Abstract

We present preliminary kinematic results from our VLT programme of spectroscopic observations in the Carina dwarf spheroidal galaxy using the FLAMES multi-object spectrograph. These new data suggest that the dark matter halo of this galaxy has a uniform density core. The implications for our understanding of the nature of the dark matter are discussed.
