利用佛罗里达多目标成像近红外光栅观测光谱仪（FLAMINGOS），我们进行了FLAMINGOS河外巡天（FLAMEX），一个深成像调查，覆盖7.1 deg 2的18.6 deg 2的NOAO深宽视场调查（NDWFS）地区。FLAMEX是第一个在J和Ks滤波器中成像的深，宽区域，近红外调查，并且比以前任何可比深度的近红外调查都要大。FLAMEX的目的是通过提供大质量星系群在1 < z < 2时的静止标架光学光度测量，促进对星系和星系团演化的研究。这项工作的目的是产生一个公共数据集，补充和扩大现有的调查套件在NDWFS领域。我们提出了一个概述的FLAMEX和初步结果的基础上~150,000 KS选择的来源在Bootes领域。我们描述的意见和减少，量化的数据质量，并验证数量计数与以前的调查结果是一致的。最后，我们评论这个样本的实用程序的ERO人口的详细研究，并提出了第一个光谱确认的z > 1星系团检测使用联合FLAMEX，NDWFS，和斯皮策IRAC浅调查数据集。
Using the Florida Multi-object Imaging Near-IR Grism Observational Spectrometer (FLAMINGOS), we have conducted the FLAMINGOS Extragalactic Survey (FLAMEX), a deep imaging survey covering 7.1 deg2 within the 18.6 deg2 NOAO Deep Wide-Field Survey (NDWFS) regions. FLAMEX is the first deep, wide-area, near-infrared survey to image in both the J and Ks filters, and is larger than any previous NIR survey of comparable depth. The intent of FLAMEX is to facilitate the study of galaxy and galaxy cluster evolution at 1 < z < 2 by providing rest-frame optical photometry for the massive galaxy population at this epoch. This effort is designed to yield a public data set that complements and augments the suite of existing surveys in the NDWFS fields. We present an overview of FLAMEX and initial results based on ~150,000 Ks-selected sources in the Boötes field. We describe the observations and reductions, quantify the data quality, and verify that the number counts are consistent with results from previous surveys. Finally, we comment on the utility of this sample for detailed study of the ERO population, and present one of the first spectroscopically confirmed z > 1 galaxy clusters detected using the joint FLAMEX, NDWFS, and Spitzer IRAC Shallow Survey data sets.
