SUMMARY:Discovering the Highest Energy Neutrinos Using a Radio Phased 
 Array\, Physics Department Colloquium\, Abigail Vieregg\, University o
 f Chicago
DESCRIPTION:Ultra-high energy neutrino astronomy sits at the boundary 
 between particle physics and astrophysics. The detection of the highes
 t energy neutrinos would be an important step toward understanding the
  most energetic cosmic accelerators and would enable tests of fundamen
 tal physics at energy scales that cannot easily be achieved on Earth. 
  IceCube has detected astrophysical neutrinos at lower energies\, and 
 at higher energies the best limits to date on the flux comes from IceC
 ube and the ANITA experiment\, a NASA balloon-borne radio telescope de
 signed to detect coherent radio Cherenkov emission from cosmogenic ult
 ra-high energy neutrinos.  The future of high energy neutrino detectio
 n lies with ground-based radio arrays like ARA\, which would represent
  an large leap in sensitivity.  I will discuss a new radio phased arra
 y design that will improve sensitivity enormously and could push the e
 nergy threshold for radio detection down to overlap with the energy ra
 nge probed by IceCube.
