** watch future Linda Hall Library lectures live at new.livestream.com/lindahall ** October 22, 2015, in the Main Reading Room of the Linda Hall Library Dr. Naoko Kurahashi Neilson is an assistant professor of physics at Drexel University About the lecture: The Universe has been studied using light since the dawn of astronomy, when starlight captured the human eye. The IceCube Neutrino Observatory proposes to observe the Universe in a new way, using neutrinos (small elementary particles) as the messenger. IceCube is an enormous observatory that is buried deep under the surface at the geographic South Pole. This talk will explain the extreme astrophysics we study, at extreme energies, in an extreme location. About the speaker: Dr. Naoko Kurahashi Neilson is an assistant professor of physics at Drexel University, where her research interest is in experimental neutrino astroparticle physics. She obtained her Ph.D. by “listening” for very high energy neutrinos that originated from outside our galaxy in the ocean in the Bahamas. She decided that she had had enough of tropical sun, and joined the IceCube experiment, a neutrino observatory operating at the geographical South Pole. There, she is interested in resolving galactic and extragalactic astrophysical sources that emit neutrinos. Her current research focus is to analyze data from the completed IceCube detector to resolve sources spatially, particularly in the southern sky. She has a B.A. in physics from the University of California, Berkeley, and a Ph.D. in physics/applied physics from Stanford University. Video produced by The VideoWorks of Roeland Park, Kansas.
