Cosmology

Definition

Cosmology is the study of the universe; its birth, evolution, and ultimate fate. This includes further developing and refining the prevailing model, the Big Bang theory, investigating the universe’s rate of expansion, and measuring radiation left over from the Big Bang, the so-called cosmic microwave background.

    When the Universe was just 3 billion years old, half of the most massive galaxies had already ceased star formation, and such a galaxy has now been observed using gravitational lensing, unexpectedly turning out to be a compact, fast-spinning disk galaxy rather than a proto-bulge galaxy.

    The brightest galaxy in a cluster is known to align with its host filament in the local Universe. Here this correlation is extended to when the Universe was just a third of its current age. With this, the privileged history of brightest cluster galaxies is reinforced.

    Coevolving millions of cold dark matter particles and neutrinos within one N-body simulation, TianNu, shows that regions of similar dark matter density can have different neutrino densities. These density variations may have an effect on the cosmic structure.
