The problem of ultracompact rotating gravastars
Mieszko Rutkowski, Andrzej Rostworowski
A number of authors provided arguments that a rotating gravastar is a good candidate for a source of the Kerr metric. These arguments were based on the second order perturbation an…
Master equations and stability of Einstein-Maxwell-scalar black holes
Aron Jansen, Andrzej Rostworowski, Mieszko Rutkowski
We derive master equations for linear perturbations in Einstein-Maxwell-scalar theory, for any spacetime dimension D and any background with a maximally symmetric n = (D - 2)-dimen…
Nonlinear perturbations of Reissner-Nordström black holes
Mieszko Rutkowski
We develop a nonlinear perturbation theory of Reissner-Nordström black holes. We show that, at each perturbation level, Einstein-Maxwell equations can be reduced to four inhomogene…
Einstein clusters as models of inhomogeneous spacetimes
Sebastian J. Szybka, Mieszko Rutkowski
We study the effect of small-scale inhomogeneities for Einstein clusters. We construct a spherically symmetric stationary spacetime with small-scale radial inhomogeneities and prop…
Collisions near Kerr black holes: lower limit of energy between orbiting and incoming particles
Mieszko Rutkowski
In our paper we investigate the lower limit of collisional energy of test particles near the Kerr black hole. In particular we examine the minimal Lorentz factor between the freely…
A spine-sheath model for strong-line blazars
Marek Sikora, Mieszko Rutkowski, Mitchell C. Begelman
We have developed a quasi-analytical model for the production of radiation in strong-line blazars, assuming a spine-sheath jet structure. The model allows us to study how the spine…
Evolutionary tracks of millisecond pulsars with low-mass companions
Filip Ficek, Mieszko Rutkowski, Włodek Kluźniak
We consider the evolution of millisecond radio pulsars in binary systems with a main-sequence or evolved stellar companion. Evolution of non-accreting binary systems with "eclipsin…
