On Monday, June 26, 2023, at 12:00 p.m. c.t., the next meeting of our Physics Colloquium will take place.
The speaker will be Prof. Dr. Anna Nelles (DESY Zeuthen, Erlangen) on "Building Radio Detectors to Search for Astrophysical Neutrinos.".
The cosmos manages to accelerate particles to energies that are unattainable for man-made accelerators, ultra-high energy cosmic rays. The source in which this happens have been elusive. The arrival directions of these cosmic rays do not point back to their sources, due to their bent trajectories in (extra-)galactic magnetic fields. Their neutral counterpart, the neutrinos, do reveal the sources, however, they require massive volumes to be detected. In particular, at energies of EeV, which correspond to the highest energy cosmic rays. This talk will introduce you to the Radio Neutrino Observatory in Greenland (RNO-G), the world's largest neutrino detector, currently under construction.
We will walk through science case, experimental challenges, and first data. With being a mid-scale experiment, RNO-G is also a stepping stone towards IceCube-Gen2, which will be built on the successful first detection of the astrophysical neutrino flux by IceCube.
Abstract of the presentation by Dr. Nelles.
The introduction will be given by Prof. Dr. Anna Franckowiak.
The faculty cordially invites all interested parties. The event will take place in lecture hall HNB and hybrid via Zoom. Before the colloquium we offer coffee and cookies.
