Spinning charged test particle dynamics around a Schwarzschild black hole embedded in a homogeneous magnetic field
Misbah Shahzadi, Martin Kolos, Ondrej Zelenka +1
We study the dynamics of spinning charged test particles orbiting a Schwarzschild black hole immersed in a test uniform magnetic field. This setup provides a simple but physically…
Combining Machine Learning with Recurrence Analysis for resonance detection
Ondřej Zelenka, Ondřej Kopáček, Georgios Lukes-Gerakopoulos
The width of a resonance in a nearly integrable system, i.e. in a non-integrable system where chaotic motion is still not prominent, can tell us how a perturbation parameter is dri…
Convolutional Neural Networks for signal detection in real LIGO data
Ondřej Zelenka, Bernd Brügmann, Frank Ohme
Searching the data of gravitational-wave detectors for signals from compact binary mergers is a computationally demanding task. Recently, machine learning algorithms have been prop…
MLGWSC-1: The first Machine Learning Gravitational-Wave Search Mock Data Challenge
Marlin B. Schäfer, Ondřej Zelenka, Alexander H. Nitz +20
We present the results of the first Machine Learning Gravitational-Wave Search Mock Data Challenge (MLGWSC-1). For this challenge, participating groups had to identify gravitationa…
Training Strategies for Deep Learning Gravitational-Wave Searches
Marlin B. Schäfer, Ondřej Zelenka, Alexander H. Nitz +2
Compact binary systems emit gravitational radiation which is potentially detectable by current Earth bound detectors. Extracting these signals from the instruments' background nois…
Growth of resonances and chaos for a spinning test particle in the Schwarzschild background
Ondřej Zelenka, Georgios Lukes-Gerakopoulos, Vojtěch Witzany +1
Inspirals of stellar mass compact objects into supermassive black holes are known as extreme mass ratio inspirals. In the simplest approximation, the motion of the compact object i…
