22 Jul 2003 | | Journal: | Astrophys.J. 597 (2003) 759-767; Erratum-ibid. 603 (2004) 803 | | Subject: | astro-ph | | Affiliation: | INAF - OAP, Padova & OAT, Trieste), Luigi Spinoglio (IFSI, CNR, Roma), Matthew A. Malkan (UCLA, CA | | Abstract: | Averaged spectral energy distributions (SEDs) of active and starburst galaxies from the 12 micron sample in the Local Universe and Quasars, from an optically selected sample at a mean redshift =0.7, are built from optical/near-IR/far-IR (IRAS & ISO) photometric observations. These SEDs are then used to predict at various redshifts the number of Seyfert type 1 and type 2, starburst, normal galaxies, and quasars, that will be detected by future Space Missions dedicated to far-infrared and submillimeter astronomy, like SIRTF and Herschel. These predictions are then compared with the expected capabilities and detection limits of future deep far-IR surveys. Possible ways to identify AGN candidates on far-IR colour-colour plots for follow-up observations are then explored. | | Source: | arXiv, astro-ph/0307386 | | Services: | Forum | Review | PDF | Favorites | |
