Astronomers using the FAST radio telescope traced a nearly four-light-year-long, linear filament of galaxies in the Ursa Major Supergroup, providing direct observational evidence of a delicate cosmic web strand dominated by dark matter that guides gas flows and galaxy formation across the universe.
Researchers have developed a new method to measure the mass of cosmic filaments, which connect galaxy clusters and form the cosmic web, potentially unlocking secrets about dark matter and dark energy. By analyzing the redshift dispersion of galaxies within these filaments, scientists can estimate the hidden dark matter mass. This method, tested in cosmological simulations, could provide insights into the universe's structure and evolution when applied to real galaxy surveys.
