[astro-ph/0410421] The great disk of Milky-Way satellites an
Posted: October 20 2004
Another interesting paper this week! It seems that our local halo doesn't seem to conform to expectations from cosmology: it's too oblate and has far to few satellites anyway. But I though we do understand "small scale" structure of cosmological kind, i.e. various models to populate DM halos are in agreement with 2dF and SDSS (for example various cell counting exercises, bias from lensing, etc.). So what's wrong with Milky Way?
(Authors do write down a plausible theory in the last section, but nevertheless, our halo is an atypical one!)
