Inflation is the leading candidate to explain the initial conditions for the Universe we see today. It consists of an epoch of accelerated expansion, and regularly solves many problems with the Big Bang theory. Non-Gaussianity of the primordial curvature perturbation can potentially be used to discriminate between competing models and provide an understanding of the mechanism of inflation. Whilst inflation is believed to have lasted at least 50 - 60 e-folds, constraints from sources such as… 



Generating Primordial Black Holes Via Hilltop-Type Inflation Models

It has been shown that black holes would have formed in the early Universe if, on any given scale, the spectral amplitude of the cosmic microwave background exceeds P{sub {zeta}}{approx}10{sup -4}.

Constraints from primordial black hole formation at the end of inflation

Primordial black hole (PBH) abundance limits constrain the primordial power spectrum, and hence models of inflation, on scales far smaller than those probed by cosmological observations. Single field

The Primordial black hole mass spectrum

We examine what mass spectrum of primordial black holes should result if the early universe consisted of small density fluctuations superposed on a Friedmann background. It is shown that only a

Inflationary universe: A possible solution to the horizon and flatness problems

The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that

Primordial black holes from temporally enhanced curvature perturbation

Scalar field with generalized kinetic interactions metamorphoses depending on its field value, ranging from a cosmological constant to stiff matter. We show that such a scalar field can give rise to

Constraints on small-scale cosmological perturbations from gamma-ray searches for dark matter

Events like inflation or phase transitions can produce large density perturbations on very small scales in the early Universe. Probes of small scales are therefore useful for e.g. discriminating

Separate universes do not constrain primordial black hole formation

Carr and Hawking showed that the proper size of a spherical overdense region surrounded by a flat FRW universe cannot be arbitrarily large as otherwise the region would close up on itself and become

Primordial black holes as biased tracers

Primordial black holes (PBHs) are theoretical black holes which may be formed during the radiation dominant era and, basically, caused by the gravitational collapse of radiational overdensities. It

Black hole relics and inflation: Limits on blue perturbation spectra.

In the inflationary Universe with the maximum reheating temperature compatible with the observed quadrupole anisotropy, the upper limit is [ital n]=1.4, but it is slightly weaker for lower reheat temperatures, because there may be an extended dustlike phase between the end of inflation and reheating.

Primordial black hole formation

This work is a review of our main results obtained from general relativistic numerical computations of primordial black-hole formation during the radiation-dominated era of the universe. As initial
