摘要:

本文给出了z ~ 3.09原星系团SSA 22场中367个源的VLT VIMOS、Keck DEIMOS和Keck LRIS多目标谱。通过模板匹配对源进行了光谱分类,新识别了206个河外源,包括36个z > 2 Lyman break星系(LBG)和Lyman-α发射体(LAEs),8个原星系团成员,以及来自SSA 22 ~ 400 ks Chandra深度巡天的94个X射线源。此外,在我们的研究所涵盖的区域,我们分别将1.0 < z < 2.0,z > 3.4和X射线发射源的可靠红移数量增加了约4,13和6倍。我们比较我们的结果与过去的光谱调查的SSA 22调查的完整性的LBG和X射线性质的新的光谱分类源在SSA 22字段。

英文摘要:

We present VLT VIMOS, Keck DEIMOS and Keck LRIS multi-object spectra of 367 sources in the field of the z ~ 3.09 protocluster SSA22. Sources are spectroscopically classified via template matching, allowing new identifications for 206 extragalactic sources, including 36 z > 2 Lyman-break galaxies (LBGs) and Lyman-α emitters (LAEs), 8 protocluster members, and 94 X-ray sources from the ~ 400 ks Chandra deep survey of SSA22. Additionally, in the area covered by our study, we have increased by ~ 4, 13, and 6 times the number of reliable redshifts of sources at 1.0 < z < 2.0, at z > 3.4, and with X-Ray emission, respectively. We compare our results with past spectroscopic surveys of SSA22 to investigate the completeness of the LBGs and the X-Ray properties of the new spectroscopically-classified sources in the SSA22 field.
