We responded promptly to the gravitational-wave alerts sent by the LIGO and Virgo Collaborations, covering a region of $90$ deg$^2$, $72$ deg$^2$ and $99$ deg$^2$ for GW150914, GW151226 and GW170814 respectively, and kept observing the three areas over nearly two months. The surveys average limiting magnitude reached about 22 mag AB in the $r-$band. For GW170817 event we secured deep observations of AT2017gfo's host galaxy NGC4993. \u0000The paper outlines the VST observational strategy and two independent procedures \u0000developed to search for transient counterpart candidates in multi-epoch VST images. For BBH events, numerous transients have been discovered, mostly variable stars and eclipsing binaries, but no candidates are identified as related to the gravitational-wave events. \u0000For GW170817 event the VST observations allows to measure the optical transient magnitudes at the faint end of the light curve.","PeriodicalId":147125,"journal":{"name":"Proceedings of Gravitational-waves Science&Technology Symposium — PoS(GRASS2018)","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134013342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This marks the first time a binary neutron star merger was detected by the LIGO-Virgo collaboration and that an electromagnetic counterpart to a gravitational wave event has been observed. GRB170817A was detected by the SPI-ACS on-board emph{INTEGRAL} and the emph{Fermi}/GBM instruments ( sim 1.7) s after the GW event. Following the prompt emission, emph{INTEGRAL} performed pointed observations for 5.4 days. During this time the instruments provided stringent upper limits on any electromagnetic signal in the 3 keV to 8 MeV range. Interestingly, the GRB was found to be extremely subluminous.In light of these results from GRB170817A, we have begun analysis of soft gamma-ray data ((200 textrm{ keV } - 2.6 textrm{ MeV })) from emph{INTEGRAL}/PICsIT. With this wide field-of-view instrument, we have begun searching for untriggered SGRBs reported by emph{Fermi}/GBM as well as preparing for real-time analysis during future LIGO-Virgo observing runs.","PeriodicalId":147125,"journal":{"name":"Proceedings of Gravitational-waves Science&Technology Symposium — PoS(GRASS2018)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123094104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
