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


particle collisions revisited

In 2009 it was calculated that, amazingly, particle collisions close to the event horizon of a black hole can generate infinitely high energies under specific circumstances. 
In two new publications my co-authors and I revisited this phenomena. We slightly modified the usual scenario and demonstrated that  it is possible to relax one of the classical requirements for infinite energy. However, it comes at a cost: at least multiple collisions are necessary, or the scenario might not be physically feasible at all. More research  on this topic is necessary!

new research grant

The German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) approved our Collaborative Research Center 'TerraQ - Relativistic and Quantum-based Geodesy'. Starting in January 2021, more than 30 scientists and 25 new PhD students will work on the 17 research projects.

I serve in TerraQ as Principal Investigator for the project C03 'Relativistic Geodesy from Space Using Novel Measurement Concepts'.  More details will soon be available on our website!

trusted reviewer

Peer review is indespensible to ensure the high quality of scientific publications. IOP Publishing now recognized my longstanding reviewer activity by awarding me the Trusted Reviewer status. The journals of IOP include e.g. 'Classical and Quantum Gravity' and the 'Journal of Physics' series.
In total, I completed more than 80 reviews for several different journals, including Science, Physical Review Letters, Physical Review D, and many more. Already in 2018, I was recognized as Distinguished Referee by the European Physical Journal. I am delighted that my review activites are honored again by IOP.


A big step forward: I received my habilitation! Based on an habilitation thesis, an assessment of my teaching skills, and a scientific presentation the physics department of Bremen University unanimously certified my independent and throughout research and lecturing experience in the area of theoretical physics. I am now "Privatdozent", with the venia legendi and the right to officially supervise PhD students. Next destination: Professorship!
