cds-question@unistra.frgalaxiescatalogsredshiftedWe present the Team Keck Redshift Survey 2 (TKRS2), a near-infrared spectral observing program targeting selected galaxies within the CANDELS subsection of the GOODS-North Field. The TKRS2 program exploits the unique capabilities of the Multi-Object Spectrometer For Infra-Red Exploration (MOSFIRE), which entered service on the Keck I telescope in 2012 and contributes substantially to the study of galaxy spectral features at redshifts inaccessible to optical spectrographs. The TKRS2 project targets 97 galaxies drawn from samples that include z~2 emission-line galaxies with features observable in the JHK bands as well as lower-redshift targets with features in the Y band. We present a detailed measurement of MOSFIRE's sensitivity as a function of wavelength, including the effects of telluric features across the YJHK filters. The largest utility of our survey is in providing rest-frame-optical emission lines for z>1 galaxies, and we demonstrate that the ratios of strong, optical emission lines of z~2 galaxies suggest the presence of either higher N/O abundances than are found in z~0 galaxies or low-metallicity gas ionized by an active galactic nucleus. We have released all TKRS2 data products into the public domain to allow researchers access to representative raw and reduced MOSFIRE spectra.2015AJ....150..153Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/153CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)J/ApJS/207/24 : GOODS-S CANDELS multiwavelength catalog (Guo+, 2013)J/ApJS/206/10 : CANDELS multiwavelength catalog (Galametz+, 2013)J/ApJ/762/46 : GOODS-N spectrophotometry survey (Perez-Gonzalez+, 2013)J/ApJS/193/14 : DEEP3 Galaxy Redshift Survey: GOODS-N field (Cooper+, 2011)J/ApJ/706/158 : Early-type galaxies in PEARS (Ferreras+, 2009)J/ApJ/689/687 : GOODS-N spectroscopic survey (Barger+, 2008)J/ApJ/653/1004 : Galaxies at 1.4<~z<~3.0 in GOODS-North Field (Reddy+, 2006)J/AJ/127/3121 : TKRS catalog of GOODS-North Field (Wirth+, 2004)http://arcoiris.ucsc.edu/TKRS2/ : TKRS2 websitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/153https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/153http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/153https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/153https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/153http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/153GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/150/153/table3 (Redshift catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/153/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/153/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/153/table3?GETtext/xml+votable180.050000true189.101219662.14110330.0055555555555555566/11252https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/153?format=asciiOpticaldefaultJ/AJ/150/153/table3Redshift catalogrecnoRecord number assigned by the VizieR team.
