Status report on IceCube-Gen2 and eROSITA Gisela Anton and Joern Wilms will give us a brief status report on the IceCube-Gen2 and eROSITA projects.

Fundamental Physics studies with X-ray spectral-timing-polarimetry and the eXTP mission

Searching for electromagnetic counterparts to high-energy neutrinos In September 2017, the detection of a high-energy neutrino in coincidence with a flaring gamma-ray blazar revealed the first compelling high-energy neutrino source candidate. At the same time gamma-ray blazars are disfavored as the dominant neutrino source class. Other plausible source candidates are...

Characterizing the diffuse neutrino flux with the future KM3NeT/ARCA detector

Probing Particle Physics with IceCube The IceCube observatory located at the South Pole is a cubic-kilometre optical Cherenkov telescope primarily designed for the detection of high-energy astrophysical neutrinos. IceCube became fully operational in 2010 and reached a milestone in 2013 by the first observation of cosmic neutrinos in the TeV-PeV...

On the difficulties to derive reliable CNO abundances in hot massive stars Though low in number, massive stars play an essential role in the early and present Universe, due to their enormous energy output and production of metals. Moreover, the end-products of massive star evolution are among the most spectacular...

The Magnetic Field of the Milky Way The Milky Way's magnetic field has coherent structures on Galactic scales, following spiral arms but also Galactic outflows. It also has a turbulent component, which influences the galactic ecosystem in many ways, such as delaying star formation, isotropizing Galactic cosmic rays, and providing...

Recent Results from X-ray Studies of Supernova Remnants X-ray emission from supernova remnants provides us with probes to high energy phenomena such as acceleration of cosmic-ray particles and nucleosynthesis in supernova explosions. In this talk, I will present some of recent results that I, with my students and collaborators, obtained...

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...

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...
