Thermal Hawking emission from black holes is a remarkable consequence of the unification of quantum physics and gravitation. Black holes of a few solar masses are the only ones which can form in the present universe. However, having temperatures million times smaller than the ambient cosmic background radiation they cannot evaporate. Primordial black holes of M ∼ 1014g would evaporate over a Hubble age and considerable ongoing effort is on to detect such explosions. I point out, however, that… 
The Evolution of Primordial Black Hole Masses in the Radiation-Dominated Era
We discuss in this work the behaviour of primordial black holes (PBHs) in the radiation era. Taking into account the Hawking evaporation and the absorption of energy we revisit the complete
Extremal charged black holes, dark matter and dark energy
Formation of black holes may be constrained by intrinsic parameters characterizing them such as electric charge. Here we discuss the effects of a relatively minute excess of charge on extremal black
Primordial black holes in phantom cosmology
We investigate the effects of accretion of phantom energy onto primordial black holes. Since Hawking radiation and phantom energy accretion contribute to a decrease of the mass of the black hole, the
Thermal Gravitational Waves from Primordial Black Holes
Thermal gravitational waves can be generated in various sources such as, in the cores of stars, white dwarfs and neutron stars due to the fermion collisions in the dense degenerate Fermi gas (1-3).
Primordial black holes as heat sources for living systems with longest possible lifetimes
Just forty years ago, Hawking wrote his famous paper on primordial black holes (PBH). There have been since innumerable discussions on the consequences of the existence of such exotic objects and
On the variably-charged black holes in general relativity: Hawking's radiation and naked singularities
In this paper variably-charged non-rotating Reissner–Nordstrom and rotating Kerr–Newman black holes are discussed. Such a variable charge e with respect to the polar coordinate r in the field
Some unique constants associated with extremal black holes
In recent papers we had developed a unified picture of black hole entropy and curvature which was shown to lead to Hawking radiation. It was shown that for any black hole mass, holography implies a
Hawking temperature: an elementary approach based on Newtonian mechanics and quantum theory
In 1974, the British physicist Stephen Hawking discovered that black holes have a characteristic temperature and are therefore capable of emitting radiation. Given the scientific importance of this
Ultrarelativistic Bondi–Hoyle accretion – I. Axisymmetry
An ultrarelativistic relativistic study of axisymmetric Bondi--Hoyle accretion onto a moving Kerr black hole is presented. The equations of general relativistic hydrodynamics are solved using high
Numerical analysis of the ultrarelativistic and magnetized Bondi--Hoyle problem
In this thesis, we present numerical studies of models for the accretion of fluids and magnetofluids onto rotating black holes. Specifically, we study three main scenarios, two of which treat


Some cosmological consequences of primordial black-hole evaporations
According to Hawking, primordial black holes of less than 10/sup 15/ g would have evaporated by now. This paper examines the way in which small primordial black holes could thereby have contributed
Black hole explosions?
QUANTUM gravitational effects are usually ignored in calculations of the formation and evolution of black holes. The justification for this is that the radius of curvature of space-time outside the
Gamma rays from primordial black holes
This paper examines the possibilities of detecting hard ..gamma..-rays produced by the quantum-mechanical decay of small black holes created by inhomogeneities in the early universe. Observations of
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

The emission produced over the lifetime of black holes with masses less than M*≃4-6×10 14 g is investigated by convolving the Hawking emission formulas with a Monte Carlo QCD jet code and shows little sensitivity to the uncertainties in particle-physics models.
A better way of searching for black-hole explosions?
BLACK holes of ≲ 1015 g evaporate in ∼ 1010 yr, and eventually annihiliate into a burst of energetic photons and particles1. To test this theoretical prediction would be extraordinarily significant
Primordial black holes and primordial nucleosynthesis: Effects of hadron injection from low mass holes
We investigate the influence of hadron injection from evaporating primordial black holes (PBHs) in the early stage of the primordial nucleosynthesis era (t = 10^{-3} - 10^4 sec). The emitted
Particle creation by black holes
AbstractIn the classical theory black holes can only absorb and not emit particles. However it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were
The present equilibrium formulation of thermodynamics for black holes has several drawbacks, such as assuming the same temperature for black hole and heat bath. Recently the author formulated
Recently attempts have been made to link vacuum zero-point fields (ZPF), with a nonzero cosmological constant (Λ), which is now treated as a cosmological free variable to be determined by
