Descripción
The 31 brightest galaxies (mB ≤ 15 mag) inside the virial
radius of the Fornax cluster were observed from the centres to the
outskirts with the Multi Unit Spectroscopic Explorer on the Very Large
Telescope. These observations provide detailed high-resolution maps of
the line-of-sight kinematics, line strengths of the stars, ionised gas
reaching 2-3 Re for 21 early-type galaxies, and 1-2
Re for 10 late-type galaxies. The majority of the galaxies
are regular rotators, with eight hosting a kinematically distinct core.
Only two galaxies are slow rotators. The mean age, total metallicity,
and [Mg/Fe] abundance ratio in the bright central region inside 0.5
Re and in the galaxy outskirts are presented. Extended
emission-line gas is detected in 13 galaxies, most of them are late-type
objects with wide-spread star formation. The measured structural
properties are analysed in relation to the galaxies' position in the
projected phase space of the cluster. This shows that the Fornax cluster
appears to consist of three main groups of galaxies inside the virial
radius: the old core; a clump of galaxies, which is aligned with the
local large-scale structure and was accreted soon after the formation of
the core; and a group of galaxies that fell in more recently.
