A subset of them host kiloparsec-scale, >1000km/s outflows and have little indication of AGN activity, suggesting that extreme star formation can be a primary driver of large-scale feedback. The aim for this paper is to calculate their space density so we can place them in a better cosmological context. We do this by empirically modeling the stellar populations of massive, compact starburst galaxies. We determine the average timescale on which galaxies that have recently undergone an extreme nuclear starburst would be targeted and included in our spectroscopically selected sample. We find that massive, compact starburst galaxies targeted by our criteria would be selectable for ~148_-24_^+27^Myr and have an intrinsic space density n_CS_~1.1_-0.3_^+0.5^x10^-6^/Mpc^3^. This space density is broadly consistent with our z~0.5 compact starbursts being the most extremely compact and star-forming low-redshift analogs of the compact star-forming galaxies in the early universe, as well as them being the progenitors to a fraction of intermediate redshift, post-starburst, and compact quiescent galaxies.2022AJ....164..222Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/222CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/267 : The SDSS Photometric Catalog, Release 4 (Adelman-McCarthy+, 2006)J/ApJ/588/218 : i*g* photometry of SDSS EDR galaxies (Abraham+, 2003)J/ApJ/720/723 : Compact galaxies in the local universe (Taylor+, 2010)J/A+A/528/A35 : Infrared luminosity in GOODS fields (Magnelli+, 2011)J/ApJ/768/74 : PHIBSS; CO observations star-forming galaxies (Tacconi+, 2013)J/ApJ/833/19 : 0.02<z<1.4 poststarburst SDSSgalaxies (Pattarakijwanich+, 2016)J/ApJ/849/53 : Composite SEDs of type 1 and type 2 QSOs (Hickox+, 2017)J/ApJ/862/2 : Post-starburst galaxy ages from SDSS (French+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/222https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/222http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/222https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/222https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/222http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/222GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/164/222/tablea1 (Properties for the galaxies in our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/222/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/222/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/222/tablea1?GETtext/xml+votable180.050000true153.750.06666670.0055555555555555566/4108 4117 4206 4291 4316 4414 4430 4471 4576 4750 4858 4879 4895 4985 4992 5030 5059 5273 5281 5367 5454 5519 5544 5746 5779 5783 5900 5961 6052 6108 6508 6536 6607 6976 7255 7345 7366 7521 8334 8444 8509 8586 8750 8761 8841 8853 8937 8973 9084 9198 9209 9350-9351 9806 9825 9836 10020 10122 10715 10775 10793 10863 10901 10919 11036 11089 11249 11297 11368 11393 11425 11493 11505 11912 12553 18690 19111 19994 20011 21969 25934 25968-25969 25989 26019 26284 26293 26302 26353 26363 26976 27028 27110 27225 27459 27572 27717 27815 27901 28003 28010 28163 28209 28487 31412 31735 32488 32510 32683 36810 490193.830199579824256e-20 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/164/222?format=asciiOpticalInfrareddefaultJ/AJ/164/222/tablea1Properties for the galaxies in our sampleSDSSSDSS identifiermeta.id;meta.maincharMass[10.3/11.8] log Stellar mass (1)log(solMass)phys.massfloate_Mass[0.06/0.7] Error on Masslog(solMass)stat.error;phys.massfloatumag[19/26.6] SDSS u-band AB magnitudemagphot.mag;em.opt.Ufloatgmag[15.8/21.3] SDSS g-band AB magnitudemagphot.mag;em.opt.Vfloatrmag[14.6/20.2] SDSS r-band AB magnitudemagphot.mag;em.opt.Rfloatimag[16.6/19.5] SDSS i-band AB magnitudemagphot.mag;em.opt.Ifloatzmag[16.5/20.7] SDSS z-band AB magnitudemagphot.mag;em.IR.NIRfloatW1mag[14.1/16.2] WISE W1-band Vega magnitudemagphot.mag;em.IR.3-4umfloatW2mag[13.4/16.1] WISE W2-band Vega magnitudemagphot.mag;em.IR.4-8umfloat_RAPosition from SDSS name (right ascension part)degpos.eq.ra;meta.main_DEPosition from SDSS name (declination part)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
