Institutskolloquium

Where do most black holes in the Universe come from?

Institutskolloquium
  • Datum: 01.12.2023
  • Uhrzeit: 10:30 - 12:00
  • Vortragender: Prof. Dr. Hans-Walter Rix
  • Hans-Walter Rix is director at the Max-Planck-Institute for Astronomy (MPIA) and professor at the University of Heidelberg faculty for physics and astronomy. In his thesis work with Simon White he figured out that most large elliptical galaxies also have sizable stellar disks, and hence must have a different formation history than thought at the time. He also had the opportunity to work with Craig Hogan on gravitational lensing, with Marcia and George Rieke on infrared imaging and spectroscopy, and with Rob Kennicutt. He then went on to the Institute for Advanced Studies in Princeton, working on some of the very first Hubble Space Telescope data on gravitational lensing and giving in to the numerous, exciting scientific diversions that Princeton has to offer. After a year at MPA, Garching and three years on the faculty at the University of Arizona, he came to MPIA late 1998. In the first five years, his focus was on galaxy evolution, helping to draw up a comprehensive picture of what the population of galaxies looked like when the Universe was half its age. In recent years he has focused his research on our very own galaxy, the Milky Way, because the intricate detail in which it can be studied, should lead us to a better understanding of galaxy formation as a whole. As of 2016, the Gaia space mission along with other vast spectroscopic surveys of stars, and then Hubble's successor James Webb Space Telescope are the next beacons on his science path.

Energy systems of the future, including in particular nuclear fusion

Institutskolloquium
A step by step walk into the energy future: The next hundred years will see major changes in the energy system. The emergence of new technologies and the improvement of existing ones, in interaction with regulation, demand and overall political constraints, will shape the new system. For the time being, it is only possible to identify trends that could lead to change in the future, and to identify technological and other challenges for different system developments, without picking winners now. It is very likely that we will see more renewable energy systems being deployed, but advanced fossil fuel and nuclear technologies will be added depending on political and geographical conditions. The talk will present a three-step view of the future, starting with the current trends that will have the greatest impact in the new future, moving to a time when at least policy targets expect net zero emissions, and then to a very distant outlook when an even more holistic set of sustainability criteria is applied. The presentation tries to show that fusion could be a cornerstone in a future system that reduces more and more compromises on sustainability criteria. [mehr]
