Construction of vacuum initial data by the conformally covariant split system

Patryk Mach, Yaohua Wang, Naqing Xie

Using the implicit function theorem, we prove existence of solutions of the so-called conformally covariant split system on compact 3-dimensional Riemannian manifolds. They give ri…

Two mass conjectures on axially symmetric black hole--disk systems

Wojciech Kulczycki, Patryk Mach, Edward Malec

We analyze stationary self-gravitating disks around spinning black holes that satisfy the recently found general-relativistic Keplerian rotation law. There is a numerical evidence…

Relativistic Low Angular Momentum Accretion: Long Time Evolution of Hydrodynamical Inviscid Flows

Patryk Mach, Michał Piróg, José A. Font

We investigate relativistic low angular momentum accretion of inviscid perfect fluid onto a Schwarzschild black hole. The simulations are performed with a general-relativistic, hig…

Self-gravitating axially symmetric disks in general-relativistic rotation

Janusz Karkowski, Wojciech Kulczycki, Patryk Mach +3

We integrate numerically axially symmetric stationary Einstein equations describing self-gravitating disks around spinless black holes. The numerical scheme is based on a method de…

Rotating Bowen-York initial data with a positive cosmological constant

Patryk Mach, Jerzy Knopik

A generalization of the Bowen-York initial data to the case with a positive cosmological constant is investigated. We follow the construction presented recently by Bizoń, Pletka an…
