WebVoids are believed to have been formed by baryon acoustic oscillations in the Big Bang, collapses of mass followed by implosions of the compressed baryonic matter. Starting from initially small anisotropies from quantum …

Structure Formation with Generalized Dark Matter - IOPscience

WebGalaxies are distributed in long filaments, huge “walls”, and large clusters, which astronomers call the large-scale structure of the cosmos. This structure is a tracer of dark matter, and is a way to understand how the universe has evolved. The 2MASS Redshift Survey (2MRS) is an ambitious map of the galaxies relatively close to the Milky Way.

WebDark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field , which means it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, difficult to detect. WebWe formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics. This framework maps the detailed mi… WebDark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe.
