24 Sep 2015 | Abstract: | We 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
MOSFIRE, an infrared multi-object spectrometer 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. | Source: | arXiv, 1509.7172 | Services: | Forum | Review | PDF | Favorites |
