  • Observations of a cosmic web filament have been made in Lyman-α emission; the filament has a projected size of approximately 460 physical kiloparsecs, and its estimated cold gas mass is more than ten times larger than what is typically found in cosmological simulations.

  • The baryon density determined along the lines of sight to localized fast radio bursts is consistent with that determined from the cosmic microwave background and required by Big Bang nucleosynthesis.

  • A two-dimensional spectroscopic investigation of a large, luminous filament of the cosmic web near QSO UM287 reveals that the brightest emission region is an extended rotating hydrogen disk with a velocity profile that is characteristic of gas in a 1013-solar-mass dark-matter halo, with a geometry that is strongly suggestive of cold flow accretion.
