ECAP, room 307, Erwin-Rommel-Str 1
Erlangen, 91058 Germany

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 significant pressure component. These magnetic field components can only be detected indirectly, through the signature they leave on various kinds of radiation and particles, observations of which are fitted to…

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 from observations with Suzaku, Chandra, XMM-Newton, and NuSTAR satellites. I will mainly cover results related to particle acceleration and over-ionized plasma in Galactic supernova remnants. I will also talk about…

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…

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…

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…

Cosmic rays between the knee and the ankle Investigations of the energy spectrum as well as the mass composition of cosmic rays in the energy range of PeV to EeV are important for understanding both, the origin of the galactic and the extragalactic cosmic rays. The multi-detector arrangement of KASCADE and its extension KASCADE-Grande was designed for observations of cosmic ray air showers in this energy range. Most important result from KASCADE is the proof that the knee feature at…

Indirect Dark Matter Searches and Cosmic Ray Transport in the Era of AMS The Alpha Magnetic Spectrometer (AMS) is installed on the International Space Station (ISS) since May 2011. AMS is a complex particle detector designed to precisely measure the fluxes of cosmic rays between 0.5 GeV and a few TeV. The physics goals of the experiment include the search for possible signals of dark matter annihilation and hints for primordial antimatter in the fluxes of cosmic rays. As of…

High-energy neutrinos from AGN? With the advent of multi-messenger observatories, neutrino astronomy is turning into a helpful tool to investigate and put limits on the contribution of the known astrophysical objects to the diffuse neutrino background. Active Galactic Nuclei (AGN) have long been suggested among the candidate sources of cosmic high-energy neutrinos. If hadronic processes operate in the AGN jets, a lot can be learnt by combining neutrino observations with the putative accompanying electromagnetic information. This is motivated by the…

Exploring extreme states of matter with an ultra-bright X-ray free-electron laser In this talk, we will review recent progress in high-energy density physics using the world’s brightest X-ray source, the Linac Coherent Light Source, SLAC's free electron X-ray laser. These experiments investigate laser-driven matter in extreme conditions where powerful X-ray scattering and imaging techniques have been applied to resolve ionic interactions at atomic (Ångstrom) scale lengths and to visualize the formation of dense plasma states . The major research areas…

The VO And Why It Matters To You In the most technical words, the Virtual Observatory (VO) is an effort to enable uniform and efficient access to astronomical data. With more glitz, it is like the Web and Google, only for data. In this talk I will try to convince you that what sounds tedious and boring in reality is exciting and useful to your research. Thus, after some motivation filling in the gaps in the above definitions, I will…
