Gravitational Foundations and Exact Solutions in -Dimensional Fractional Cosmology
S. M. M. Rasouli, J. Marto, D. A. V. Oliveira +1
Three theoretically plausible techniques to developing a fractional scalar field cosmological model are pointed in this paper; the time-dependent kernel weighted action being then…
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…
Gravitational waves from primordial black hole dominance: The effect of inflaton decay rate
Daniel del-Corral, K. Sravan Kumar, João Marto
In this work, we explore primordial black holes (PBH) formation scenario during the post-inflationary preheating stage dominated by the inflaton field. We consider, in particular,…
