    • AGB stars as tracers of metallicity and mean age across M 33 

      Cioni, M-R.L.; Irwin, M.J.; Ferguson, A.M.N.; McConnachie, A.; Conn, B.C.; Huxor, A.P.; Ibata, R.A.; Lewis, G.F.; Tanvir, N. (2008)
      Wide-field JHKs near-infrared observations covering an area of 1.8◦ × 1.8◦ centred on M33 were obtained using WFCAM at UKIRT. These data show a large population of intermediate-age asymptotic giant branch (AGB) stars. Aims. ...
