The Astrophysics of BH-BH/NS-NS Mergers with LIGO/Virgo I will discuss the astrophysical importance of the recent LIGO/Virgo direct detections of gravitational-waves. Despite majority of the expectations, it was not neutron star mergers being detected first, but the series of exotic massive black hole mergers. I will describe the leading theories...
The gravitational wave detection of a binary neutron star merger: expectations, surprises, and prospects On August 17, 2017, Advanced LIGO & Virgo detected gravitational waves from a binary neutron star merger. A short-duration gamma-ray burst was detected in temporal coincidence by the INTEGRAL and Fermi satellites. A few hours later,...
A new era in multi-messenger astronomy With the recent discoveries of gravitational waves and high-energy cosmic neutrinos, we are witnessing the beginning of a new era in Multi-Messenger astronomy. The exploration of the Universe through these new messengers, along with electromagnetic radiation and cosmic rays, provides for new insights into...
Overview of Athena and the Wide Field Imager The Advanced Telescope for High-Energy Astrophysics will be ESA's next large X-ray observatory. While the launch date (2028) seems far, the community has already now been very active in assembling the scientific goals for the Athena and thus the requirements on the...
SVOM - Space-based multiband astronomical Variable Objects Monitor The Chinese-French space mission SVOM (Space-based multi-band astronomical Variable Objects Monitor) is mainly designed to detect and localize Gamma-Ray Burst events (GRBs). The satellite, to be launched late 2021, embarks a set of gamma-ray, X-ray and optical imagers. Thanks to its pointing...
Survival in galaxy clusters: from ultra-diffuse to ultra-compact objects The diversity of low-mass cluster galaxies in terms of their size and stellar content is striking. So-called ultra-diffuse galaxies residing in the core of a massive galaxy cluster appear surprisingly intact and might be protected by a large dark matter content....
Dark matter searches with gamma rays The Fermi Large Area Telescope has during its almost 10 years of mission time revolutionized our understanding of the gamma-ray sky. It enabled, e.g., the discovery of the Fermi bubbles, a surprisingly large number of gamma-ray emitting millisecond pulsars, dark gas in the Milky...
News from the ECAP laboratory Kay Graf and Stefan Funk will report on the status of the ECAP laboratory building.
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...
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...
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...
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...
