    • 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 ...

    • Morphology of AGN emission-line regions in SDSS-IV MaNGA survey 

      He, Zhicheng; Sun, Ai-Lei; Zakamska, Nadia L.; Wylezalek, Dominika; Kelly, Michael; Greene, Jenny E.; Rembold, Sandro Barboza; Riffel, Rogério; Riffel, Rogemar André (2018) [Artigo de periódico]
      Extended narrow-line regions (NLRs) around active galactic nuclei (AGN) are shaped by the distribution of gas in the host galaxy and by the geometry of the circumnuclear obscuration, and thus they can be used to test the ...

    • SDSS-IV MaNGA : environmental dependence of stellar age and metallicity gradients in nearby galaxies 

      Zheng, Zheng; Wang, Huiyuan; Ge, Junqiang; Mao, Shude; Li, Cheng; Li, Ran; Mo, Houjun; Goddard, Daniel; Bundy, Kevin; Li, Hongyu; Nair, Preethi B.; Lin, Lihwai; Long, Richard J.; Riffel, Rogério; Thomas, D.; Masters, K.L.; Bizyaev, D.; Brownstein, Joel R.; Zhang, Kai; Law, David R.; Drory, Niv; Lopes, Alexandre Roman; Malanushenko, E. (2017) [Artigo de periódico]
      We present a study on the stellar age and metallicity distributions for 1105 galaxies using the STARLIGHT software on MaNGA (Mapping Nearby Galaxies at APO) integral field spectra.We derive age and metallicity gradients ...
