我们目前的第二个主要发布的数据从悉尼-澳大利亚天文台多目标积分场摄谱仪（SAMI）星系调查。数据发布二包括1559个星系的数据，约占全部调查的50%。包括Galerkin的红移范围为0.004 [11]，速度色散向中心强烈增加，而低于log（M-*/M-圆点）< 10，我们没有发现中心速度色散明显增加的证据。这表明，对于有或没有弥散主导的凸起的星系，log（M */M圆点）附近的过渡质量类似于10。
We present the second major release of data from the Sydney - Australian Astronomical Observatory Multi-Object Integral Field Spectrograph (SAMI) Galaxy Survey. Data Release Two includes data for 1559 galaxies, about 50 per cent of the full survey. Galaxies included have a redshift range 0.004 11], the velocity dispersion strongly increases towards the centre, whereas below log (M-*/M-circle dot) < 10 we find no evidence for a clear increase in the central velocity dispersion. This suggests a transition mass around log (M-*/M-circle dot) similar to 10 for galaxies with or without a dispersion-dominated bulge.
