EFFECTS OF STARBURST MERGERS AT Z~1 TO THE IR/SUBMM SURVEYS

We use galaxy aggregation dynamics together with a possible merger-driven starburst and AGN phenomena to investigate the effects of these activities to the strong evolution of infrared and submillimeter deep surveys. We found that a population with a fast evolving infrared burst phase triggered by gas-rich mergers at z~1 could contribute significantly to the strong evolution of the IRAS, ISO and SCUBA deep surveys, while being compatible with the current observational limits of the cosmic infrared background and the redshift distributions. The major difference of our current model prediction is that we see a fast convergence of the differential number counts at 60um below 50mJy, which is about a factor of two brighter than other model predictions. Further infrared satellites like SIRTF and Astro-F would give strong constraints to the models.
