Description

We spectroscopically survey the galaxy cluster XMM-LSS J02182-05102 (hereafter IRC 0218) using LRIS (optical) and MOSFIRE (near-infrared) on Keck I as part of the ZFIRE survey. IRC 0218 has a narrow redshift range of 1.612 < zspec < 1.635 defined by 33 members of which 20 are at Rproj < 1Mpc. The cluster redshift and velocity dispersion are zcl = 1.6233 ±0.0003 and ±cl = 254 ±50 kms-1. We reach NIR line sensitivities of ∼0.3 10-17 erg s-1 cm-2 that, combined with multi-wavelength photometry,...[Show more]
