cds-question@unistra.frgalaxiesredshiftedgalaxy-classification-systemsPresent-day massive galaxies are composed mostly of early-type objects. It is unknown whether this was also the case at higher redshifts. In a hierarchical assembling scenario the morphological content of the massive population is expected to change with time from disc-like objects in the early Universe to spheroid-like galaxies at present. In this paper we have probed this theoretical expectation by compiling a large sample of massive (M_stellar_>=10^11^h^-2^_70_M{sun}) galaxies in the redshift interval 0<z<3. Our sample of 1082 objects comprises 207 local galaxies selected from Sloan Digital Sky Survey plus 875 objects observed with the Hubble Space Telescope belonging to the Palomar Observatory Wide-field InfraRed/DEEP2 and GOODS NICMOS Survey surveys. 639 of our objects have spectroscopic redshifts. Our morphological classification is performed as close as possible to the optical rest frame according to the photometric bands available in our observations both quantitatively (using the Sersic index as a morphological proxy) and qualitatively (by visual inspection). Using both techniques we find an enormous change on the dominant morphological class with cosmic time. The fraction of early-type galaxies among the massive galaxy population has changed from ~20-30 per cent at z~3 to~70 per cent at z=0. Early-type galaxies have been the predominant morphological class for massive galaxies since only z~1.2013MNRAS.428.1460Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/428/1460CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/382/109 : Massive galaxies in Extended Groth Strip (Trujillo+, 2007)J/MNRAS/427/1666 : Massive galaxies in CANDELS-UDS field (Bruce+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/428/1460https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/428/1460http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/428/1460https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/428/1460https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/428/1460http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/428/1460GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/428/1460/tables1 (Structural parameters from our massive (M>10^11^) SDSS (z<0.03) galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/1460/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/1460/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/1460/tables1?GETtext/xml+votable180.050000true0.883875-10.744666940.0055555555555555566/4289 4312 4343 4346 4359 4410 4491 4515 4519-4520 4550 4577 4606 4706 4954 4957 4961 4966-4967 5080 5083 5086 5115 5298 5343 5371 5376 5528 5626 5701 5715 5769 5772 5841 5858 6034 6074 6083 6213 6245 7204 7266 7324 7352 7355 7412 8203 8208 8228 8320 8327 8341 8351 8367 8378 8391 8705 8714 8750 8760 8802 8813 8841 9141 9187 9207 9209 9381 9443 9463 9467-9468 9470-9471 9891 10182 10194 10272 10375 10378-10379 10382 10394 10401 10434 10456 10519 10533 10553 10624-10625 10802 10842 10869 10879 11010 11041 11044 11086 11114 11118 11290 11588 11905 17213 17233 17755-17756 17857 18001 18794 19114 19319 23206 23208 25950 25981 25989 25997 26060 26070 26100 26102 26389 26393 26422 26424 26452 26495 26519 26563 26574 26584 26590 26596 26615 27086 27117 27128 27317 27365 27413 27491 27625 27652 27760 27774 27800 27849 28064 28067 28075 28143 28149-28150 28154 28249 28251 28253-28254 28273 28302 28346 28365 28371 28377 28406 28414 28436 28475 28517 28555 28564-28565 28572 28606 31405 31715 31724 32462 36733 36766 490193.588997330618193e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/428/1460?format=asciiOpticaldefaultJ/MNRAS/428/1460/tables1Structural parameters from our massive (M>10^11^) SDSS (z<0.03) galaxy samplerecnoRecord number assigned by the VizieR team.
