galaxies/ galaxyformationtheorylarge-scale structurecold dark matterclusteringmodelThe basic framework for a successful theory of large-scale structure is provided by the cold dark matter hypothesis. It works surprisingly well, and has led to predictions, such as the clustering of gas and galaxies as...
We present N-body simulations of groups of galaxies with a number of very different initial conditions. These include spherical isotropic, nonspherical anisotropic collapses and virialised spherical systems. In all cases but one the merging instability leads to the formation of a giant central galaxy...
formation occurs most rapidly in the spiral arms, where the density of interstellar matter is highest. The Galaxy captured (and still is capturing) additional stars and globular clusters from small galaxies that ventured too close to the Milky Way. In 3 to 4 billion years, the Galaxy will ...
Those who criticise the notion of Indigenous science will arguet hat culture is irrelevant to science, that the behaviour of atoms or the formation of galaxies is not based on culture.But the rules that govern nature are distinct from the process by which we come to learn about them.That is...
The symposium Environment and the Formation of Galaxies: 30 years later, was organised with the purpose of establishing the environmental impact on the evolution of galaxies and its dependence on look-back time. Special emphasis was placed on the physical mechanisms that are responsible for ...

Nature's series of review articles on astronomy, marking the International Year of Astronomy 2009, continues with a look at the 'final frontier' in observational astronomy: the formation of the first stars, galaxies and massive black holes. At present th
(A) the space between the galaxies is devoid of matter (B) the space between galaxies is occupied by stars that cannot be detected by optical photographs (C) galaxies have decreased in mass by half since their formation (D) galaxies contain stars, each the size of Jupiter, which form clus...
The prevalence, orientation, and inferred masses of these submillimetre companion galaxies suggest that we are witnessing the synchronous formation of the most luminous elliptical galaxies found today at the centres of rich clusters of galaxies. 展开 ...
