| Description |
We propose to establish a large, complete Herschel spectroscopic atlas of the low-redshift ULIRG population, via PACS-SPIRE spectroscopy of 45 local ULIRGs. Our observations will combine with existing Herschel data to complete a purely flux limited sample of 52 ULIRGs at z<0.2. This sample comprises the most well-studied low-redshift ULIRGs in existence; they all have mid-IR spectra from Spitzer in both low and high resolution mode, many have HST imaging, and about half have X-ray observations. We will measure the physical & chemical properties of the starbursts and AGN in unprecedented detail, construct new mid-far-IR diagnostic diagrams, and determine robust calibrations for key observables of ULIRGs in the distant Universe. Our program will form a cornerstone of the Herschel spectroscopic legacy, providing (1) a comprehensive database for community exploitation, (2) a firm anchor for studies of ULIRGs in the high redshift Universe, and (3) one of the most important input catalogues for ALMA. As our intention is to create an atlas for the community, we waive all proprietary rights. |
