Relativity of superluminal observers in spacetime
Andrzej Dragan, Kacper Dębski, Szymon Charzyński +2
We develop an extension of special relativity in dimensional spacetime to account for superluminal inertial observers and show that such an extension rules out the convention…
Trapping and guiding bodies by gravitational waves endowed with angular momentum
Iwo Bialynicki-Birula, Szymon Charzyński
Trapping of bodies by waves is extended from electromagnetism to gravity. It is shown that gravitational waves endowed with angular momentum may accumulate near its axis all kinds…
Black hole accretion in gamma ray bursts
Agnieszka Janiuk, Michal Bejger, Petra Sukova +1
We study the structure and evolution of the hyperaccreting disks and outflows in the gamma ray bursts central engines. The torus around a stellar mass black hole is composed of fre…
On the possible gamma-ray burst -- gravitational wave association in GW150914
Agnieszka Janiuk, Michal Bejger, Szymon Charzynski +1
Data from the Fermi Gamma-ray Burst Monitor satellite observatory suggested that the recently discovered gravitational wave source, a pair of two coalescing black holes, was relate…
Simulations of coalescing black holes
Agnieszka Janiuk, Szymon Charzynski
We describe the methods and results of numerical simulations of coalescing black holes. The simulation in dynamical spacetime covers the inspiral, merger, and ringdown phases. We a…
Accretion and outflow in the gamma ray bursts from black hole binary systems
Agnieszka Janiuk, Szymon Charzynski, Patryk Mioduszewski
We consider a scenario for the longest duration gamma ray bursts, resulting from the collapse of a massive star in a close binary system with a companion black hole. The primary bl…
