We present results showing an improvement of the accuracy of perturbation theory as applied to cosmological structure formation for a useful range of quasi-linear scales. The Lagrangian theory of gravitational instability of an Einstein-de Sitter dust cosmogony investigated and solved up to the third order in the series of papers, is compared with numerical simulations. In this paper we study t...

In a hierarchical cosmogony galaxies build up by continuous merging of smaller structures. At redshift three the matter content of a typical present-day galaxy is dispersed over several individual clumps embedded in sheet-like structures, often aligned along filaments. We have used hydrodynamical simulations to investigate the spatial distribution and absorption properties of metal enriched gas...

It may be agreed by most people that the growth of each person or country is driven by the power of gender. However, human’s understanding of gender origin is very little, and is solely based on the phenomenon of life on Earth. If humans raise up their head and look at the universe, its preliminary answer may emerge. In the history of mankind, the first person who was surprised at the look of c...

We use a semianalytic galaxy catalogue constructed from the Millennium Simulation (MS) to study the satellites of isolated galaxies in the ΛCDM cosmogony. The large volume surveyed by the MS (500 hMpc), together with its unprecedented numerical resolution, enable the compilation of a large sample of ∼ 80, 000 bright (Mr < −20.5) primaries, surrounded by ∼ 178, 000 satellites down to the faint m...

Robert Alter 4. As many modern commentators have noted, the first Creation account concludes with the summarizing phrase in the first half of this verse: " This is the tale [literally, these are the begettings] of the heavens and the earth when they were created," these two paired terms, "heavens" and "earth," taking us back in an envelope structure to the paired terms of the very first verse o...

We present results of N-body/gasdynamical simulations designed to investigate the evolution of X-ray clusters in a flat, low-density, Λ-dominated cold dark matter (CDM) cosmogony. The simulations include self-gravity, pressure gradients and hydrodynamical shocks, but neglect radiative cooling. The density profile of the dark matter component can be fitted accurately by the simple formula origin...

This article develops and employs modern methods for mathematical modeling. In particular, the methods of nonstandard analysis are applied to general language logic-systems. This allows the operators for the only known mathematical cosmogony, the General Grand Unification Model (GGU-model), to more clearly exhibit their hyper-logical properties. All of the GGU-model entities and processes are p...

EVER since he took the first steps towards a conscious life, Man has tried to solve the problems of cosmogony. The most complicated and also the most interesting of these is that of the origin of life. At different times and at different stages of culture different answers have been given. The religious teachings of all ages and peoples have usually attributed the appearance of life to some cre...

Modem science prides itself in being concerned only with the rational and the useful; it mistrusts the uncontrolled imagination and is disdainful of the fairy tales in which our ancestors rejoiced. This haughty attitude, however, is of recent date. In its youth, science expressed itself in art and poetry and knew the intoxication of magic. Only after it had reached adulthood and had to pay the ...
