I can't claim to be providing certainly accurate information on this, since it's been a while since I've done relevant physics reading (lay books, not academic), but in the early universe (before inflation went out of control) there were irregularities that gave rise to clumping, from which the first stars and galaxies originated.

Decades earlier, cosmologists looking at Einstein's equations determined three possible destinies lying in wait for the universe, depending on how much stuff — galaxies, stars, humans — it contained.

After 2006's WMAP announcement cosmologists pushed the Hubble Space Telescope to its observational limits, conducting several deep surveys in search of the early star - forming galaxies required to support the result.

An earlier study found 27 dwarf galaxies, 15 arranged in a narrow plane.

Many other potential applications of this dataset are explored in the series of papers, and they include studying the role of faint galaxies during cosmic reionisation (starting just 380,000 years after the Big Bang), galaxy merger rates when the Universe was young, galactic winds, star formation as well as mapping the motions of stars in the early Universe.

Earlier research with NASA's Chandra X-ray observatory revealed that the jets from this AGN are carving out a pair of giant «radio bubbles,» huge cavities in the hot, diffuse plasma that surrounds the galaxy.

Earlier studies had suggested that the gravity of nearby stars would have ripped apart these primordial clumps, but the new simulations show that this would only happen in the crowded core of galaxies, leaving the clumps in the galactic suburbs intact (arxiv.org/abs/1006.3392).

In the early universe, astronomers believe, dark matter provided the gravitational scaffolding on which ordinary matter coalesced and grew into galaxies.

The galaxies in the early universe started off small and the theory of the astronomers is that the baby galaxies gradually grew larger and more massive by constantly colliding with neighbouring galaxies to form new, larger galaxies.
