Internal mass distributions and orbital structures of SAMI passive galaxies
Galaxy mergers play an important role in how galaxies evolve over time, however extragalactic astronomers do not yet completely understand the process by which those mergers happen. The merger history of a galaxy is thought to be one of the major factors that determines the internal kinematic struct...
