Twisted doughnuts: Thick disk torus around equatorial asymmetric black hole
Che-Yu Chen, Eva Hackmann, Audrey Trova
The Kerr black hole spacetime is symmetric with respect to a well-defined equatorial plane. When such a symmetry is broken, for instance, by some putative effects beyond general re…
General orbital perturbation theory in Schwarzschild space-time
Oleksii Yanchyshen, Eva Hackmann, Claus Lämmerzahl
We derive general relativistic Gaussian equations for osculating elements for orbits under the influence of a perturbing force without any restrictions in an underlying Schwarzschi…
Null integrability and photon phenomenology in the accelerated Schwarzschild black hole
Shokoufe Faraji, Eva Hackmann
Uniformly accelerated black holes provide a controlled setting to isolate how translatory acceleration and conical defects modify photon dynamics and observable optics. We analyse…
General Relativity and Geodesy
Eva Hackmann, Moritz Huckfeldt, Claus Lämmerzahl +2
Mass redistribution on Earth due to dynamic processes such as ice melting and sea level rise leads to a changing gravitational field, observable by geodetic techniques. Monitoring…
Gravitomagnetic Clock Effect: Using GALILEO to explore General Relativity
Jan Scheumann, Dennis Philipp, Sven Herrmann +5
All experiments to date are in remarkable agreement with the predictions of Einstein's theory of gravity, General Relativity. Besides the classical tests, involving light deflectio…
General Relativistic Chronometry with Clocks on Ground and in Space
Dennis Philipp, Eva Hackmann, Jan P. Hackstein +1
One of the main tasks of geodesy is to determine the gravity field of the Earth from measurements performed on ground and in space. High-precision clock comparison has the potentia…
