    • The absence of an environmental dependence in the mass-metallicity relation at z = 2 

      Kacprzak, Glenn G.; Yuan, Tiantian; Nanayakkara, Themiya; Kobayashi, Chiaki; Tran, Kim V. Y. H.; Kewley, Lisa J.; Glazebrook, Karl; Spitler, Lee; Taylor, Philip; Cowley, Michael; Labbe, Ivo; Straatman, Caroline; Tomczak, Adam (2015-04-02)
      We investigate the environmental dependence of the mass-metallicity relation at z = 2 with MOSFIRE/Keck as part of the ZFIRE survey. Here, we present the chemical abundance of a Virgo-like progenitor at z = 2.095 that has ...

    • Azimuthal variations of gas-phase oxygen abundance in NGC 2997 

      Ho, I-Ting; Meidt, Sharon E.; Kudritzki, Rolf-Peter; Groves, Brent A.; Seibert, Mark; Madore, Barry F.; Schinnerer, Eva; Rich, Jeffrey A.; Kobayashi, Chiaki; Kewley, Lisa J. (2018-10-15)
      The azimuthal variation of the HII region oxygen abundance in spiral galaxies is a key observable for understanding how quickly oxygen produced by massive stars can be dispersed within the surrounding interstellar medium. ...

    • Oxygen Loss from Simulated Galaxies and the Metal Flow Main Sequence : Predicting the Dependence on Mass and Environment 

      Taylor, Philip; Kobayashi, Chiaki; Kewley, Lisa J. (2020-08-01)
      We predict the mass fraction of oxygen lost from galaxies in a cosmological simulation as a function of stellar mass and environment at the present day. The distribution with stellar mass is bimodal, separating star-forming ...

    • The Chemical Evolution Carousel of Spiral Galaxies : Azimuthal Variations of Oxygen Abundance in NGC1365 

      Ho, I-Ting; Seibert, Mark; Meidt, Sharon E.; Kudritzki, Rolf-Peter; Kobayashi, Chiaki; Groves, Brent A.; Kewley, Lisa J.; Madore, Barry F.; Rich, Jeffrey A.; Schinnerer, Eva; D'Agostino, Joshua; Poetrodjojo, Henry (2017-08-30)
      The spatial distribution of oxygen in the interstellar medium of galaxies is the key to understanding how efficiently metals that are synthesized in massive stars can be redistributed across a galaxy. We present here a ...

    • The SAMI Galaxy Survey: : extraplanar gas, galactic winds, and their association with star formation history 

      Ho, I-Ting; Medling, Anne M.; Bland-Hawthorn, Joss; Groves, Brent; Kewley, Lisa J.; Kobayashi, Chiaki; Dopita, Michael A.; Leslie, Sarah K.; Sharp, Rob; Allen, James T.; Bourne, Nathan; Bryant, Julia J.; Cortese, Luca; Croom, Scott M.; Dunne, Loretta; Fogarty, L. M. R.; Goodwin, Michael; Green, Andy W.; Konstantopoulos, Iraklis S.; Lawrence, Jon S.; Lorente, Nuria P. F.; Owers, Matt S.; Richards, Samuel; Sweet, Sarah M.; Tescari, Edoardo; Valiante, Elisabetta (2016-04-01)
      We investigate a sample of 40 local, main-sequence, edge-on disc galaxies using integral field spectroscopy with the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey to understand the link between ...
