Abstract

During the Laser Interferometer Gravitational-wave Observatory and Virgo joint science runs in 2009-2010, gravitational wave (GW) data from three interferometer detectors were analyzed within minutes to select GW candidate events and infer their apparent sky positions. Target coordinates were transmitted to several telescopes for follow-up observations aimed at the detection of an associated optical transient. Images were obtained for eight such GW candidates. We present the methods used to analyze the image data as well as the transient search results. No optical transient was identified with a convincing association with any of these candidates, and none of the GW triggers showed strong evidence for being astrophysical in nature. We compare the sensitivities of these observations to several model light curves from possible sources of interest, and discuss prospects for future joint GW-optical observations of this type. ; United States National Science Foundation for the construction and operation of the LIGO Laboratory ; Science and Technology Facilities Council of the United Kingdom ; Max-Planck-Society ; State of Niedersachsen/Germany ; Italian Istituto Nazionale di Fisica Nucleare ; French Centre National de la Recherche Scientifique for the construction and operation of the Virgo detector ; Australian Research Council ; International Science Linkages program of the Commonwealth of Australia ; Council of Scientific and Industrial Research of India ; Istituto Nazionale di Fisica Nucleare of Italy ; Spanish Ministerio de Economia y Competitividad ; Conselleria d'Economia Hisenda i Innovacio of the Govern de les Illes Balears ; Foundation for Fundamental Research on Matter ; Netherlands Organisation for Scientific Research ; Polish Ministry of Science and Higher Education ; FOCUS Programme of Foundation for Polish Science ; Royal Society ; Scottish Funding Council ; Scottish Universities Physics Alliance ; National Aeronautics and Space Administration ; OTKA of Hungary ; Lyon Institute of Origins (LIO) ; National Research Foundation of Korea Industry Canada ; Province of Ontario through the Ministry of Economic Development and Innovation ; National Science and Engineering Research Council Canada ; Carnegie Trust ; Leverhulme Trust ; David and Lucile Packard Foundation ; Research Corporation, FIRB (Italian Ministry of Education, University and Research) RBFR12PM1F ; Alfred P.
