Richard Massey, Liliya Williams, 20 others: The behaviour of dark matter associated with 4 bright cluster galaxies in the 10 kpc core of Abell 3827, MNRAS (2014?) 15 pages now finds fairly direct evidence dark matter does interact with other dark matter particles (which, if so, I have previously argued here, but they do not argue, must be due to a new "dark force") with a cross-section (they claim) of (1.7 +- 0.7) * 10^(-4) cm^2/gram. The previous paper had claimed an upper bound of 0.47 cm^2/gram. -- Warren D. Smith http://RangeVoting.org <-- add your endorsement (by clicking "endorse" as 1st step)
