cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryredshiftedspectroscopygravitational-wavesOn 2019 August 14, the Advanced LIGO and Virgo interferometers detected the high-significance gravitational wave (GW) signal S190814bv. The GW data indicated that the event resulted from a neutron star-black hole (NSBH) merger, or potentially a low-mass binary BH merger. Due to the low false-alarm rate and the precise localization (23deg^2^ at 90%), S190814bv presented the community with the best opportunity yet to directly observe an optical/near-infrared counterpart to an NSBH merger. To search for potential counterparts, the GROWTH Collaboration performed real-time image subtraction on six nights of public Dark Energy Camera images acquired in the 3 weeks following the merger, covering >98% of the localization probability. Using a worldwide network of follow-up facilities, we systematically undertook spectroscopy and imaging of optical counterpart candidates. Combining these data with a photometric redshift catalog, we ruled out each candidate as the counterpart to S190814bv and placed deep, uniform limits on the optical emission associated with S190814bv. For the nearest consistent GW distance, radiative transfer simulations of NSBH mergers constrain the ejecta mass of S190814bv to be M_ej_<0.04M_{sun}_ at polar viewing angles, or M_ej_<0.03M_{sun}_ if the opacity is {kappa}<2cm^2^g^-1^. Assuming a tidal deformability for the NS at the high end of the range compatible with GW170817 results, our limits would constrain the BH spin component aligned with the orbital momentum to be {chi}<0.7 for mass ratios Q<6, with weaker constraints for more compact NSs.2020ApJ...890..131Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/890/131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/250 : The 2dF Galaxy Redshift Survey (2dFGRS) (2dFGRS Team, 1998-2003)VII/281 : GLADE v2.3 catalog (Dalya+, 2018)J/AJ/108/2128 : RC3 corrections and additions (Corwin+ 1994)J/A+A/562/A73 : ZJ VISTA photometry in NGC253 stellar halo (Greggio+, 2014)J/A+A/593/A68 : PTF12os & iPTF13bvn spectra and light curves (Fremling+, 2016)J/A+A/625/A152 : Light-curve models of black hole (Barbieri+, 2019)J/ApJ/884/L55 : Opt. follow-up of gal. within S190814bv region (Gomez+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/890/131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/890/131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/890/131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/890/131https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/890/131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/890/131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/890/131/table2 (*Subset of candidates discovered or independently detected by the DECam-GROWTH team during the follow-up of S190814bv that were spectroscopically classified)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/890/131/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/890/131/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/890/131/table2?GETtext/xml+votable180.050000true22.26529611-32.7051550.005555555555555556Cone search capability for table J/ApJ/890/131/table3 (*Additional candidates discovered during the follow-up of S190814bv, whose host galaxy redshift is compatible with the LIGO/Virgo distance (2{sigma}))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/890/131/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/890/131/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/890/131/table3?GETtext/xml+votable180.050000true14.51791611-26.083013060.0055555555555555566/16646-16647 16654 16656-16657 16659 16662 16664 16666 16668 16670-16671 16689 16694 35641 35771https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/890/131?format=asciiOpticalInfrareddefaultJ/ApJ/890/131/table2*Subset of candidates discovered or independently detected by the DECam-GROWTH team during the follow-up of S190814bv that were spectroscopically classifiedSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
