SUMMARY:Towards EeV neutrino astronomy with GRAND\, Physics Department
  Colloquium\, Kumiko Kotera \, Institut d'astrophysique de Paris
DESCRIPTION:We are living exciting times: we are now able to probe the
  most violent events of the Universe with diverse messengers (cosmic r
 ays\, neutrinos\, photons and gravitational waves). One challenge to c
 omplete the multi-messenger picture resides in the highest energies\, 
 as no ultra-high energy neutrinos\, with energy > 10^17 eV\, have been
  observed yet. This challenge could be undertaken by the GRAND (Giant 
 Radio Array for Neutrino Detection) project. GRAND is a proposal for a
  large-scale array of self-triggered radio antennas. It stands out tod
 ay as a unique experiment which plans to reach ambitious sensitivity a
 nd sub-degree angular resolution to launch multi-messenger astronomy a
 t ultra-high-energies. A design has been proposed for the GRAND detect
 or\, and the instrumentation is being tested and optimized with 3 smal
 l-scale prototypes: GRAND@Nançay\, GRAND@Auger\, and GRANDProto300. B
 ased on these pathfinders\, the GRAND Collaboration is starting to exp
 lore improved GRAND technical designs for the next large-scale phase o
 f the project. This will consist in two arrays of 10'000 km2 each\, in
  the Northern and Southern hemispheres to be deployed from 2028. In th
 is talk\, we will present the status of the GRAND prototypes\, the pre
 liminary designs and simulation results for the next stages\, and the 
 rich research program that these will enable.
