The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey: the kinematic diversity of stellar halos and the relation between halo transition scale and stellar mass

The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey: the kinematic diversity of stellar halos and the relation between halo transition scale and stellar mass

Context. In the hierarchical two-phase formation scenario, the halos of early type galaxies (ETGs) are expected to have different physical properties from the galaxies’ central regions. Aims. The ePN.S survey characterizes the kinematic properties of ETG halos using planetary nebulae (PNe) as trace...
