标题： The FLAMINGOS Extragalactic Survey

摘要： 利用佛罗里达多目标近红外光栅光谱仪（FLAMINGOS），我们开展了FLAMINGOS星系外巡天（FLAMEX），这是一项覆盖18.6平方度NOAO深广域巡天（NDWFS）区域内的7.1平方度深度成像巡天。 FLAMEX是首个在J和Ks波段同时成像的深场宽视场近红外巡天，其规模超过了以往任何具有相同深度的近红外巡天。 FLAMEX的目标是通过为这一时期的大量星系提供框架内光学测光数据，来促进对红移1到2之间星系和星系团演化的研究。 这项工作旨在生成一个公开的数据集，以补充和增强NDWFS区域现有调查套件。 我们概述了FLAMEX，并基于Bootes区域约15万Ks选择源的初步结果进行了描述。 我们描述了观测和数据处理过程，量化了数据质量，并验证了数量计数与先前调查的结果一致。 最后，我们评论了这个样本对于详细研究ERO（红超巨星）群体的效用，并展示了使用FLAMEX、NDWFS和斯皮策红外探测器浅层巡天联合数据集确认的第一个红移大于1的星系团。 显示英文摘要

摘要： 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 square degrees within the 18.6 sq. deg 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 surveys 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 upon ~150,000 Ks-selected sources in the Bootes 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 upon 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.
