A Milky Way “Seed” Discovered? — 1 Comment

  1. Nature Article:
    An intermediate-mass black hole in the centre of the globular cluster 47 Tucana
    by: Bülent Kiziltan, Holger Baumgardt & Abraham Loeb

    globular cluster 47 Tucana centre
    contains 2200 solar mass 4.4E+36 gram
    within 4*pi/3*(1 parsec)^3 or 1.2E+56 cubic cm
    for a density of 3.6E-20 gram/cubic cm

    This low density does not seem indicative of a black hole.
    Since this central region is reported to be electromagnetically invisible,
    could it be in the form of dark matter?
