I am Eva Hackmann, a scientist working on General Relativity, black holes, neutron stars and related stuff.


clocks and space

All physical processes happen in time, and time is everywhere. But how is time at one place related to time at another place? What sounds like a trivial questions, is for highly accurate clocks actually very complicated. For example, heigths and rotations have to be considered!

The German Research Foundation (DFG) now funded the new research unit  "clock metrology" that will tackle these and related questions, that have major impact on the definition of reference frames and, therefore, on the quantization of changes on Earth e.g. due to climate change. I am proud to be part of this research team!

accretion discs

Black holes are often surrounded by matter in the form of a disc, that "feeds" the central black hole, a process known as accretion. In March 2023, we start a new research project funded by the German Research Foundation (DFG) to study the influence of electromagnetic interactions in analytical models of such accretion discs. This is, for example, of interest to understand the polarization in the first pictures of black holes, recently published by the Event Horizon Telescope collaboration. I am already excited to see the results!

jury IdeenLauf

The german ministry of education and research celebrates in 2022 the year of science. In this context the 'IdeenLauf' was initiated:  all citizens may formulate research questions and submit them to the website of the intitiative. The aim is to encourage all citizens to participate in future research (-politics). I am honored to serve in the science jury for the area Environment, Climate, Earth, Universe! Looking forward to your questions!
