Webhierarchical Universe A cosmological model, originally due to Charlier in 1908, in which inhomogeneities exist on increasingly larger scales: galaxies occur in clusters (as observed), which in turn are clustered into superclusters (as observed), which may in turn aggregate as clusters of superclusters, and so on. Webtic model of the data, so it is hard to ask how “good” a clustering is, to compare to other models, to make predictions and cluster new data into an existing hier-archy. We use statistical inference to overcome these limitations.

In physical cosmology, structure formation is the formation of galaxies, galaxy clusters and larger structures from small early density fluctuations. The universe, as is now known from observations of the cosmic microwave background radiation, began in a hot, dense, nearly uniform state approximately 13.8 billion years ago. However, looking at the night sky today, structures on all scales can be seen, from stars and planets to galaxies. On even larger scales, galaxy clusters and s… Web2 de out. de 2024 · The most obvious and uncontroversial class of structures beyond the galaxy is the galaxy group or cluster.
