An Oxford-led team identifies a giant, razor-thin cosmic filament about 140 million light-years away that is rotating with galaxies aligned to its spin, offering new insights into how galaxies acquire angular momentum and evolve. The finding, enabled by MeerKAT’s MIGHTEE survey and complemented by DESI and SDSS data, challenges existing models of galaxy formation within the cosmic web.
Astronomers have discovered one of the largest rotating structures in the universe, a cosmic filament about 140 million light years away, composed of a thin chain of hydrogen-rich galaxies that appear to rotate collectively, providing new insights into galaxy formation and the dynamics of the cosmic web.
Astronomers have captured the first direct image of a cosmic filament connecting distant galaxies, providing crucial evidence for the cosmic web's role in galaxy formation and dark matter distribution, using advanced telescopic technology. This breakthrough enhances our understanding of the universe's large-scale structure and paves the way for future research with next-generation instruments.
A team of European scientists has improved the quantification of the warm-hot intergalactic medium (WHIM) and cosmic filaments using data from the eROSITA X-ray instrument. These cosmic filaments, which are vast structures of hot, diffuse gas, contain about 50% of the universe's baryonic mass. The study, published in Astronomy & Astrophysics, involved analyzing X-ray emissions from nearly 8,000 filaments to determine their temperature and baryon density contrast. The findings align with numerical simulations and are expected to enhance understanding of the WHIM as future X-ray missions explore its properties further.
