Your positin at a glance
The successful applicant will be part of the Emmy Noether Research Group at ITP, which, under the leadership of Dr Guillem Domenech, is engaged in "researching the early universe with gravitational waves". The group is part of the "String Theory, Gravitation and Particle Physics" division, which currently consists of three other research groups led by Prof. Giulini (formal aspects of gravitation), Prof. Lechtenfeld (string and quantum field theory) and Prof. Fuchs (particle physics beyond the Standard Model).

The Emmy Noether Group also maintains regular contact with the Max Planck Institute for Gravitational Physics in Hanover, also known as the Albert Einstein Institute (AEI), which is located next to the ITP. The AEI in Hanover is very active in gravitational wave physics, both in the field of pulsar timing arrays and in the field of gravitational wave interferometers (LVK, LISA and ET). In particular, there is the "Observational Relativity and Cosmology" group led by Prof. Allen and the "Binary Merger Observations and Numerical Relativity" group led by Dr Ohme. A new branch of research on high-frequency gravitational wave detectors led by Dr Ejlli has interesting applications for cosmic sources. The work includes the publication of articles and scientific lectures.
Who are we looking for?
A prerequisite for employment is a completed scientific university degree in physics. The doctoral candidate will work on the cosmology of Yukawa interactions in the very early universe, the possible formation of compact objects in the radiation-dominated universum, and the associated gravitational wave signatures. Prior knowledge of cosmology, general relativity theory or gravitational physics is an advantage.
Good communication skills in English, good presentation skills, programming skills, an open attitude towards constructive teamwork and a willingness to travel to conferences or workshops are expected.
