This\u003Cbr \/\u003E study is a model independent search for directional and temporal correlation between 856\u003Cbr \/\u003E gamma-ray bursts (GRBs) and the astrophysical neutrino flux observed by IceCube. Nearly\u003Cbr \/\u003E 10,000 expanding time windows centered on the earliest reported time of the burst were\u003Cbr \/\u003E examined. The time windows start at \u00b110 s and extend to \u00b115 days. We find no evidence\u003Cbr \/\u003E of correlations for these time windows and set an upper limit on the fraction of the astro-\u003Cbr \/\u003E physical flux that can be attributed to the observed GRBs as a function of the time window.\u003Cbr \/\u003E GRBs can contribute at most 12% of the astrophysical neutrino flux if the neutrino-GRB\u003Cbr \/\u003E correlation time is less than \u224820 hours, and no more than 38% of the astrophysical neutrino\u003Cbr \/\u003E flux can be attributed to the known GRBs at time scales up to 15 days. We conclude that\u003Cbr \/\u003E GRBs observable by satellites are not solely responsible for IceCubes astrophysical neutrino\u003Cbr \/\u003E flux, even if very long correlation time scales are assumed.\u003C\/p\u003E\u003Cp\u003E \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"SEARCH FOR HIGH ENERGY GRB NEUTRINOS IN ICECUBE"}],"uid":"27707","created_gmt":"2015-04-20 12:48:34","changed_gmt":"2016-10-08 02:11:46","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-05-05T16:00:00-04:00","event_time_end":"2015-05-05T18:00:00-04:00","event_time_end_last":"2015-05-05T18:00:00-04:00","gmt_time_start":"2015-05-05 20:00:00","gmt_time_end":"2015-05-05 22:00:00","gmt_time_end_last":"2015-05-05 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"1366","name":"defense"},{"id":"1808","name":"graduate students"},{"id":"913","name":"PhD"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
