Physics & Astronomy Colloquium
February 8 @ 3:45 pm - 5:00 pm
Speaker: Dr. John Felde (University of Maryland)
Title: The Era of High Energy Neutrino Astronomy with IceCube
Abstract: The IceCube Neutrino Observatory, located at the geographic south pole, is the largest neutrino telescope ever built. IceCube has recently discovered a diffuse astrophysical neutrino signal that will provide a unique perspective into the high-energy universe for years to come. So far, however, IceCube has been unable to identify any specific classes of objects as the dominant producers of the observed astrophysical neutrinos. With this goal in mind, IceCube, along with the greater high-energy astrophysics community, is pursuing a multi-messenger approach in order to maximize the available information. Discovering the sources and mechanisms responsible for hadronic acceleration in the cosmos is vital for our understanding of the universe. Following an overview of the status of neutrino astronomy I will discus the current techniques used to search for neutrino sources and describe our efforts to contribute to multi-messenger programs. Finally, as the community looks to the future, I will describe our plans for an extension of IceCube that will greatly expand the potential for significant discoveries.
The colloquia will be preceded by light refreshments in GL227 from 3:30 – 3:45p.m.
