For a sense of perspective, a comparative extreme structure (of a galaxy pair and dark matter halo) in the present-day universe would have the mass of about 10,000 trillion suns.

This theory predicts that the distribution of substructures within dark matter halos like the Milky Way should be isotropic, which does not match the observations [1], showing that the distribution of these objects is completely anisotropic.

If the results hold, scientists will have to reconsider what sort of shape that dark matter halo takes, although it's unlikely to cause any major cosmological upheavals.

Zheng said that they can't see the dark matter halo, but its gravity acts on the star, asserting that they gain insight from the star's trajectory and velocity, which are affected by gravity from different parts of Milky Way.
At least one team has found evidence for a WIMP-wind--or seasonal fluctuation in dark matter particles, the product of Earth's orbit carrying it through the galactic dark matter halo. But those reports are inconsistent with other experiments' negative results, and the WIMP sightings to date have been less than definitive, leaving scientists puzzled.
Topics include the cosmic microwave background, including the halo mass function in the dark ages, cosmic microwave background challenges to the standard model, and the role of the local void; those on cosmic dawn include redshift quasars and the Subaru telescope; those on large scale structure consider redshift-space distortions and dark energy; a number of papers describe galaxy formation and evolution, including those on age-dating the red sequence in low-redshift clusters; those on AGN evolution include the connection between black hole mass and dark matter halo mass; those on feedback and environment include constraining feedback in galaxy formation and mass and the morphology-density relation; and those on galaxy evolution and the environment include a survey.
