摘要:

我们提出了深J-,H-和KS-波段成像数据的MOIRCS深调查(MODS),这是进行了多目标红外相机和光谱仪(MOIRCS)安装在斯巴鲁望远镜在GOODS-北地区。对于J=23.9、H=22.8和Ks=22.8(织女星星等)的点源,在103弧分^[2](宽视场)上,数据达到了5 σ的总极限星等。在28弧分^2的测区中,这是MODS的超深场(深场),数据达到了J=24.8、H=23.4和Ks=23.8的5西格玛深度。组合图像的空间分辨率为FWHM ~ 0.6 arcsec和~ 0.5 arcsec的宽和深领域的所有波段,分别。将MODS数据与HST、Spitzer和GOODS领域的其他地基望远镜的多波长公开数据相结合,我们构建了一个多波长的KS选择源测光表。利用该星表,我们给出了被探测天体的KS波段数和近红外颜色分布,并演示了高红移星系的近红外颜色选择技术。这些数据和目录可通过互联网公开获取。

英文摘要:

We present deep J-, H-, and Ks-band imaging data of the MOIRCS Deep Survey (MODS), which was carried out with Multi-Object Infrared Camera and Spectrograph (MOIRCS) mounted on the Subaru telescope in the GOODS-North region. The data reach 5sigma total limiting magnitudes for point sources of J=23.9, H=22.8, and Ks=22.8 (Vega magnitude) over 103 arcmin^2 (wide field). In 28 arcmin^2 of the survey area, which is ultra deep field of the MODS (deep field), the data reach the 5sigma depths of J=24.8, H=23.4, and Ks=23.8. The spatial resolutions of the combined images are FWHM ~ 0.6 arcsec and ~ 0.5 arcsec for the wide and deep fields in all bands, respectively. Combining the MODS data with the multi-wavelength public data taken with the HST, Spitzer, and other ground-based telescopes in the GOODS field, we construct a multi-wavelength photometric catalog of Ks-selected sources. Using the catalog, we present Ks-band number counts and near-infrared color distribution of the detected objects, and demonstrate some selection techniques with the NIR colors for high redshift galaxies. These data and catalog are publicly available via internet.
