    • SDSS-IV MaNGA : environmental dependence of stellar age and metallicity gradients in nearby galaxies 

      Zheng, Zheng; Wang, Huiyuan; Ge, Junqiang; Mao, Shude; Li, Cheng; Li, Ran; Mo, Houjun; Goddard, Daniel; Bundy, Kevin; Li, Hongyu; Nair, Preethi B.; Lin, Lihwai; Long, Richard J.; Riffel, Rogério; Thomas, D.; Masters, K.L.; Bizyaev, D.; Brownstein, Joel R.; Zhang, Kai; Law, David R.; Drory, Niv; Lopes, Alexandre Roman; Malanushenko, E. (2017) [Artigo de periódico]
      We present a study on the stellar age and metallicity distributions for 1105 galaxies using the STARLIGHT software on MaNGA (Mapping Nearby Galaxies at APO) integral field spectra.We derive age and metallicity gradients ...

    • The growth of the central region by acquisition of counterrotating gas in star-forming galaxies 

      Chen, Yanmei; Shi, Yong; Tremonti, Christy A.; Bershady, Matthew A.; Merrifield, Michael; Emsellem, Eric; Jin, Yifei; Huang, Song; Fu, Hai; Wake, D.A.; Bundy, Kevin; Stark, David V.; Lin, Lihwai; Argudo-Fernández, Maria; Storchi-Bergmann, Thaisa; Bizyaev, D.; Brownstein, Joel R.; Bureau, Martin; Chisholm, John P.; Drory, Niv; Guo, Qi; Hao, Lei; Hu, Jian; Li, Cheng; Li, Ran; Lopes, Alexandre Roman; Pan, K.; Riffel, Rogemar André; Thomas, D.; Wang, Lan; Westfall, Kyle B.; Yan, Renbin (2016) [Artigo de periódico]
      Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the importance of external gas acquisition in ...
