The Fornax3D project: overall goals, galaxy sample, MUSE data analysis and initial results

摘要: The Fornax cluster provides a uniquely compact laboratory to study the detailed history of early-type galaxies and role played by environment in driving their evolution transformation from late-type galaxies. Using superb capabilities Multi Unit Spectroscopic Explorer on Very Large Telescope, high-quality integral-field spectroscopic data were obtained for inner regions all bright ($m_B\leq15$) within virial radius Fornax. stellar haloes are also covered out about four effective radii. State-of-the-art dynamical population modelling allows aim particular at better characterising disc components fast-rotating galaxies, constraining radial variations initial-mass functions measuring age, metallicity, $\alpha$-element abundance This paper describes sample selection, observations, overall goals survey, initial results based data, including characterisation kinematics populations large radii; decomposition galaxy directly via orbital structure; ability identify globular clusters planetary nebulae, derivation emission-line diagnostics presence complex ionised gas.
