| الوصف: | A large fraction of the luminous distant submillimetre-wave galaxies recently detected using the Submillimetre Common-User Bolometer Array (SCUBA) camera on the James Clerk Maxwell Telescope appear to be associated with interacting optical counterparts. We investigate the nature of these systems using a simple hierarchical clustering model of galaxy evolution, in which the large luminosity of the SCUBA galaxies is assumed to be generated at the epoch of galaxy mergers in a burst of either star formation activity or the fueling of an active galactic nucleus (AGN). The models are well constrained by the observed spectrum of the far-infrared/submillimetre-wave background radiation and the 60-µm counts of low-redshift IRAS galaxies. The ratio between the total amount of energy released during a merger and the mass of dark matter involved must increase sharply with redshift z at z < ∼ 1, and then decrease at greater redshifts. This result is independent of the fraction of the luminosity of mergers that is produced by starbursts and AGN. One additional parameter – the |
