    • Spectral evolution of star clusters in the Large Magellanic Cloud : I. blue concentrated clusters in the range 40-300 Myr 

      Santos Junior, Joao Francisco Coelho dos; Claria Olmedo, Juan Jose; Ahumada, Andrea Veronica; Bica, Eduardo Luiz Damiani; Piatti, Andres E.; Parisi, M. C. (2006) [Artigo de periódico]
      Aims. Integrated spectroscopy of a sample of 17 blue concentrated Large Magellanic Cloud (LMC) clusters is presented and its spectral evolution studied. The spectra span the range ≈(3600−6800) Å with a resolution of ≈14Å ...

    • Star formation in distant starburst galaxies 

      Bonatto, Charles Jose; Bica, Eduardo Luiz Damiani; Pastoriza, Miriani Griselda; Alloin, Danielle Marie (2000) [Artigo de periódico]
      This paper discusses the stellar population content of distant (5 000kms−1 VR 16 000kms−1) galaxies with enhanced star-formation activity. Distinction is made between isolated galaxies and galaxies morphologically disturbed, ...

    • Structures in surface-brightness profiles of LMC and SMC star clusters : evidence of mergers? 

      Carvalho, Luziane Oliveira; Saurin, Tiago Abreu; Bica, Eduardo Luiz Damiani; Bonatto, Charles Jose; Schmidt, Alex Andre (2008) [Artigo de periódico]
      Context. The LMC and SMC are rich in binary star clusters, and some mergers are expected. It is thus important to characterise single clusters, binary clusters and candidates for mergers. Aims. We selected a sample of star ...

    • The VISCACHA survey : III. Star clusters counterpart of the Magellanic Bridge and Counter-Bridge in 8D 

      Dias, Bruno Moreira de Souza; Angelo, Mateus S.; Oliveira, Raphael Augusto Pereira de; Maia, Francisco F. S.; Parisi, M. C.; De Bórtoli, Bruno Javier; Souza, Stefano O.; Santrich, Orlando J. Katime; Bassino, Lilia Patricia; Barbuy, Beatriz; Bica, Eduardo Luiz Damiani; Geisler, Doug; Kerber, Leandro de Oliveira; Pérez Villegas, Maria de Los Angeles; Quint, Bruno C.; Sanmartim, David; Santos Junior, Joao Francisco Coelho dos; Westera, Pieter (2021) [Artigo de periódico]
      Context. The interactions between the Small and Large Magellanic Clouds (SMC and LMC) created the Magellanic Bridge; a stream of gas and stars pulled out of the SMC towards the LMC about 150 Myr ago. The tidal counterpart ...

    • The VISCACHA survey : II. Structure of star clusters in the Magellanic clouds periphery 

      Santos Junior, Joao Francisco Coelho dos; Maia, Francisco F. S.; Dias, Bruno Moreira de Souza; Kerber, Leandro de Oliveira; Piatti, Andres E.; Bica, Eduardo Luiz Damiani; Angelo, Mateus S.; Minniti, Dante; Pérez Villegas, Maria de Los Angeles; Roman-Lopes, Alexandre; Westera, Pieter; Fraga, Luciano; Quint, Bruno C.; Sanmartim, David (2020) [Artigo de periódico]
      We provide a homogeneous set of structural parameters of 83 star clusters located at the periphery of the Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC). The clusters’ stellar density and surface brightness ...

    • The VISCACHA survey : I. Overview and first results 

      Maia, Francisco F. S.; Dias, Bruno Moreira de Souza; Santos Junior, Joao Francisco Coelho dos; Kerber, Leandro de Oliveira; Bica, Eduardo Luiz Damiani; Piatti, Andres E.; Barbuy, Beatriz; Quint, Bruno C.; Fraga, Luciano; Sanmartim, David; Angelo, Mateus S.; Hernández Jiménez, José Andrés; Santrich, Orlando J. Katime; Oliveira, Raphael Augusto Pereira de; Pérez Villegas, Maria de Los Angeles; Souza, Stefano O.; Vieira, Rodrigo G.; Westera, Pieter (2019) [Artigo de periódico]
      The VISCACHA(VIsible Soar photometry of star Clusters in tApii and Coxi HuguA) Survey is an ongoing project based on deep photometric observations of Magellanic Cloud star clusters, collected using the SOuthern Astrophysical ...

    • The VISCACHA survey : IV. The SMC West Halo in 8D 

      Dias, Bruno Moreira de Souza; Bica, Eduardo Luiz Damiani; Rocha, João Pedro dos Santos (2022) [Artigo de periódico]
      The structure of the Small Magellanic Cloud (SMC) is very complex, in particular in the periphery that suffers more from the interactions with the Large Magellanic Cloud (LMC). A wealth of observational evidence has been ...

    • The VISCACHA survey : VIII. Chemical evolution history of the small Magellanic cloud west halo clusters 

      Saroon, Sasi; Dias, Bruno; Tsujimoto, Takuji; Parisi, M. C.; Maia, Francisco F. S.; Kerber, Leandro de Oliveira; Bekki, Kenji; Minniti, Dante; Oliveira, Raphael Augusto Pereira de; Westera, Pieter; Santrich, Orlando J. Katime; Bica, Eduardo Luiz Damiani; Sanmartim, David; Quint, Bruno C.; Fraga, Luciano (2023) [Artigo de periódico]
      The chemical evolution history of the Small Magellanic Cloud (SMC) has been a matter of debate for decades. The challenges in understanding the SMC chemical evolution are related to a very slow star formation rate (SFR) ...

    • The VISCACHA survey : V. Rejuvenating three faint SMC clusters 

      Bica, Eduardo Luiz Damiani; Maia, Francisco F. S.; Oliveira, Raphael Augusto Pereira de; Dias, Bruno Moreira de Souza; Santos Junior, Joao Francisco Coelho dos; Rocha, João Pedro dos Santos; Kerber, Leandro de Oliveira; Carvalho, João Francisco Gardin de; Armond, Ana Cristina Moreira Machado Zadra; Parisi, M. C.; Souza, Stefano O.; Barbuy, Beatriz (2022) [Artigo de periódico]
      We present the analysis of three faint clusters of the Small Magellanic Cloud RZ 82, HW 42, and RZ 158. We employed the SOAR telescope instrument SAM with adaptive optics, allowing us to reach to V ∼ 23–24 mag, unprecedentedly, ...
