NLS1 galaxies and estimation of their central black hole masses from the X-ray excess variance method
Marek Nikolajuk, Bozena Czerny, Pawel Gurynowicz
Black hole mass determination in active galaxies is a key issue in understanding various luminosity states. In the present paper we try to generalise the mass determination method…
All-sky search of NAUTILUS data
P. Astone, M. Bassan, P. Bonifazi +33
A search for periodic gravitational-wave signals from isolated neutron stars in the NAUTILUS detector data is presented. We have analyzed half a year of data over the frequency ban…
Decay of multiply charged vortices at nonzero temperatures
Tomasz Karpiuk, Miroslaw Brewczyk, Mariusz Gajda +1
We study the instability of multiply charged vortices in the presence of thermal atoms and find various scenarios of splitting of such vortices. The onset of the decay of a vortex…
Effective one body approach to the dynamics of two spinning black holes with next-to-leading order spin-orbit coupling
Thibault Damour, Piotr Jaranowski, Gerhard Schäfer
Using a recent, novel Hamiltonian formulation of the gravitational interaction of spinning binaries, we extend the Effective One Body (EOB) description of the dynamics of two spinn…
Splitting of doubly quantized vortices in dilute Bose-Einstein condensates
K. Gawryluk, T. Karpiuk, M. Brewczyk +1
We investigate the dynamics of doubly charged vortices generated in dilute Bose-Einstein condensates by using the topological phase imprinting technique. We find splitting times of…
Newton equation for canonical, Lie-algebraic and quadratic deformation of classical space
Marcin Daszkiewicz, Cezary J. Walczyk
The Newton equation describing the particle motion in constant external field force on canonical, Lie-algebraic and quadratic space-time is investigated. We show that for canonical…
