We present multi-waveband optical imaging data obtained from observations of the Subaru/XMM-Newton Deep Survey (SXDS). The survey field, centered at R.A.=02:18:00, decl.=-05:00:00, has been the focus of a wide range of multi-wavelength observing programs spanning from X-ray to radio wavelengths. A large part of the optical imaging observations are carried out with Suprime-Cam on Subaru Telescope at Mauna Kea in the course of Subaru Telescope Observatory Projects. This paper describes our optical observations, data reduction and analysis procedures employed, and the characteristics of the data products. A total area of 1.22 sqdeg is covered in five contiguous sub-fields, each of which corresponds to a single Suprime-Cam field of view (34'x27'), in five broad-band filters B, V, Rc, i', z' to the depths of B=28.4, V=27.8, Rc=27.7, i'=27.7 and z'=26.6 (AB, 3-sigma, 2-arcsec aperture). The data are reduced and compiled into five multi-waveband photometric catalogs, separately for each Suprime-Cam pointing. The i'-band catalogs contain about 900,000 objects, making the SXDS catalogs one of the largest multi-waveband catalogs in corresponding depth and area coverage. The SXDS catalogs can be used for an extensive range of astronomical applications such as the number density of the Galactic halo stars to the large scale structures at the distant universe. The number counts of galaxies are derived and compared with those of existing deep extragalactic surveys. The optical data, the source catalogs, and configuration files used to create the catalogs are publicly available via the SXDS web page (http://www.naoj.org/Science/SubaruProject/SXDS/index.html)
The Subaru/XMM-Newton Deep Survey (SXDS) -VII. Clustering Segregation with Ultraviolet and Optical Luminosities of Lyman-Break Galaxies at z~3
利用Subaru/XMM-Newton Deep Field的光学到近红外波段的深空多波段成像数据，研究了z~3处的Lyman-break星系（LBG）的成团特性.在561弧分^2至z '= 25.5的一个连续区域内，通过U-V和V-z'颜色选择LBG。我们研究的集群强度的依赖关系的静止帧UV和光学星等，这可以是恒星形成率和恒星质量的指标，分别。的相关长度被发现是一个强大的功能，紫外线和光学星等与更明亮的星系被聚集在这两种情况下比微弱的。此外，相关长度是依赖于UV和光学星等的组合，在这个意义上，星系明亮的光学星等有大的相关长度，而不考虑UV星等，而星系暗淡的光学星等的相关长度随着UV亮度的降低而降低。这些结果表明，大恒星质量的星系总是属于大质量的晕，他们可以有不同的恒星形成率，而小恒星质量的星系居住在较小的质量晕，只有当他们有低的恒星形成率。恒星质量和恒星形成速率似乎有一个上限，这取决于暗晕的质量。

Subaru Deep Survey VI. A Census of Lyman Break Galaxies at z=4 and 5 in the Subaru Deep Fields: Clustering Properties
We investigate the clustering properties of 2,600 Lyman Break Galaxies (LBGs) at z=3.5-5.2 in two large blank fields, the Subaru Deep Field and the Subaru/XMM Deep Field (600arcmin^2 each). The angular correlation functions of these LBGs show a clear clustering at both z~4 and 5. The correlation lengths are r_0= 4.1^{+0.2}_{-0.2} and 5.9^{+1.3}_{-1.7} h_{100} ^{-1} Mpc (r_0= 5.1^{+1.0}_{-1.1} and 5.9^{+1.3}_{-1.7} h_{100} ^{-1} Mpc) for all the detected LBGs (for L>L* LBGs) at z~4 and 5, respectively. These correlation lengths correspond to galaxy- dark matter biases of b_g= 2.9^{+0.1}_{-0.1} …
Probing accretion activity in radio sources using 24 micron Spitzer data
我们研究了Subaru/XMM-Newton Deep Field SXDF中36个最亮的射电源。使用来自斯皮策的MIPS 24微米数据，我们希望追踪吸积活动，即使它隐藏在光学波长下，除非遮蔽柱是极端的。我们的研究结果表明，在射电光度函数中断的十年左右时间里，至少有一半，甚至可能是几乎所有的射电源都与吸积类星体有关。这是不正确的，在较低的无线电光度，类星体的分数接近零，一旦紧凑的来源被排除在外。
