    • Cardinal kinematics – I. : rotation fields of the APOGEE survey 

      Kordopatis, Georges; Wyse, Rosemary F.G.; Chiappini, C.C.M.; Minchev, Ivan; Anders, Friedrich; Santiago, Basilio Xavier (2017) [Artigo de periódico]
      Correlations between stellar chemistry and kinematics have long been used to gain insight into the evolution of the Milky Way Galaxy. Orbital angular momentum is a key physical parameter and it is often estimated from ...

    • Integrated spectra of Milky Way globular clusters 

      Moura, Tatiana; Trevisan, Marina; Barbuy, Beatriz; Rossi, Silvia (2019) [Artigo de periódico]
      Integrated spectra of Milky Way globular clusters (GCs) are reproduced by computing synthetic spectra taking into account individual element abundances. Five clusters were selected from their location in the Galactic bulge, ...

    • MaNGA 8313-1901 : gas accretion observed in a blue compact dwarf galaxy 

      Ju, Mengting; Yin, Jun; Liu, Rongrong; Hao, Lei; Shao, Zhengyi; Feng, Shuai; Riffel, Rogério; Liu, Chenxu; Stark, David V.; Shen, Shiyin; Telles, Jose Eduardo; Fernández-Trincado, José Gregorio; Wang, Junfeng; Xu, Haiguang; Bizyaev, D.; Rong, Yu (2022) [Artigo de periódico]
      Gas accretion is an important process in the evolution of galaxies, but it has limited direct observational evidences. In this paper, we report the detection of a possible ongoing gas accretion event in a blue compact dwarf ...

    • Milky Way satellite census : II. Galaxy–halo connection constraints including the impact of the Large Magellanic Cloud 

      Nadler, Ethan O.; Santiago, Basilio Xavier; DES Collaboration (2020) [Artigo de periódico]
      The population of Milky Way (MW) satellites contains the faintest known galaxies and thus provides essential insight into galaxy formation and dark matter microphysics. Here we combine a model of the galaxy–halo connection ...

    • SDSS-IV MaNGA : exploring the local scaling relations for N/O 

      Schaefer, Adam L.; Tremonti, Christy A.; Kauffmann, Guinevere; Andrews, Brett H.; Bershady, Matthew A.; Boardman, Nicholas Fraser; Bundy, Kevin; Drory, Niv; Fernández-Trincado, José Gregorio; Preece, Holly; Riffel, Rogério; Riffel, Rogemar André; Sánchez, Sebastián F. (2022) [Artigo de periódico]
      We present, for the first time, the relationship between local stellar mass surface density, Σ*, and N/O derived from SDSS-IV MaNGA data, using a sample of 792,765 high signal-to-noise ratio star-forming spaxels. Using a ...
