The mass density contrast in perturbed Friedman-Lemaitre-Robertson-Walker cosmologies
Edward Malec
We analyze the evolution of the mass density contrast in spherical perturbations of flat Friedman-Lemaitre-Robertson-Walker cosmologies. Both dark matter and dark energy are includ…
Steady critical accretion onto black holes: selfgravity and sonic point characteristics
Patryk Mach, Edward Malec
The spherically symmetric steady accretion of polytropic perfect fluids onto a black hole is the simplest flow model that can demonstrate effects of backreaction (selfgravity). It…
Stationary massive disks around black holes: realistic equation of state and bifurcation
Wojciech Kulczycki, Patryk Mach, Edward Malec
We study stationary and axially symmetric black hole-disk systems, assuming a combination of the DD2 and Timmes-Swesty equations of state and a three-parameter family of rotation l…
On extensions of the Penrose inequality with angular momentum
Wojciech Kulczycki, Edward Malec
We numerically investigate the validity of recent modifications of the Penrose inequality that include angular momentum. Formulations expressed in terms of asymptotic mass and asym…
General-relativistic rotation laws in fluid tori around spinning black holes
Wojciech Kulczycki, Edward Malec
We obtain rotation laws for axially symmetric, selfgravitating and stationary fluids around spinning black holes. They reduce --- in the Newtonian limit --- to monomial rotation cu…
Modelling general-relativistic disk in OJ 287
Wojciech Dyba, Patryk Mach, Edward Malec
We model self-gravitating disks in Keplerian motion around the primary black hole, in the binary black hole system OJ 287 with a torus, employing a consistently general-relativisti…
