利用IRAM北向扩展毫米波阵列，我们用S500μm≥80mJy对赫歇尔天体物理大面积探测中探测到的13个亮星系进行了红移测量。我们报告了12个独立来源的可靠光谱红移，这些红移来自3毫米和2毫米波段的扫描，每个波段覆盖高达31 GHz，并基于至少两条发射线的检测。光谱红移位于L(⊙)星系2.081013的范围内。我们还提出了对光谱能量分布的重新分析，包括在3 mm和2 mm处测量的连续谱通量密度，以得出源的总体性质。基于NOEMA对高z星系红移的有效测量，概述了未来的前景，包括对所有最亮的Herschel星系的全面调查。
Using the IRAM NOrthern Extended Millimeter Array (NOEMA), we conducted a program to measure redshifts for 13 bright galaxies detected in the Herschel Astrophysical Large Area Survey with S500 μm ≥ 80 mJy. We report reliable spectroscopic redshifts for 12 individual sources, which are derived from scans of the 3 and 2 mm bands, covering up to 31 GHz in each band, and are based on the detection of at least two emission lines. The spectroscopic redshifts are in the range 2.08 1013 L⊙) galaxies. We also present a reanalysis of the spectral energy distributions including the continuum flux densities measured at 3 and 2 mm to derive the overall properties of the sources. Future prospects based on these efficient measurements of redshifts of high-z galaxies using NOEMA are outlined, including a comprehensive survey of all the brightest Herschel galaxies.
