(2014-10-01)
      We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the Isaac Newton Telescope Photometric Ha Survey of the Northern ...

G.; Sbordone, L.; Worley, C. C. (2014-09)
      Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical ...

    • The Outer Halo of the Nearest Giant Elliptical : A VLT/VIMOS Survey of the Resolved Stellar Populations in Centaurus A to 85 kpc 

      Crnojević, D.; Ferguson, A. M. N.; Irwin, M. J.; Bernard, E. J.; Arimoto, N.; Jablonka, P.; Kobayashi, C. (2013-06-11)
      We present the first deep survey of resolved stellar populations in the remote outer halo of our nearest giant elliptical (gE), Centaurus A (D=3.8 Mpc). Using the VIMOS/VLT optical camera, we obtained deep photometry for ...
