Charged hairy black holes in the gauged Einstein-Friedberg-Lee-Sirlin model

Jutta Kunz, Yakov Shnir

We obtain charged spherically symmetric black holes in the two-component scalar Einstein-Maxwell-Friedberg-Lee-Sirlin model with a symmetry breaking potential. These asymptotically…

Light Ring behind Wormhole Throat: Geodesics, Images and Shadows

Hyat Huang, Jutta Kunz, Jinbo Yang +1

The geodesics of the Ellis-Bronnikov wormhole with two parameters are studied. The asymmetric wormhole has only one light ring and one innermost stable circular orbit located on on…

Phases of rotating black objects in d = 5 Einstein-Gauss-Bonnet theory

Burkhard Kleihaus, Jutta Kunz, Eugen Radu

We consider several different classes of asymptotically flat, rotating black objects in d = 5 Einstein-Gauss-Bonnet (EGB) theory. These are first the black holes with two equal-mag…

Quadrupole instability of static scalarized black holes

Burkhard Kleihaus, Jutta Kunz, Tim Utermöhlen +1

The addition of a Ricci coupling to Einstein-scalar-Gauss-Bonnet theories makes general relativity a cosmological attractor. Previous work considered a quadratic coupling function…

Are slowly rotating Ellis-Bronnikov wormholes stable?

Bahareh Azad, Jose Luis Blázquez-Salcedo, Fech Scen Khoo +1

We investigate the radial perturbations of Ellis-Bronnikov wormholes () in a slowly rotating background expanded up to second order in rotation. We find indications t…

Magnetized Thick Disks around Boson Stars

Kristian Gjorgjieski, Jutta Kunz, Matheus C. Teodoro +2

The effects of magnetic fields on accretion disks around compact objects are of high importance in the study of their general properties and dynamics. Here we analyze the influence…
