long-wavelength non-linear perturbations of a complex scalar field
Luis E. Padilla, Juan Carlos Hidalgo, Darío Núñez
We study the evolution of nonlinear superhorizon perturbations in a universe dominated by a complex scalar field. The analysis is performed adopting the gradient expansion approach…
Rotation curves with the multistate Scalar Field Dark Matter model
Jordi Solís-López, Luis E. Padilla, Tonatiuh Matos
We use the concept of co-added rotation curves of Salucci et al. to investigate the properties of axi-symmetric multistate Scalar Field Dark Matter halos in low surface brightness…
Complex Scalar Field Reheating and Primordial Black Hole production
Karim Carrion, Juan Carlos Hidalgo, Ariadna Montiel +1
We study perturbations of a complex scalar field during reheating with no self-interaction in the regime , when the scalar field has a fast oscillatory behaviour (close to…
