Source: Astronomy. 2023. Vol. 2, № 1. P. 47-57
Type: статьи в журналах
Date: 2023
Description: A simple phenomenological fit for the power spectrum of scalar (curvature) perturbations during inflation is proposed to analytically describe slow roll of inflaton and formation of primordial black h ... More

Type: статьи в журналах
Date: 2023
Description: A new (improved) model of inflation and primordial black hole (PBH) formation is proposed by combining the Starobinsky model of inflation, Appleby–Battye–Starobinsky (ABS) model of dark energy, and a ... More

Type: статьи в журналах

Description: E-type α-attractor models of single-field inflation were generalized further in order to accommodate production of primordial black holes (PBHs) via adding a near-inflection point to the inflaton scal ... More

Type: статьи в журналах
Date: 2022
Description: We propose and study the new (generalized) E-type α-attractor models of inflation, in order to include formation of primordial black holes (PBHs). The inflaton potential has a near-inflection point wh ... More

Type: статьи в журналах
Date: 2022
Description: In this paper, we adapted the Appleby–Battye–Starobinsky model of F(R) gravity towards describing double cosmological inflation and formation of primordial black holes with masses up to 1019 g in the ... More
Authors: Ketov, Sergei V.
Source: Universe. 2022. Vol. 8, № 7. P. 351 (1-6)
Type: статьи в журналах
Date: 2022
Description: A novel string-inspired gravitational theory in four spacetime dimensions is proposed as a sum of the modified (R+alpha R-2) gravity motivated by the Starobinsky inflation and the leading Bel-Robinson ... More
