The Imperial IRAS-FSC Redshift Catalogue (IIFSCz)

TL;DR

The IIFSCz is a comprehensive galaxy catalogue with redshifts and flux predictions, aiding infrared/submm survey validation, large-scale structure studies, and galaxy evolution research.

Contribution

It provides the first extensive redshift catalogue of IRAS 60 micron-selected galaxies with combined spectroscopic and photometric redshifts, and flux predictions for diverse wavelengths.

Findings

90% of sources have redshift data for S(60)>0.36 Jy

Catalogue includes 60,303 galaxies with multiwavelength data

Supports validation of infrared and submm/mm surveys

Abstract

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.
