      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 ...

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 : 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, ...

    • UVES analysis of red giants in the bulge globular cluster NGC 6522 

      Barbuy, Beatriz; Cantelli, Elvis William Carvalho; Muniz, Leone V.; Souza, Stefano O.; Chiappini, C.C.M.; Hirschi, Raphael; Cescutti, Gabriele; Pignatari, Marco; Ortolani, Sergio; Kerber, Leandro de Oliveira; Maia, Francisco F. S.; Bica, Eduardo Luiz Damiani; Depagne, Éric (2021) [Artigo de periódico]
      Context. NGC 6522 is a moderately metal-poor bulge globular cluster ([Fe/H] ~ −1.0), and it is a well-studied representative among a number of moderately metal-poor blue horizontal branch clusters located in the bulge. The ...
