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...
Updates of the ECAP desktop computing system New operating system, new hardware and new IT services for the ECAP desktop computing system will be presented and discussed.
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...
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...
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
Primordial Black Holes as Dark Matter Primordial black holes are black holes that may have formed in the early Universe. Their masses potentially span a range from as low as the Planck mass up to many orders of magnitude above the solar mass. This, in particular, includes black holes of...
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...
Prof. Heber will present the FAU contributions to the APPLAUSE digitization project of astronomical photo negative at the Collegium Alexandrinum. More on the project in our News Item and at the Collegium's page.
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...
