cds-question@unistra.frsurveysastrometrygalaxiescatalogsContext: This study has been developed in the framework of the computational simulations that are executed for the preparation of the ESA Gaia astrometric mission. Aims: We focus on describing the objects and characteristics that Gaia will potentially observe without taking into consideration instrumental effects (detection efficiency, observing errors). Methods: The theoretical Universe Model prepared for the Gaia simulation has been statistically analysed at a given time. Ingredients of the model are described, with the greatest emphasis on the stellar content, the double and multiple stars, and variability. Results: In this simulation the errors have not yet been included. Hence we estimated the number of objects and their theoretical photometric, astrometric and spectroscopic characteristics if they are perfectly detected.We show that Gaia will be able to potentially observe 1.1 billion of stars (single or part of multiple star systems) of which about 2% are variable stars and 3% have one or two exoplanets. At the extragalactic level, observations will be potentially composed of several millions of galaxies, half a million to 1 million quasars and about 50,000 supernovae that will occur during the five years of the mission.2012A&A...543A.100Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VI/137CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)https://www.cosmos.esa.int/web/gaia : GAIA Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/137https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/137http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/137https://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/137https://vizier.iucaa.in/viz-bin/votable?-source=VI/137http://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/137GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table VI/137/gum_mw (Gaia Universe Model Snapshot (GUMS): Milky Way stars (among 2,143,475,885 stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/137/gum_mw?https://vizier.iucaa.in/viz-bin/conesearch/VI/137/gum_mw?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/137/gum_mw?GETtext/xml+votable180.050000true45.01461914630.02300810360.005555555555555556Hips catalogue for table VI/137/gum_mwhttps://hipscat.cds.unistra.fr/HiPSCatService/VI/137/gum_mwCone search capability for table VI/137/gum_lmc (Gaia Universe Model Snapshot (GUMS): LMC stars (among 7,559,826 stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/137/gum_lmc?https://vizier.iucaa.in/viz-bin/conesearch/VI/137/gum_lmc?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/137/gum_lmc?GETtext/xml+votable180.050000true75.2913-72.46040.005555555555555556Cone search capability for table VI/137/gum_smc (Gaia Universe Model Snapshot (GUMS): SMC stars (among 1,250,384 stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/137/gum_smc?https://vizier.iucaa.in/viz-bin/conesearch/VI/137/gum_smc?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/137/gum_smc?GETtext/xml+votable180.050000true20.6452-74.90060.005555555555555556Cone search capability for table VI/137/gum_gal (Gaia Universe Model Snapshot (GUMS) (galaxies) (among 37,831,197 sources))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/137/gum_gal?https://vizier.iucaa.in/viz-bin/conesearch/VI/137/gum_gal?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/137/gum_gal?GETtext/xml+votable180.050000true45.01818603940.04231715290.005555555555555556Cone search capability for table VI/137/gum_qso (Gaia Universe Model Snapshot (GUMS) (quasars))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/137/gum_qso?https://vizier.iucaa.in/viz-bin/conesearch/VI/137/gum_qso?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/137/gum_qso?GETtext/xml+votable180.050000true20.16914523-22.491057650.005555555555555556Cone search capability for table VI/137/gum_sn (Gaia Universe Model Snapshot (GUMS (supernovae))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/137/gum_sn?https://vizier.iucaa.in/viz-bin/conesearch/VI/137/gum_sn?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/137/gum_sn?GETtext/xml+votable180.050000true33.133525021459.38645902430.005555555555555556Gaia0/0-11 6/1.9867573869263685e-19 4.621782916333392e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/VI/137?format=asciidefaultVI/137/gum_mwGaia Universe Model Snapshot (GUMS): Milky Way stars (among 2,143,475,885 stars)rBarycentric distance (distance)pcpos.distance;pos.heliocentricfloatrecno[1/2143475885] Original record numbermeta.recordlongIDsource identifier (sourceExtendedId)meta.id;meta.maincharRA2kdegRight ascension ICRS, Epoch=J2000 (G1)degpos.eq.raDE2kdegDeclination ICRS, Epoch=J2000 (G1)degpos.eq.decHostHost galaxy: 1=Milky Way, 2=SMC, 3=LMC (host)meta.codeintPop[1/3]?
