  I will review the processes of making the elements in various astrophysical environments, emphasizing the role of fundamental physics and observational evidence. I then discuss how to understand chemical evolution from both the ab initio and the data-driven approaches, contrasting the respective central issues. To illustrate the latter approach, I show how the average patterns of heavy element production via rapid neutron capture, the r-process, can be inferred from the data on old stars in the Milky Way and how they can inform us about the conditions of the underlying astrophysical sources and the nuclear systematics governing the r-process.

  Seminar of the institute

• Simulating the transient sky

  Monday 8 June, 12:00 - 18:00 PM, Abbeanum, SR 102
  
  A central goal of the workshop is to highlight key open questions in the field: What are the dominant mechanisms shaping electromagnetic counterparts of mergers? How do microphysical processes—such as neutrino transport, magnetic field amplification, and radiation transfer—impact observable signatures? What limits current simulations, and how can they be overcome to achieve predictive power across scales? By addressing these challenges, the workshop aims to foster collaboration and identify promising directions for the next generation of transient sky modeling.

• Prof. Dr. Marika Taylor - The black hole information paradox

   de

  Monday 22 June, 4:15 - 5:45 PM, Abbenaum, HS 1
  
  Fifty years ago, Stephen Hawking showed that black holes emit radiation due to quantum effects. The discovery of Hawking radiation has led to a longstanding puzzle about the nature of black holes. This is the information paradox, the question of what happens to information that falls into a black hole. In this colloquium we will explain the information paradox, and discuss why it is so important for understanding the quantum nature of gravity. We will explore contemporary ideas for resolving the paradox, and how these may relate to quantum computing.

• Prof. Klaus Blaum - Present and future of experimental low-energy precision nuclear physics

  Monday, 29. June, 4:00 - 6:00 PM Abbenaum, HS 1
  
  The four fundamental interactions and their underlying symmetries, together with the fundamental constants and intrinsic properties of elementary particles, such as nuclear masses and magnetic moments, constitute the structural foundation of the universe and underpin the well-established Standard Model of particle physics.
  This overview presents recent nuclear-physics tests of these interactions and symmetries through high-precision measurements of atomic and nuclear masses, nuclear charge radii, and magnetic moments. These experiments are performed on single or few cooled exotic ions, either probed by laser spectroscopy or confined in Penning traps.
  Notably, such measurements have, among other achievements, enabled stringent constraints to be placed on a hypothetical fifth force in the keV/c² to MeV/c² mass range coupling to electrons and neutrons, and have significantly improved the precision of several key fundamental constants.
