The evolution in number density of these extreme objects over cosmic time is the crucial constraining factor for the models of massive galaxy assembly. We select a large sample of ~200 intermediate-redshift massive compacts from the Baryon Oscillation Spectroscopic Survey (BOSS) spectroscopy by identifying point-like Sloan Digital Sky Survey photometric sources with spectroscopic signatures of evolved redshifted galaxies. A subset of our targets have publicly available high-resolution ground-based images that we use to augment the dynamical and stellar population properties of these systems by their structural parameters. We confirm that all BOSS compact candidates are as compact as their high-redshift massive counterparts and less than half the size of similarly massive systems at z~0. We use the completeness-corrected numbers of BOSS compacts to compute lower limits on their number densities in narrow redshift bins spanning the range of our sample. The abundance of extremely dense quiescent galaxies at 0.2<z<0.6 is in excellent agreement with the number densities of these systems at high redshift. Our lower limits support the models of massive galaxy assembly through a series of minor mergers over the redshift range 0<z<2.2014ApJ...793...39Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/793/39CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/317 : The CFHTLS Survey (T0007 release) (Hudelot+ 2012)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/MNRAS/418/1055 : BOSS morphology of galaxies (Masters+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/793/39https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/793/39http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/793/39https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/793/39https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/793/39http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/793/39GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/793/39/table1 (Spectroscopic Properties of Compact Galaxy Candidates Selected from BOSS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/793/39/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/793/39/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/793/39/table1?GETtext/xml+votable180.050000true113.455137.5053830.0055555555555555566/695 714 4098 4101 4134 4259 4274 4305 4320 4353 4354 4362 4400 4427 4450 4490 4510 4533 4542 4694 4727 4824 4851 4876 5017 5035 5080 5106 5367 5504 5507 5544 5748 5760 5790 5837 5897 5922 6253 6385 6450 6471 6486 6511 6556 6561 6584 6625 6655 7182 7214 7300 8197 8210 8277 8291 8342 8385 8388 8418 8442 8452 8475 8599 8607 8645 8690 8789 8820 9041 9103 9107 9119 9169 9211 9226 9372 9512 9605 9729 9825 9854 9883 9887 9920 10000 10365 10429 10436 10459 10505 10532 10539 10771 10775 10795 10806 10810 10857 10885 11269 17675 17749 17750 17810 18043 18069 18077 18195 18413 18777 18852 18856 19031 19078 19098 19122 25821 25960 25965 26012 26042 26049 26066 26095 26200 26265 26269 26279 26289 26328 26330 26338 26355 26448 26526 26615 26875 26937 26951 27033 27052 27069 27079 27088 27095 27098 27120 27190 27205 27241 27323 27327 27368 27375 27377 27389 27457 27467 27496 27501 27542 27554 27562 27570 27589 27661 27729 27745 27762 27777 27814 27831 27854 27870 28023 28165 28166 28172 28175 28178 28180 28234 31400 31402 31408 31624 31630 31675 31715 45053https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/793/39?format=asciiOpticaldefaultJ/ApJ/793/39/table1Spectroscopic Properties of Compact Galaxy Candidates Selected from BOSSzRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
