cds-question@unistra.frintergalactic-mediumvisible-astronomyspectroscopyinfrared-photometryredshiftedWe conducted a deep spectroscopic survey, named SSA22-HIT, in the SSA22 field with the DEep Imaging MultiObject Spectrograph (DEIMOS) on the Keck telescope, designed to tomographically map high-z H i gas through analysis of Ly{alpha} absorption in background galaxies spectra. In total, 198 galaxies were spectroscopically confirmed at 2.5<z<6 with a few low-z exceptions in the 26x15arcmin^2^ area, of which 148 were newly determined in this study. Our redshift measurements were merged with previously confirmed redshifts available in the 34x27arcmin^2^ area of the SSA22 field. This compiled catalog containing 730 galaxies of various types at z>2 is useful for various applications, and it is made publicly available. Our SSA22-HIT survey has increased by approximately twice the number of spectroscopic redshifts of sources at z>3.2 in the observed field. From a comparison with publicly available redshift catalogs, we show that our compiled redshift catalog in the SSA22 field is comparable to those among major extragalactic survey fields in terms of a combination of wide area and high surface number density of objects at z>2. About 40% of the spectroscopically confirmed objects in SSA22-HIT show reasonable quality of spectra in the wavelengths shorter than Ly{alpha} when a sufficient amount of smoothing is adopted. Our data set enables us to make the HI tomographic map at z>~3, which we present in a parallel study.2023AJ....165..208Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/165/208CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)II/261 : GOODS initial results (Giavalisco+, 2004)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/314 : UKIDSS-DR8 LAS, GCS and DXS Surveys (Lawrence+ 2012)VII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)J/PASP/110/863 : Stellar Spectral Flux Library; 1150 - 25000 A (Pickles 1998)J/ApJ/592/728 : Lyman break galaxies at redshift z~3 (Steidel+, 2003)J/ApJ/614/671 : Hot, dusty ultraluminous galaxies at z~2 (Chapman+, 2004)J/ApJ/622/772 : Redshift survey of submillimeter galaxies (Chapman+, 2005)J/ApJ/651/61 : Optically thick absorbers near luminous QSO (Hennawi+, 2006)J/ApJS/172/70 : zCOSMOS-bright catalog, DR3 (Lilly+, 2007)J/MNRAS/400/299 : Chandra deep protocluster survey (Lehmer+, 2009)J/A+A/512/A12 : VLT/VIMOS spectroscopy GOODS-South field (Balestra+, 2010)J/MNRAS/421/3060 : Subaru/XMM Deep Field radio imaging.
