A note on oscillons: non-negligible metric fluctuations during preheating
Daniel del-Corral, Paolo Gondolo, K. Sravan Kumar +1
The dominant lattice approach to post-inflationary preheating and oscillon formation evolves an inhomogeneous inflaton field on a spatially homogeneous Friedmann-Lemaître-Robertson…
Gertsenshtein effect on the spacetime curved by background magnetic field with geometric optics
Ryutaro Tomomatsu, Teruaki Suyama, Paolo Gondolo
When electromagnetic (or gravitational) waves propagate in the presence of a background magnetic field, a portion of the waves converts into gravitational (or electromagnetic) wave…
Primordial black holes through preheating instabilities in -attractor models
Daniel del-Corral, Paolo Gondolo, K. Sravan Kumar +1
In this work, we explore the production of primordial black holes (PBHs) within the context of -attractor inflationary models, focusing on the preheating phase following inflati…
Scalar-Induced Gravitational Waves from self-resonant preheating in -attractor models
Daniel del-Corral, Paolo Gondolo, K. Sravan Kumar +1
After the inflationary phase, the universe enters the preheating phase, during which the inflaton field rolls down its potential and oscillates. When the potential significantly de…
Revisiting primordial black holes formation from preheating instabilities: the case of Starobinsky inflation
Daniel del-Corral, Paolo Gondolo, K. Sravan Kumar +1
In recent years, the formation of primordial black holes (PBH) in the early universe inflationary cosmology has garnered significant attention. One plausible scenario for primordia…
