| 英文摘要 | With the aim of exploring the fast evolutionary path from the blue cloud of star-forming galaxies to the red sequence of quiescent galaxies in the local universe, we select a local advanced merging infrared luminous and ultraluminous galaxy (adv-merger (u)lirgs) sample and perform careful dust extinction corrections to investigate their positions in the star formation rate-m-*, u-r, and nuv-r color-mass diagrams. the sample consists of 89 (u) lirgs at the late merger stage, obtained from cross-correlating the infrared astronomical satellite point source catalog redshift survey and 1 jy ulirgs samples with the sloan digital sky survey dr7 database. our results show that 74% +/- 5% of adv-merger (u) lirgs are localized above the 1 sigma line of the local star-forming galaxy main sequence. we also find that all adv-merger (u) lirgs are more massive than and as blue as the blue cloud galaxies after corrections for galactic and internal dust extinctions, with 95% +/- 2% and 81% +/- 4% of them outside the blue cloud on the u-r and nuv-r color-mass diagrams, respectively. these results, combined with the short timescale for exhausting the molecular gas reservoir in adv-merger (u) lirgs (3 x 10(7) to 3 x 10(8) years), imply that the adv-merger (u) lirgs are likely at the starting point of the fast evolutionary track previously proposed by several groups. while the number density of adv-merger (u) lirgs is only similar to 0.1% of the blue cloud star-forming galaxies in the local universe, this evolutionary track may play a more important role at high redshift. |
