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

3D core-collapse supernova modeling and applications to Cas A and other supernova remnants First three-dimensional, first-principle simulations of core-collapse supernovae have become possible in the recent past. They demonstrate the basic viability of the neutrino-driven mechanism for powering the explosions of the majority of supernova progenitors. Although a number of open questions remain to be settled, the explosion models are now sufficiently mature to strive for detailed comparisons against observations, for example considering well studied, nearby supernovae and young supernova…

Latest results from the AMS experiment on the International Space Station The Alpha Magnetic Spectrometer (AMS) is a detector designed for precision spectroscopy of cosmic rays that was installed on the International Space Station in May 2011. With dimensions of 5x4x3 cubic meters and a weight of 7.5 tons, AMS is the largest cosmic-ray spectrometer ever built. I will summarize the results from the first 6.5 years of operation of AMS. The energy spectra of positrons, electrons, anti-protons, and light…

Radiation Protection Dosimetry: Phantoms and measuring quantities In this talk the concept of the radiation protection quantities will be explained. An overview about the different types and different applications of phantoms in radiation protection and their use for the definition of the different quantities is used for this. The phantoms can serve as a basis for the current definition and the calculation of conversion coefficients for the protection quantities according to ICRP 116. For the definition, the ICRU tissue 4-element…

Reconstructing the origin of the Local Bubble and Loop I via radioisotopic signatures on Earth Deep-sea archives all over the world show an enhanced concentration of the radionuclide 60Fe, isolated in layers dating from about 2.2Myr ago. Since this comparatively long-lived isotope is not naturally produced on Earth, such an enhancement can only be attributed to extraterrestrial sources, particularly one or several nearby supernovae in the recent past. It has been speculated that these supernovae might have been involved in…

The XMM-Newton surveys of the Magellanic Clouds Using the XMM-Newton observatory, we performed X-ray surveys of the Magellanic Clouds, the two star-forming galaxies nearest to the Milky Way. The images obtained from the EPIC instruments provide a wealth of information about the X-ray source populations in the Small and Large Magellanic Cloud. Due to their proximity we can resolve the emission from supernova remnants, and we have discovered many new X-ray binaries powered by accretion of matter. In particular the…

Status of Astronomy in East Africa: Focus on Uganda Astronomy and Cosmology are science disciplines that give an in-depth description and analysis of the structures and forms that characterize the universe. Although Astronomy and Cosmology are not yet fully developed in the East African region, several affirmative developments have been registered in the establishment of the disciplines in the region. These include, among others: postgraduate training of students from Uganda, Kenya, Rwanda and Ethiopia in South Africa since 2003, benefiting…

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 tidal disruption events, low-luminosity gamma-ray bursts and supernovae. Combining neutrino data with electromagnetic measurements in a multi-messenger approach will increase the sensitivity to identify other neutrino sources and help to…
