Primordial Black Holes and Early Cosmology

چکیده
From this we learn that a PBH of initial mass M ∼ 10g will evaporate at the present epoch, while another interesting mass is M ∼ 10g which leads to evaporation around nucleosynthesis. Evaporations of PBHs at these times are strongly constrained. Several mechanisms have been proposed which might lead to PBH formation; the simplest is collapse from large-amplitude, short-wavelength density perturbations. They will form with approximately the horizon mass

Primordial black hole constraints in cosmologies with early matter domination
Moduli fields, a natural prediction of any supergravity and superstring-inspired supersymmetry theory, may lead to a prolonged period of matter domination in the early Universe. This can be observationally viable provided the moduli decay early enough to avoid harming nucleosynthesis. If primordial black holes form, they would be expected to do so before or during this matter dominated era. We ...
متن کاملPrimordial Black Holes as Dark Matter: the Power Spectrum and Evaporation of Early Structures
We consider the possibility that massive primordial black holes are the dominant form of dark matter. Black hole formation generates entropy fluctuations that adds a Poisson noise to the matter power spectrum. We use Ly-α forest observations to constrain this Poisson term in matter power spectrum, then we constrain the mass of black holes to be less than ∼ few × 10 M⊙. We also find that structu...
متن کاملAccretion, Primordial Black Holes and Standard Cosmology
Primordial Black Holes evaporate due to Hawking radiation. We find that the evaporation time of primordial black holes increase when accretion of radiation is included. Thus depending on accretion efficiency more and more number of primordial black holes are existing today, which strengthens the idea that the primordial black holes are the proper candidate for dark matter. PACS numbers : 98.80....
متن کاملPrimordial black holes in braneworld cosmologies: Accretion after formation
We recently studied the formation and evaporation of primordial black holes in a simple braneworld cosmology, namely the Randall-Sundrum type II cosmology. Here we study the effect of accretion from the cosmological background onto the black holes after formation. While it is generally believed that in the standard cosmology such accretion is of negligible importance, we find that during the hi...
متن کاملPrimordial black holes in braneworld cosmologies: Formation, cosmological evolution, and evaporation
We consider the population evolution and evaporation of primordial black holes in the simplest braneworld cosmology: Randall-Sundrum type II. We demonstrate that black holes forming during the high-energy phase of this theory ~where the expansion rate is proportional to the density! have a modified evaporation law, resulting in a longer lifetime and lower temperature at evaporation, while those...
متن کاملMicroscopic Primordial Black Holes and Extra Dimensions
We examine the production and evolution of microscopic black holes in the early universe in the large extra dimensions scenario. We demonstrate that, unlike in the standard four-dimensional cosmology, in large extra dimensions absorption of matter from the primordial plasma by the black holes is significant and can lead to rapid growth of the black hole mass density. This effect can be used to ...
