摘要: We present a comparison of the physical properties rest-frame 250-μm-selected sample massive, dusty galaxies from 0 1 SMGs have an average star formation rate (SFR) 390+80−70 M⊙ yr−1, which is 120 times that low-redshift matched in stellar mass to (SFR = 3.3 ± 0.2 yr−1). The harbour substantial dust ( 1.2+0.3−0.2×109 M⊙), compared (1.6 0.1) × 108 M⊙ for galaxies. At low redshifts, luminosity dominated by diffuse interstellar medium, whereas large fraction originates star-forming regions. same mass, are offset towards higher SFR H-ATLAS This not only due gas but also because they undergoing more efficient mode formation, consistent with their bursty histories. between and similar found CO studies, suggesting as good tracer molecular CO.
