The mass profile of NGC 3377 from a Bayesian approach
  The mass profile for the moderately bright elliptical NGC 3377 is studied
through an spherical Jeans analysis, combined with a Bayesian approach. The
prior distributions are generated from dark matter simulations and
observational constraints. The observational data set consist of Gemini/GMOS
long-slit observations aligned with the major and minor axes of the galaxy, and
are supplemented with data from the literature for the diffuse stellar
component, globular clusters and planetary nebulae. Although the galaxy is
assumed to alternatively reside in central and satellite haloes, the comparison
with literature results prefer the latter option. Several options of constant
anisotropy are considered, as well as both NFW and Einasto mass profiles. The
analysis points to an intermediate mass halo, presenting a virial mass around
$(3.6\pm0.6)\times 10^{11}\,{\rm M_{\odot}}$.
