Louise O. V. Edwards, Dario Fadda, Andrea Biviano, Francine R. Marleau

摘要:

我们提出了一个光度分析的星系团阿贝尔1763在可见光和红外波长。包括使用Palomar 200 in望远镜获得的完全缩小的r ',J,H和Ks图像,以及斯皮策的IRAC和MIPS图像。该集群覆盖了约3维里半径与深24微米成像(5?深度为0.2 mJy)。这个40'乘40'的相同场被覆盖在所有四个IRAC波段以及更长波长的MIPS波段(70和160 um)中。r'成像覆盖0.8 deg 2到25.5等,并与MIPS视场的大部分重叠。J,H,Ks的图像覆盖了星系团的核心和大约一半的丝状星系,这些丝状星系向邻近的星系团Abell 1770延伸。这第一,在一系列的论文Abell 1763,讨论了数据减少方法和源提取技术用于每个数据集。我们目前的目录红外(IR)源(与24和/或70微米的发射)和他们相应的发射在光学(u ',g',r ',i',z '),和近远红外(J,H,Ks,IRAC,和MIPS 160微米)。我们通过NASA/IPAC红外科学档案(IRSA)向社区提供目录和缩小图像。

英文摘要:

We present a photometric analysis of the galaxy cluster Abell 1763 at visible and infrared wavelengths. Included are fully reduced images in r', J, H, and Ks obtained using the Palomar 200in telescope, as well as the IRAC and MIPS images from Spitzer. The cluster is covered out to approximately 3 virial radii with deep 24um imaging (a 5? depth of 0.2 mJy). This same field of 40' by 40' is covered in all four IRAC bands as well as the longer wavelength MIPS bands (70 and 160um). The r' imaging covers 0.8 deg2 down to 25.5 magnitudes, and overlaps with most of the MIPS field of view. The J, H, Ks images cover the cluster core and roughly half of the filament galaxies, which extend towards the neighboring cluster, Abell 1770. This first, in a series of papers on Abell 1763, discusses the data reduction methods and source extraction techniques used for each dataset. We present catalogs of infrared (IR) sources (with 24 and/or 70um emission) and their corresponding emission in the optical (u', g', r', i', z'), and Near- to Far-IR (J, H, Ks, IRAC, and MIPS 160um). We provide the catalogs and reduced images to the community through the NASA/IPAC Infrared Science Archive (IRSA).
