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

在z = 3的大质量星系周围的大规模ly - α发射线星云可以揭示这些星系形成的许多信息。我们已经成功地使用SAURON在z = 3:094的SSA22原星团的两个亚毫米星系（LAB-1和2）中绘制了这种发射的形态和运动学图，寻找强烈的超风流出的证据-星系形成理论的重要组成部分。在实验室-2中，我们发现了108年历史的流出物的壮观后果，其形式是一个100kpc规模的吸收HI的壳（Wilman， Gerssen等人，2005,Nature）；在LAB-1的ly - α发射中有一个较小的空腔，这表明流出物的进化程度较低。观测的目的是完成一个05A项目，通过索伦对另一个亚毫米星系和两个高z射电星系的观测，探测这种喷流的演变以及agn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.
