Information field theory – turning data into images

Charting the Universe from measurements is a challenging information theoretical problem. The finite data provided by instruments is never able to constraint the infinite degrees of freedom of the physical fields we are interested in astronomy or other areas. Additional information like physical laws and empirical correlations has to be folded into the field inference. Information field theory (IFT) is information theory for field inference enabling the
consistent fusion of measurement data and theoretical concepts exploiting techniques developed for quantum field theory. IFT provides optimal methods to generate images exploiting all available information. Existing applications of IFT in astrophysics are galactic tomography, gamma- and radio- astronomical imaging, and the analysis of cosmic microwave background data. Applications in preparation are inferring the dynamics of an observed field and the fusion of measurements from complementary instruments into coherent pictures.

HyperKamiokande: a next generation long baseline neutrino experiment in Japan

The seminar will present the HyperKamiokande (HyperK) project which will build a large volume water Cerenkov detector for long baseline neutrino oscillation studies in Japan. A brief historical resume of the discovery of neutrino oscillations will be provided. The presentation will give an overview of the design of the HyperK detector and its main technical features. Details of the scientific programme to be undertaken will also be discussed. The prospects for the project to determine fundamental measurements such as CP violation and mass hierarchy will also be presented.

Radio detection of ultra-high energy neutrinos

High energy neutrino astronomy is a powerful tool to study the high-energy universe. Neutrinos can escape dense source environments and point back to their sources with sub-degree accuracy. In particular, multi-messenger analyses that combine neutrino detection with electromagnetic (e.g. gamma ray) and gravitational-wave observations bear huge potential to probe the sources of neutrinos and cosmic rays. The detection of neutrinos is challenging because of their small flux and cross-section, and requires the instrumentation of huge volumes. Ultra-high energy neutrinos (E > 1e16 eV) can be efficiently measured using the radio technique, and the cold Antarctic ice is an optimal target material.

Before discussing the radio detection of neutrinos, I will briefly present the radio detection of cosmic rays, highlighting what we can learn from this mature field for neutrino detection. Then, I will report on the pilot neutrino detectors installed on the Ross ice shelf and at the South Pole, discuss how neutrinos can be measured with a radio detector and how their properties can be reconstructed from the short radio flash. At the end, I will present plans for a large-scale radio neutrino detector and discuss its prospects.
