Gravitational collapse involving electric charge in the decoupling limit of the dilatonic Gauss--Bonnet gravity
Anna Nakonieczna, Łukasz Nakonieczny
The paper discusses a collapse of a self-interacting electrically charged scalar field in the decoupling limit of the dilatonic Gauss-Bonnet gravity. The emerging spacetimes were e…
Gravitational dynamics in the Higgs-dark matter sector toy model: the field theoretic perspective
Anna Nakonieczna, Łukasz Nakonieczny
The objective of the paper was to examine gravitational evolutions in the Higgs--dark matter sector toy model. The real part of the Higgs doublet was modelled by a neutral scalar.…
Black hole factory: a review of double-null formalism
Anna Nakonieczna, Łukasz Nakonieczny, Dong-han Yeom
In this review paper, we comprehensively summarize numerical applications of double-null formalism for studying dynamics within the theory of gravity. By using the double-null coor…
Black hole initial data by numerical integration of the parabolic-hyperbolic form of the constraints
Anna Nakonieczna, Łukasz Nakonieczny, István Rácz
The parabolic-hyperbolic form of the constraints is integrated numerically. The applied numerical stencil is order accurate (in the spatial directions) while 'time'-integr…
Dark matter cosmic string in the gravitational field of a black hole
Łukasz Nakonieczny, Anna Nakonieczna, Marek Rogatko
We examined analytically and proposed a numerical model of an Abelian Higgs dark matter vortex in the spacetime of a stationary axisymmetric Kerr black hole. In analytical calculat…
Static configurations and evolution of higher dimensional brane-dilaton black hole system
Anna Nakonieczna, Łukasz Nakonieczny, Rafał Moderski +1
Static configurations and a dynamical evolution of the system composed of a higher-dimensional spherically symmetric dilaton black hole and the Dirac-Goto-Nambu brane were investig…
Scalar field as an intrinsic time measure in coupled dynamical matter-geometry systems. II. Electrically charged gravitational collapse
Anna Nakonieczna, Dong-han Yeom
Investigating the dynamics of gravitational systems, especially in the regime of quantum gravity, poses a problem of measuring time during the evolution. One of the approaches to t…
Scalar field as an intrinsic time measure in coupled dynamical matter-geometry systems. I. Neutral gravitational collapse
Anna Nakonieczna, Dong-han Yeom
There does not exist a notion of time which could be transferred straightforwardly from classical to quantum gravity. For this reason, a method of time quantification which would b…
Scalar field as a time variable during gravitational evolution
Anna Nakonieczna, Jerzy Lewandowski
Using a scalar field as an intrinsic 'clock' while investigating the dynamics of gravitational systems has been successfully pursued in various researches on the border between cla…
