Dark Matter and the Value of Ωgalaxy clusters. Taken at face value, these two methods give contadictory results, Ω = 1 in the first case, and Ω ≤ 0.5 in the second. These results can be reconciled if, either Ω = 1 and the standard nucleosynthesis constraints are incorrect,or Ω ≃ 0.4 and galaxies are substantially less clustered than the dark mass.

Lectures on Inflationary Cosmologyty and temperature. With the rapid expansion of the Universe the average energy of particles, given by the temperature, decreased rapidly, and the Universe became cold. This theory became especially popular after the discovery of the microwave background radiation. However, by the end of the 70’s it

BRIEF

Back Reaction of Strings in Self Consistent String Cosmologyd D-dimensional universes are treated for any expansion factor R. Strings obey the perfect fluid relation p = (γ - 1)p with three different behaviours: (i) Unstable for R → ∞ with growing energy density ρ ~ R., . pressure, and γ = (D - 2)/(D - 1) for inflationary universes; (ii) Dual for R → 0, with

Cosmological Inflation, Microwave Background Anisotropies and Large Scale Structure of the Universe-Jacobi methods, I will describe . how to compute density fluctuations and cosmic microwave anisotropies arising from inflation, and . improvements of the Zel’dovich approximation describing gravitational collapse. I compare these results with the latest cosmological observations.

The Big Bang and the Infrared Sky as Seen by Cobehe early universe. It also measured emission from nearby sources such as the stars, dust, molecules, atoms, ions, and electrons in the Milky Way, and dust and comets in the Solar System. It was launched 18 November 1989 on a Delta rocket, carrying one microwave instrument and two cryogenically coole
