Reuben Lim,David Mba,Emmanuel O. Ezugwuications of the recent evidence for the presence of Massive Compact Halo Objects (MACHOS) in the halo of our galaxy. Within the current observational uncertainties, the fraction of MACHOs can be as high as 100% of the halo or as low as 10%. We argue that the “natural” conclusion that they form the t

Covariant Analysis of Dynamics and of CBR Anisotropy gauge-invariant approach to Cosmic Background Radiation (‘CBR’) anisotropies — the Sachs-Wolfe (‘SW’) effect (including the so-called ‘integrated SW-effect’). In the first part we emphasize the differences between the results of the full covariant dynamic theory and (a) linearised theory in ‘almost

Reheating in Inflationary Cosmologyse after inflation [1]. It makes this process extremely important. However, for many years the theory of reheating remained the least developed part of inflationary theory. Even now, when many features of the mechanism of reheating are understood, the literature on this subject is still full of cont

Out of Equilibrium Fields in Inflationary Dynamics. Density Fluctuationsnergy densities involved (∼1/g ∼ 10.) make necessary the use of non-perturbative approaches as the large . and Hartree methods. We start these lectures by introducing the such non-perturbative out of equilibrium methods in cosmological universes. We discuss the renormalization procedure and the choi

For a realistic scalar mass .. GeV the transition to the high temperature regime is described by a crossover, due to the strong electroweak gauge interactions

Mapping these CMB anisotropies precisely will provide decisive and extraordinarily exciting measurements of the geometry, constitution, and early history of the universe. Future CMB anisotropy observations allow a stringent test of cosmolo

The Cosmic Microwave Backgroundrvations are interpreted, the recent rapid observational progress on anisotropies of the microwave background is described, together with the improvements that can be expected in the near future. This data is then used to set some preliminary constraints on the values of the fundamental cosmological
