In our analysis we consider 96 SMGs in the Extended Chandra Deep Field South, 77 of which have 4-19 band photometry. We model the SEDs for these 77 SMGs, deriving a median photometric redshift of z_phot_=2.3+/-0.1. The remaining 19 SMGs have insufficient photometry to derive photometric redshifts, but a stacking analysis of Herschel observations confirms they are not spurious. Assuming that these SMGs have an absolute H-band magnitude distribution comparable to that of a complete sample of z~1-2 SMGs, we demonstrate that they lie at slightly higher redshifts, raising the median redshift for SMGs to z_phot_=2.5+/-0.2. Critically we show that the proportion of galaxies undergoing an SMG-like phase at z>=3 is at most 35%+/-5% of the total population. We derive a median stellar mass of M_*_=(8+/-1)x10^10^ M_{sun}_, although there are systematic uncertainties of up to 5x for individual sources. Assuming that the star formation activity in SMGs has a timescale of ~100 Myr, we show that their descendants at z~0 would have a space density and M_H_ distribution that are in good agreement with those of local ellipticals. In addition, the inferred mass-weighted ages of the local ellipticals broadly agree with the look-back times of the SMG events. Taken together, these results are consistent with a simple model that identifies SMGs as events that form most of the stars seen in the majority of luminous elliptical galaxies at the present day.2014ApJ...788..125Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/788/125CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/155/73 : Photometric redshifts of X-ray sources in CDF-SJ/ApJ/622/772 : Redshift survey of submillimeter galaxies (Chapman+, 2005)J/ApJ/699/1610 : Spitzer survey of submillimeter galaxies (Hainline+, 2009)J/ApJ/707/1201 : LABOCA ECDFS Submillimeter Survey (LESS) (Weiss+, 2009)J/ApJS/191/124 : Optical spectroscopy of ECDF-S X-ray sourcesJ/ApJS/203/15 : Counterparts to 1.4GHz sources in ECDF-S (Bonzini+, 2012)J/ApJ/768/91 : ALMA observations of LESS submm galaxies (Hodge+, 2013)J/MNRAS/442/577 : Selected ALESS submm galaxies radio propertieshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/788/125https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/788/125http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/788/125https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/788/125https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/788/125http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/788/125GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/788/125/table2 (Photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/788/125/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/788/125/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/788/125/table2?GETtext/xml+votable180.050000true53.31025-27.93736110.005555555555555556Cone search capability for table J/ApJ/788/125/table3 (Derived Properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/788/125/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/788/125/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/788/125/table3?GETtext/xml+votable180.050000true53.31025-27.93736110.0055555555555555566/35935 359573.3766364339619036e-19 4.826256797203527e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/788/125?format=asciiRadioInfraredOpticaldefaultJ/ApJ/788/125/table1Summary of PhotometryrecnoRecord number assigned by the VizieR team.
