| Résumé | We study the dust properties of galaxies in the redshift range 0.1 less than or similar to z less than or similar to 2.8 observed by the Herschel Space Observatory in the field of the Great Observatories Origins Deep Survey-North as part of the PACS Extragalactic Probe (PEP) and Herschel Multi-tiered Extragalactic Survey (HerMES) key programmes. Infrared (IR) luminosity (L-IR) and dust temperature (T-dust) of galaxies are derived from the spectral energy distribution fit of the far-IR (FIR) flux densities obtained with the PACS and SPIRE instruments onboard Herschel. As a reference sample, we also obtain IR luminosities and dust temperatures of local galaxies at z < 0.1 using AKARI and IRAS data in the field of the Sloan Digital Sky Survey. We compare the L-IR-T-dust relation between the two samples and find that the median T-dust of Herschel-selected galaxies at z greater than or similar to 0.5 with L-IR greater than or similar to 5 x 10(10) L-circle dot appears to be 2-5 K colder than that of AKARI-selected local galaxies with similar luminosities, and the dispersion in T-dust for high-z galaxies increases with L-IR due to the existence of cold galaxies that are not seen among local galaxies. We show that this large dispersion of the L-IR-T-dust relation can bridge the gap between local star-forming galaxies and high-z submillimetre galaxies (SMGs). We also find that three SMGs with very low T-dust (less than or similar to 20 K) covered in this study have close neighbouring sources with similar 24-mu m brightness, which could lead to an overestimation of FIR/(sub) millimetre fluxes of the SMGs. |
