      The Magellanic System represents one of the best places to study the formation and evolution of galaxies. Photometric surveys of various depths, areas and wavelengths have had a significant impact on our understanding of ...

    • The VMC survey - IX : Pilot study of the proper motion of stellar populations in the LMC from 2MASS and VISTA data 

      Cioni, M-R.L.; Giradi, L.; Moretti, M.I.; Piffl, T.; Ripepi, V.; Rubele, S.; Scholz, R.D.; Bekki, K.; Clementini, G.; Ivanov, V.D.; Oliveira, J.M.; van Loon, J. Th (2014-02)
      Proper motion (PM) studies are fundamental ingredients in the understanding of the orbital history of galaxies. Current measurements do not yet provide a satisfactory answer to the possible scenarios for the formation and ...

    • The VMC survey - V : First results for classical Cepheids

      The VISTA Magellanic Cloud (VMC; PI: M.-R. L. Cioni) survey is collecting deep Ks-band time series photometry of the pulsating variable stars hosted by the system formed by the two Magellanic Clouds (MCs) and the bridge ...

    • The VMC survey - VII : Reddening map of the 30 Doradus field and the structure of the cold interstellar medium 

      Tatton, B.; van Loon, J. Th; Cioni, M-R.L.; Clementini, G.; Emerson, J.P.; Girardi, L.; de Grijs, R.; Groenewegen, M.A.T.; Gullieuszik, M.; Ivanov, V.D.; Moretti, M.I.; Ripepi, V.; Rubele, S. (2013-06)
      The details of how galaxies have evolved over cosmological times are imprinted in their star formation history, chemical enrichment and morpho-kinematic structure. Parameters behind these, such as effective temperature and ...
