    • A catalogue of infrared star clusters and stellar groups 

      Bica, Eduardo Luiz Damiani; Dutra, Carlos Maximiliano; Barbuy, Beatriz (2003) [Journal article]
      We compiled a catalogue of infrared star clusters in the Galaxy, which are most of them embedded. It condenses the growing literature information. We also include in the sample infrared stellar groups which are less dense ...

    • Mortality and dust expulsion in early phases of stellar clusters : evidence from NIR photometry of nearby, spiral galaxies 

      Grosbol, Preben; Dottori, Horacio Alberto (2013) [Journal article]
      Context. It is often argued that young stellar clusters suffer a significant infant mortality that is partly related to the expulsion of dust and gas in their early phases caused by radiation pressure from hot stars and ...

    • Near-infrared integrated spectra of Galactic globular clusters : testing simple stellar population models 

      Riffel, Rogério; Dutra, Daniel Ruschel; Pastoriza, Miriani Griselda; Rodriguez-Ardila, Alberto; Santos Junior, Joao Francisco Coelho dos; Bonatto, Charles Jose; Ducati, Jorge Ricardo (2011) [Journal article]
      We present SOAR/OSIRIS cross-dispersed near-infrared (NIR) integrated spectra of 12 Galactic globular clusters that are employed to test Maraston NIR evolutionary population synthesis models, and to provide spectral ...

    • New Galactic star clusters discovered in the VVV survey 

      Borissova, Jura; Bonatto, Charles Jose; Kurtev, Radostin Georgiev; Clarke, J. R. A.; Peñaloza, Francisco; Sale, Stuart E.; Minniti, Dante; Alonso Garcia, Javier; Artigau, Étienne; Barbá, Rodolfo H.; Bica, Eduardo Luiz Damiani; Baume, Gustavo Luis; Catelan, Márcio; Chené, André-Nicolas; Dias, Bruno Moreira de Souza; Folkes, S. L.; Froebrich, Dirk; Geisler, Doug; Grijs, Richard de; Hanson, M. M.; Hempel, Maren; Ivanov, Valentin D.; Kumar, M. S. N.; Lucas, Philip W.; Mauro, Francesco; Moni Bidin, Christian; Rejkuba, Marina; Saito, Roberto K.; Tamura, Motohide; Toledo, Ignacio (2011) [Journal article]
      Context. VISTA Variables in the Vía Láctea (VVV) is one of the six ESO Public Surveys operating on the new 4-m Visible and Infrared Survey Telescope for Astronomy (VISTA). VVV is scanning the Milky Way bulge and an adjacent ...

    • New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge 

      Borissova, Jura; Chené, André-Nicolas; Ramírez Alegría, Sebastián; Sharma, S.; Clarke, J. R. A.; Kurtev, Radostin Georgiev; Negueruela, Ignacio; Marco Tobarra, Amparo; Amigo, Pia; Minniti, Dante; Bica, Eduardo Luiz Damiani; Bonatto, Charles Jose; Catelan, Márcio; Fierro, C.; Geisler, Doug; Gromadzki, Mariusz; Hempel, Maren; Hanson, M. M.; Ivanov, Valentin D.; Lucas, Philip W.; Majaess, Daniel J.; Moni Bidin, Christian; Popescu, Bogdan; Saito, Roberto K. (2014) [Journal article]
      Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent ...

    • New infrared star clusters in the Northern and Equatorial Milky Way with 2MASS 

      Bica, Eduardo Luiz Damiani; Dutra, Carlos Maximiliano; Soares, Jules Batista; Barbuy, Beatriz (2003) [Journal article]
      We carried out a survey of infrared star clusters and stellar groups on the 2MASS J, H and Ks all-sky release Atlas in the Northern and Equatorial Milky Way (350◦ < < 360◦, 0◦ < < 230◦). The search in this zone complements ...

    • New infrared star clusters in the southern Milky Way with 2MASS 

      Dutra, Carlos Maximiliano; Bica, Eduardo Luiz Damiani; Soares, Jules Batista; Barbuy, Beatriz (2003) [Journal article]
      We carried out a 2MASS J, H and Ks survey of infrared star clusters in the Milky Way sector 230º < l < 350º . This zone was the least studied in the literature, previously including only 12 infrared clusters or stellar ...

    • Panchromatic averaged stellar populations 

      Riffel, Rogério; Bonatto, Charles Jose; Fernandes, Roberto Cid; Pastoriza, Miriani Griselda; Balbinot, Eduardo (2011) [Journal article]
      We study how the spectral fitting of galaxies, in terms of light fractions, derived in one spectral region translates into another region, by using results from evolutionary synthesis models. In particular, we examine ...
