Scientific paper

We present photometric and kinematic results obtained by measuring 197 PNe discovered in the flattened Fornax elliptical galaxy NGC 1344. We build the PN luminosity function (PNLF), which gives a distance modulus m - M = 31.4+/-0.2. From the radial velocities we obtain the line-of-sight velocity dispersion, which indicates the presence of a dark matter halo around this galaxy.
