observing run: The Lyman-alpha haloes of sub-mm galaxies: exploring superwinds and feedback at z=3

z = 3的大质量星系周围的大尺度Ly-alpha发射线星云可以揭示许多关于这类星系形成的信息。我们已经成功地使用SAURON映射在两个亚毫米星系（LAB-1和2）在SSA 22原星系团在z = 3：094，这种发射的形态和运动学，寻找暴力的超风外流的证据-星系形成理论的一个重要组成部分。在LAB-2中，我们发现了一个108年前的外流的壮观后果，其形式是一个100 kpc规模的吸收HI的壳层（Wilman，Gerssen等人，2005，Nature）; LAB-1中Ly-alpha发射中的一个较小规模的空腔表明了一个演化程度较低的外流。观测的目的是完成05 A计划，通过SAURON对另一个亚毫米星系和两个高Z射电星系的观测，探测这种外流的演变以及活动星系核驱动的喷流对它们的影响。

The large-scale Ly-alpha emission line nebulae around massive galaxies at z = 3 can reveal much about the formation of such galaxies. We have successfully used SAURON to map the morphology and kinematics of this emission in two sub-mm galaxies (LAB-1 & 2) in the SSA22 protocluster at z = 3:094, searching for evidence of violent superwind outflows- a vital ingredient in galaxy formation theories. In LAB-2 we discovered the spectacular aftermath of a several-108 yr-old outflow in the form of a 100 kpc-scale shell of absorbing HI (Wilman, Gerssen et al. 2005, Nature); a smaller-scale cavity in the Ly-alpha emission in LAB-1 suggests a less-evolved outflow. The observations aim to finish a 05A programme to probe the evolution of such outflows and the impact upon them of AGN-driven jets, via SAURON observations of a further sub-mm galaxy and two high-z radio galaxies.
