Photon rings and shadows of Kerr black holes immersed in a swirling universe

Rogério Capobianco, Betti Hartmann, Jutta Kunz +2

We discuss photon rings around as well as shadows of Kerr black holes immersed in a swirling spacetime (KBHSU). We find that the spin-spin interaction between the angular momentum…

Motion of charged particles in an electromagnetic swirling universe: The complete set of solutions

Rogério Capobianco, Betti Hartmann, Jutta Kunz

We discuss the motion of electrically and magnetically charged particles in the electromagnetic swirling universe. We show that the equations of motion can be decoupled in the Hami…

Geodesic Motion in a Swirling Universe: The complete set of solutions

Rogério Capobianco, Betti Hartmann, Jutta Kunz

We study the geodesic motion in a space-time describing a swirling universe. We show that the geodesic equations can be fully decoupled in the Hamilton-Jacobi formalism leading to…

Horndeski Proca stars with vector hair

Y. Brihaye, B. Hartmann, B. Kleihaus +1

We study Proca stars in a vector-tensor gravity model inspired by Horndeski's generalized Einstein-Maxwell field equations, supplemented with a mass term for the vector field. We d…

A Mission to Explore the Pioneer Anomaly

The Pioneer Explorer Collaboration, H. Dittus, S. G. Turyshev +37

The Pioneer 10 and 11 spacecraft yielded the most precise navigation in deep space to date. These spacecraft had exceptional acceleration sensitivity. However, analysis of their ra…

Dyonic Non-Abelian Black Holes

Y. Brihaye, B. Hartmann, J. Kunz +1

We study static spherically symmetric dyonic black holes in Einstein-Yang-Mills-Higgs theory. As for the magnetic non-abelian black holes, the domain of existence of the dyonic non…
