    Orbital decomposition of the nuclear regions in the early-type galaxy FCC 47: Unveiling the nuclear cluster origin
    Context. Nuclear star clusters (NSCs) are among the densest stellar systems in the Universe and often coexist with supermassive black holes (SMBHs) at galaxy...

    Origin of E+A galaxies - I. Physical properties of E+A galaxies formed from galaxy merging and interaction
    We investigate the structural, kinematical and spectrophotometric properties of `E+A' galaxies - those with strong Balmer absorption lines but no significant...

    Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
    Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II)...
