我们利用冰立方中微子观测站（2008年4月至2009年5月）“IC40”40串操作期间探测到的北半球中微子的公共数据库，对6个明亮的北方blazar进行了与耀斑通量相关的高能（约1 TeV）中微子的目标搜索。我们的六个目标耀变体是VERITAS TeV γ射线天文台长期监测活动的对象。我们使用公开可用的VERITAS光曲线来确定过量和燃烧的发射周期。相对于在这些能量中占主导地位的近各向同性大气中微子背景的泊松波动，这些预定义的间隔充当了我们寻找中微子过剩的“活动时间窗口”。在定义了优化搜索的参数之后，我们在实际数据中测试多余的中微子之前，用蒙特卡罗模拟确认了预期的泊松行为。我们进行了两次搜索：一次是在IC40运行期间与Mrk 421的明亮耀斑相关的过量中微子，另一次是与其他五个耀变体（Mrk 501, 1ES 0806+524, 1ES 1218+304, 3C 66A和W Comae）最亮的发射周期相关的过量中微子，这些耀变体都比Mrk 421的耀斑暗得多。我们发现，在选定的时间窗口内，来自预定耀变体方向的中微子没有明显过量。我们从每次搜索中得出预期通量相关中微子数量的90%置信度上限。这些极限与先前的点源搜索和费米GeV通量相关搜索一致。我们的上限足够接近物理上有趣的状态，因此我们预计，未来使用已经收集的数据进行分析，要么会限制模型，要么会发现第一个与耀焰相关的高能中微子。
We present a targeted search for blazar flux-correlated high-energy ( ≳ 1 TeV) neutrinos from six bright northern blazars, using the public database of northern hemisphere neutrinos detected during “IC40” 40-string operations of the IceCube neutrino observatory (2008 April to 2009 May). Our six targeted blazars are subjects of long-term monitoring campaigns by the VERITAS TeV γ-ray observatory. We use the publicly available VERITAS light curves to identify periods of excess and flaring emission. These predefined intervals serve as our “active temporal windows” in a search for an excess of neutrinos, relative to Poisson fluctuations of the near-isotropic atmospheric neutrino background, which dominates at these energies. After defining the parameters of an optimized search, we confirm the expected Poisson behavior with Monte Carlo simulations prior to testing for excess neutrinos in the actual data. We make two searches: one for excess neutrinos associated with the bright flares of Mrk 421 that occurred during the IC40 run, and one for excess neutrinos associated with the brightest emission periods of five other blazars (Mrk 501, 1ES 0806+524, 1ES 1218+304, 3C 66A, and W Comae), all significantly fainter than the Mrk 421 flares. We find no significant excess of neutrinos from the preselected blazar directions during the selected temporal windows. We derive 90% confidence upper limits on the number of expected flux-associated neutrinos from each search. These limits are consistent with previous point-source searches and Fermi GeV flux-correlated searches. Our upper limits are sufficiently close to the physically interesting regime that we anticipate that future analyses using already-collected data will either constrain models or yield discovery of the first blazar-associated high-energy neutrinos.
