Scientific paper

We investigate the distribution of dark matter (DM) in gas-rich, low-mass
galaxies, confronting them with numerical cosmological simulations with cold
dark matter (LCDM). We show that the derived rotation curves comply best with
cored DM density profiles, whereas the signatures of the central cusps
invariably predicted by LCDM simulations are not seen.
