The Many Assembly Histories of Massive Void Galaxies as Revealed by
  Integral Field Spectroscopy
  We present the first detailed integral field spectroscopy study of nine
central void galaxies with M*>10^10 Msun using the Wide Field Spectrograph
(WiFeS) to determine how a range of assembly histories manifest themselves in
the current day Universe. While the majority of these galaxies are evolving
secularly, we find a range of morphologies, merger histories and stellar
population distributions, though similarly low Halpha-derived star formation
rates (<1 Msun/yr). Two of our nine galaxies host AGNs, and two have kinematic
disruptions to their gas that are not seen in their stellar component. Most
massive void galaxies are red and discy, which we attribute to a lack of major
mergers. Some have disturbed morphologies and may be in the process of evolving
to early-type thanks to ongoing minor mergers at present times, likely fed by
tendrils leading off filaments. The diversity in our small galaxy sample,
despite being of similar mass and environment means that these galaxies are
still assembling at present day, with minor mergers playing an important role
in their evolution.
  We compare our sample to a mass and magnitude-matched sample of field
galaxies, using data from the Sydney-AAO Multi-object Integral field
spectrograph (SAMI) galaxy survey. We find that despite environmental
differences, galaxies of mass M*>10^10 Msun have similarly low star formation
rates (<3 Msun/yr). The lack of distinction between the star formation rates of
the void and field environments points to quenching of massive galaxies being a
largely mass-related effect.
