我们报告的结果，深三维成像调查的哈勃深场北使用金牛座可调滤波器在威廉赫歇尔望远镜。这次巡天的目的是寻找被其他技术遗漏的新的谱线发射天体群，并从一次谱线选择巡天中测量宇宙星星形成率密度。我们在光谱的7100、8100和9100 μ s区域观察到三个连续的窄带切片序列，对应于z = 1时高达1000 Mpc 3的宇宙学体积，下至102 × 10-17 ergs cm-2 s-1的通量极限。调查是足够深，是高度完整的低线光度星系。与现场现有的光谱学交叉匹配，得到了一个小的线光度有限的样品，具有非常高的红移识别完整性，包含7个[O II]，Hβ和Hα发射体，红移范围为0.3-0.9。将其视为直接的星星形成速率选择样本，我们估计宇宙的星星形成历史为z = 1。我们没有发现任何新的人口的线发射物体显着贡献的宇宙学星星形成率密度的证据。相反，从我们完整的窄带样本中，我们发现星星的形成历史与早期宽带成像调查和其他不太深的选线调查的估计是一致的。
We report the results of a deep three-dimensional imaging survey of the Hubble Deep Field North using the Taurus Tunable Filter at the William Herschel Telescope. This survey was designed to search for new line-emitting populations of objects missed by other techniques and to measure the cosmic star formation rate density from a line-selected survey. We observed in three contiguous sequences of narrowband slices in the 7100, 8100, and 9100 Å regions of the spectrum, corresponding to a cosmological volume of up to 1000 Mpc3 at z = 1, down to a flux limit of ∼2 × 10-17 ergs cm-2 s-1. The survey is deep enough to be highly complete for low line luminosity galaxies. Cross-matching with existing spectroscopy in the field results in a small line-luminosity–limited sample, with very high redshift-identification completeness containing seven [O II], Hβ, and Hα emitters over the redshift range 0.3–0.9. Treating this as a direct star formation rate–selected sample, we estimate the star formation history of the universe to z = 1. We find no evidence for any new population of line-emitting objects contributing significantly to the cosmological star formation rate density. Rather, from our complete narrowband sample, we find that the star formation history is consistent with earlier estimates from broadband imaging surveys and other less deep line-selected surveys.
