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 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…
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 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…
