I don’t think this one does help — the authors had to more or less
retract their claim of detecting a black hole in the center of M15, I believe.

[[Mod.note -- Looking at the STSCI press release, I was pleased to see
that they actually have a prominent section "Alternative Scientific
Interpretations of the data:" with links to 3 astro-ph preprints
(alas their link for the 2nd one mistakenly gives the 1st's number):
astro-ph/0210158 (Gerssen, van der Marel, et al.)

astro-ph/0210133 (Baumgardt et al.)

    You’re probably right, but that’s not what I got from the presentation on
    "Black Holes in Globular Clusters and Galaxies" at STSI Spring Symposium last
    week.  Please don’t get the wrong impression.  My brother-in-law is the
    scientist.  I was just an ignorant bystander, fortunate to attend with him.

    Below are links to Karl Gebhardt (University of Texas), and an audio file
    lecture by him on the "Status on the Observational Evidence for Black Holes in
    Globular Clusters".  Worth a listen, if you have a few minutes.
