Surface temperature of an accretion disk around a wormhole Kerr-mimicker
A. Karakonstantakis, W. Kluźniak
It has been suggested that spinning wormholes may mimic Kerr black holes in astronomical sources such as X-ray binaries and supermassive compact objects in centers of galaxies. Wit…

General Relativistic Magnetohydrodynamic Simulations of Accreting Tori: Resolution Study
Angelos Karakonstantakis, Debora Lančová, Włodek Kluźniak +1
We present two-dimensional general relativistic radiative magnetohydrodynamical simulations of accretion disks around non-rotating stellar-mass black hole. We study the evolution o…
