    • A Megacam Survey of Outer Halo Satellites. VI. The Spatially resolved Starformation History of the Carina ... 
      Santana Rojas, Felipe; Muñoz Vidal, Ricardo Rodrigo; de Boer, T. J. L.; Simon, Joshua D.; Geha, Marla; Coté, Patrick; Guzmán Fernández, Andrés; Stetson, Peter B.; Djorgovski, S. George (IOP, 2016)
      We present the spatially resolved star-formation history (SFH) of the Carina dwarf spheroidal galaxy, obtained from deep, wide-field g and r imaging and a metallicity distribution from the literature. Our photometry covers ...
    • The Gaia -ESO Survey: Age spread in the star forming region NGC 6530 from the HR diagram and gravity indicators 
      Prisinzano, L.; Damiani, F.; Kalari, V.; Jeffries, R.; Bonito, R.; Micela, G.; Wright, N. J.; Jackson, R. J.; Tognelli, E.; Guarcello, M. G.; Vink, J. S.; Klutsch, A.; Jiménez-Esteban, F. M.; Roccatagliata, V.; Tautvaišiene, G.; Gilmore, G.; Randich, S.; Alfaro, E. J.; Fla (EDP Sciences, 2019)
      Context. In very young clusters, stellar age distribution is empirical proof of the duration of star cluster formation and thus it gives indications of the physical mechanisms involved in the star formation process. ...
    • The magellanic bridge cluster NGC 796: deep optical AO imaging reveals the stellar content and initial mass ... 
      Kalari, Venu M.; Carraro, Giovanni; Evans, Christopher J.; Rubio López, Mónica (IOP Publishing Ltd, 2018)
      NGC 796 is a massive young cluster located 59 kpc from us in the diffuse intergalactic medium of the 1/5-1/10 Z(circle dot) Magellanic Bridge, allowing us to probe variations in star formation and stellar evolution processes ...
    • The thickening of the thin disk in the third Galactic quadrant 
      Carraro, Giovanni; Vázquez, Rubén; Costa Hechenleitner, Edgardo; Ahumada, Javier; Giorgi, Edgar (IOP Publishing, 2015)
      In the third Galactic quadrant (180 degrees <= l <= 270 degrees) of the Milky Way, the Galactic thin disk exhibits a significant warp-shown both by gas and young stars-bending down a few kiloparsecs below the formal Galactic ...
