We present the first detailed integral field spectroscopy study of nine central void galaxies with \textrm { M } _ { \star } > 10 ^ { 10 } ~ { } \textrm { M } _ { \odot } 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 H \alpha -derived star formation rates ( < 1 ~ { } \textrm { M } _ { \odot } ~ { } \textrm { yr } ^ { -1 } ) . 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 \textrm { M } _ { \star } > 10 ^ { 10 } ~ { } \textrm { M } _ { \odot } have similarly low star formation rates ( < 3 ~ { } \textrm { M } _ { \odot } ~ { } \textrm { yr } ^ { -1 } ) . 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 .
