Abstract:
We present the results of a radial velocity survey of planetary
nebulae (PNs) in the normal elliptical galaxy NGC 3379 performed with
the Kitt Peak 4m telescope and the NESSIE multifiber spectrograph. In
two half-nights, we measured 29 PNs with projected galactocentric
distances between 0.4 and 3.8 effective radii (1<R<10kpc) with an
observational uncertainty of ∼7km/s. These data extend 3 times
further into the halo than any previous absorption-line velocity
study. The velocity dispersion and photometric profile of the galaxy
agrees extremely well with that expected from a constant mass-to-light
ratio, isotropic orbit Jaffe model with M/LB∼7; the best-fitting
anisotropic models from a quadratic programming algorithm also give
M/LB∼7. The data are consistent with models that contain no dark
matter within 3.5 effective radii of the galaxy's nucleus.
