Simulating observations of dark matter dominated galaxies: towards the optimal halo profile

de Blok, Willem; Bosma, A; McGaugh, Stacy


Low surface brightness galaxies are dominated by dark matter, and their rotation curves thus reflect their dark matter distribution. Recent high-resolution rotation curves suggest that their dark matter mass-density distributions are dominated by a constant-density core. This seems inconsistent with the predictions of cold dark matter (CDM) models which produce haloes with compact density cusps and steep mass-density profiles. However, the observationally determined mass profiles may be...[Show more]
