The oldest stars in the halo have ages of 12 to 13 billion years, so we estimate that the formation of the Galaxy began about that long ago. (See the chapter on The Big Bang for other evidence that galaxies in general began forming a little more than 13 billion years ago.) Then, ...
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...
They were also not looking for the extremely brilliant rare objects — such as quasars and galaxies with very high rates of star formation — that had been seen up to now. Instead, they concentrated on rather less dramatic, but much more common, galaxies that reionized the Universe and we...

There have been two main types of galaxy formation models to explain all those observations. The first asserts that massive elliptical galaxies formed in a single, rapid collapse of gas and dark matter, during which virtually all the gas was turned quickly into stars. Afterward the galaxies chang...
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 researchers indicate that if both the material ejection and magnetic field phenomena occurred during the early formation of the universe, they would have fundamentally affected the evolution of the first galaxies.
