帝国IRAS-FSC红移星表
The Imperial IRAS-FSC Redshift Catalogue (IIFSCz)
摘要:
我们提出了一个新的目录,帝国IRAS-FSC红移目录(IIFSCz),60,303星系选择在60微米的IRAS暗源目录(FSC)。IIFSCz包括精确的位置,光学,近红外和/或无线电识别,光谱红移(如果有的话)或光度红移(如果可能的话),预测的远红外(FIR)和亚毫米(submm)通量,范围从12到1380微米,基于最佳拟合红外模板。大约55%的星系在IIFSCz的光谱红移和另外20%的光度红移通过训练集或模板拟合方法获得。当S(60)>0.36 Jy时,即FSC的90%完全性极限,90%的源具有光谱或光度红移。IIFSCz的科学应用包括验证当前和即将进行的红外和亚毫米/毫米调查,如AKARI,普朗克和赫歇尔,稀有源人口的后续研究,大尺度结构和星系偏差,本地多波长光度函数和源计数。该目录可从http://astro.imperial.ac.uk/~mrr/fss/公开获取
英文摘要:
We present a new catalogue, the Imperial IRAS-FSC Redshift Catalogue (IIFSCz), of 60,303 galaxies selected at 60 micron from the IRAS Faint Source Catalogue (FSC). The IIFSCz consists of accurate position, optical, near-infrared and/or radio identifications, spectroscopic redshift (if available) or photometric redshift (if possible), predicted far-infrared (FIR) and submillimetre (submm) fluxes ranging from 12 to 1380 micron based upon the best-fit infrared template. About 55% of the galaxies in the IIFSCz have spectroscopic redshifts and a further 20% have photometric redshifts obtained through either the training set or the template-fitting method. For S(60)>0.36 Jy, the 90% completeness limit of the FSC, 90% of the sources have either spectroscopic or photometric redshifts. Scientific applications of the IIFSCz include validation of current and forthcoming infrared and submm/mm surveys such as AKARI, Planck and Herschel, follow-up studies of rare source populations, large-scale structure and galaxy bias, local multiwavelength luminosity functions and source counts. The catalogue is publicly available from http://astro.imperial.ac.uk/~mrr/fss/
