According to the inflationary Universe scenario the Universe in the very early stages of its
evolution was exponentially expanding in the unstable vacuumlike state. At the end of the …

This paper outlines astrophysical issues related to the long-term fate of the universe. The
authors consider the evolution of planets, stars, stellar populations, galaxies, and the …

Cosmological first-order phase transitions (1stOPTs) are said to be strongly supercooled
when the nucleation temperature is much smaller than the critical temperature. These are …

For primordial perturbations, deviations from Gaussian statistics on the tail of the probability
distribution can be associated with non-perturbative effects of inflation. In this paper, we …

The Early Universe has become the standard reference on forefront topics in cosmology,
particularly to the early history of the Universe. Subjects covered include primordial …

We reexamine production of primordial black holes in a supercooled phase transition. While
a mere overdensity associated with a surviving false-vacuum patch does not imply formation …

We investigate the cosmological consequences of a phase transition which is driven
primarily by slow nucleation of bubbles of the new phase via the effectively zero temperature …

We consider chaotic inflation in the theories with the effective potentials which at large φ
behave either as φ n or as e α φ. In such theories inflationary domains containing a …

Primordial black holes (PBHs) are a viable candidate for dark matter if the PBH masses are
in the currently unconstrained “sublunar” mass range. We revisit the possibility that PBHs …

A bstract Light primordial black holes (PBHs) with masses smaller than 10 9 g (10− 24 M⊙)
evaporate before the onset of Big-Bang nucleosynthesis, rendering their detection rather …
