The increased sensitivity of the LIGO and Virgo detectors has opened the possibility for regular detections of EM transient events from mergers of stellar remnants. Gravitational wave sources are expected to have sky localization up to a few hundred square degrees, thus Gaia as an all-sky multi-epoch photometric survey has the potential to be a good tool to search for the EM counterparts. In this paper, we study the possibility of detecting EM counterparts to gravitational wave sources using the Gaia Science Alerts system. We develop an extension to current used algorithms to find transients and test its capabilities in discovering candidate transients on a sample of events from the observation periods O1 and O2 of LIGO and Virgo. For the gravitational wave events from the current run O3, we expect that about 16 (25) per cent should fall in sky regions observed by Gaia 7 (10) d after gravitational wave. The new algorithm will provide about 21 candidates per day from the whole sky.2020MNRAS.493.3264Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/493/3264CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/493/3264https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/493/3264http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/493/3264https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/493/3264https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/493/3264http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/493/3264GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/493/3264/tablea1 (Candidate transients from Gaia)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/3264/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/3264/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/3264/tablea1?GETtext/xml+votable180.050000true57.77567306-59.139923890.0055555555555555565/132 2759 2765 2770 2776 4400 4406 6577 6579 6582 6588 8356 6/141 146 152 154-155 158-159 165 167 173 175-176 179 182-183 186 188-189 229 424 430 517 532-534 579 584-585 597 602 607 1924 11035 11056-11057 11059 11065 11067-11069 11071 11084 11086 11108 11112-11114 11153 11155-11158 17469-17471 17514-17515 17553 17556 17559 17604 17606 17609 17613 17619 19051 26219 26221-26223 26234 26305 26307 26322 26341 26343 26358 26360 26364 31233 31264 31384-31385 33182 33201 33214 33227 33260 33302 33332 33337 33339-33340 33409 33412-33413 33415 33420 33422-33423 33428 33432 33441-33442 44386 44507 44893 45174-45175 45179-45180 45182 45265-45268 45301 45322 45326-45327 45335-45336 45340-45342 45346 45348 45355 45359 45365 45367 45372 45378-45379 45384 45440 45450 45453 45464 45466-45467 45473 45477 45481 45488 45653 458241.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/493/3264?format=asciiOpticaldefaultJ/MNRAS/493/3264/tablea1Candidate transients from GaiarecnoRecord number assigned by the VizieR team.
