An Extragalactic Spectroscopic Survey of the SSA22 Field
  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-\alpha\ 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.
