  2. Galaxy filament - Wikipedia

    en.wikipedia.org/wiki/Galaxy_filament

    In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...

    en.wikipedia.org/wiki/Observable_universe

    In 2021, an international team, headed by Roland Bacon from the Centre de Recherche Astrophysique de Lyon (France), reported the first observation of diffuse extended Lyman-alpha emission from redshift 3.1 to 4.5 that traced several cosmic web filaments on scales of 2.5−4 cMpc (comoving mega-parsecs), in filamentary environments outside ...

  4. List of largest cosmic structures - Wikipedia

    en.wikipedia.org/wiki/List_of_largest_cosmic...

    This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.

    Astronomers studying the site of a supernova seen 843 years ago have captured an image of the strange filaments left behind by the stellar explosion.

  6. Fuzzy cold dark matter - Wikipedia

    en.wikipedia.org/wiki/Fuzzy_cold_dark_matter

    The wave behavior leads to interference patterns, spherical soliton cores in dark matter halo centers, [2] and cylindrical soliton-like cores in dark matter cosmic web filaments. [3] Fuzzy cold dark matter is a limit of scalar field dark matter without self-interaction. [4] [5] It is governed by the Schrödinger–Poisson equation.

  7. Void (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Void_(astronomy)

    Regions of higher density collapsed more rapidly under gravity, eventually resulting in the large-scale, foam-like structure or "cosmic web" of voids and galaxy filaments seen today. Voids located in high-density environments are smaller than voids situated in low-density spaces of the universe. [3]

    This“cosmic web” started out tenuous and became more distinct over time as gravity drew matter together. Astronomers for the ASPIRE program using the NASA/ESA/CSA James Webb Space Telescope have discovered a thread-like arrangement of 10 galaxies that existed just 830 million years after the Big Bang.

    An MeerKAT image of the Galactic Center showing a number of filaments Radio image of a number of parallel filaments in the Galactic Center; Sagittarius A*, the Milky Way's central black hole, is located in the bright region in the bottom right [1] [2] Nonthermal radio filaments from the 4'' resolution MeerKAT mosaic; oriented vertically for space; scales given assuming a distance of 8.2 kpc
