    • Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae 

      Zanatta, Emilio José Bento; Cortesi, Arianna; Chies-Santos, Ana Leonor; Forbes, Duncan Alan; Romanowsky, Aaron J.; Alabi, Adebusola B.; Coccato, Lodovico; Oliveira, Claudia Lucia Mendes de; Brodie, Jean P.; Merrifield, Michael (2018) [Artigo de periódico]
      Recovering the origins of lenticular galaxies can shed light on the understanding of galaxy and compare them with the kinematics of planetary nebulae (PNe). The PNe and GC data come from the Planetary Nebulae Spectrograph ...

    • 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 

      Pulsoni, Claudia; Gerhard, Ortwin; Arnaboldi, Magda; Coccato, Lodovico; Longobardi, Alessia; Napolitano, Nicola R.; Moylan, Emily K. M.; Narayan, Chaitra A.; Gupta, V.; Burkert, Andreas; Capaccioli, M.; Chies-Santos, Ana Leonor; Cortesi, Arianna; Freeman, Kenneth C.; Kuijken, Koenraad H.; Merrifield, Michael; Romanowsky, Aaron J.; Tortora, Crescenzo (2018) [Artigo de periódico]
      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 SLUGGS survey : chromodynamical modelling of the lenticular galaxy NGC 1023 

      Cortesi, Arianna; Chies-Santos, Ana Leonor; Pota, Vincenzo; Foster, Caroline; Coccato, Lodovico; Oliveira, Claudia Lucia Mendes de; Forbes, Duncan Alan; Merrifield, Michael; Bamford, Steven Peter; Romanowsky, Aaron J.; Brodie, Jean P.; Kartha, Sreeja S.; Alabi, Adebusola B.; Proctor, Robert Neil; Almeida, Andres (2016) [Artigo de periódico]
      Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper, we present a new catalogue of GC velocities ...
