One century after its formulation, Einstein's general relativity (GR) has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests probe the theory…
New nonuniform black string solutions
- B. Kleihaus, J. Kunz, E. Radu
- Physics
- 15 March 2006
We present nonuniform vacuum black strings in five and six spacetime dimensions. The conserved charges and the action of these solutions are computed by employing a quasilocal formalism. We find…

- 15 August 2011
This work constructs traversable wormholes in dilatonic Einstein-Gauss-Bonnet theory in four spacetime dimensions, and demonstrates linear stability with respect to radial perturbations for a subset of these wormholes.
Perturbed black holes in Einstein-dilaton-Gauss-Bonnet gravity: Stability, ringdown, and gravitational-wave emission

Gravitational waves emitted by distorted black holes\char22{}such as those arising from the coalescence of two neutron stars or black holes\char22{}carry not only information about the corresponding…
Rotating boson stars and Q-balls
- B. Kleihaus, J. Kunz, Meike List
- Physics
- 29 May 2005
We consider axially symmetric, rotating boson stars. Their flat-space limits represent spinning Q-balls. We discuss their properties and determine their domain of existence. Q-balls and boson stars…
Analytic solutions of the geodesic equation in higher dimensional static spherically symmetric spacetimes

The complete analytical solutions of the geodesic equation of massive test particles in higher dimensional Schwarzschild, Schwarzschild-(anti)de Sitter, Reissner-Nordstroem and…
Pathway to the Square Kilometre Array - The German White Paper -
- F. Aharonian, T. Arshakian, M. Zwaan
- Physics
- 16 January 2013
The Square Kilometre Array (SKA) is the most ambitious radio telescope ever planned. With a collecting area of about a square kilometre, the SKA will be far superior in sensitivity and observing…
Modified gravity from the quantum part of the metric
- V. Dzhunushaliev, V. Folomeev, B. Kleihaus, J. Kunz
- Physics
- 1 December 2013
It is shown that if a metric in quantum gravity can be decomposed as a sum of classical and quantum parts, then Einstein quantum gravity looks approximately like modified gravity with a nonminimal…
