  <title><![CDATA[IceCube neutrino analysis pegs possible galactic source for cosmic rays]]></title>
  <body><![CDATA[<p>Scientists with the&nbsp;<a href="https://icecube.wisc.edu/science/icecube">IceCube</a><a href="https://icecube.wisc.edu">&nbsp;Neutrino Observatory</a>&nbsp;in Antarctica&nbsp;have now analyzed a decade&#39;s worth of such neutrino detections and discovered evidence that an active galaxy called&nbsp;<a href="https://en.wikipedia.org/wiki/Messier_77">Messier 77</a>&nbsp;(aka the Squid Galaxy) is a strong candidate for one such high-energy neutrino emitter, according to a&nbsp;<a href="http://www.science.org/doi/10.1126/science.abg3395">new paper</a>&nbsp;published in the journal <em>Science</em>. It brings astrophysicists one step closer to resolving the mystery of the origin of high-energy cosmic rays. The IceCube&nbsp;international collaboration of scientists includes <a href="https://physics.gatech.edu/user/ignacio-taboada">Ignacio Taboada</a>, professor in the <a href="https://physics.gatech.edu">School of Physics</a> who also serves as IceCube&#39;s spokesperson.
