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…
Probing the Nature of Black Holes: Deep in the mHz Gravitational-Wave Sky
Vishal Baibhav, Leor Barack, Emanuele Berti +26
Black holes are unique among astrophysical sources: they are the simplest macroscopic objects in the Universe, and they are extraordinary in terms of their ability to convert energ…
Factorization and resummation: A new paradigm to improve gravitational wave amplitudes. III: the spinning test-body terms
Alessandro Nagar, Francesco Messina, Chris Kavanagh +4
We present new calculations of the energy flux of a spinning test-body on circular orbits around a Schwarzschild black hole at linear order in the particle spin. We compute the mul…
Extended bodies moving on geodesic trajectories
Sajal Mukherjee, Georgios Lukes-Gerakopoulos, Rajesh Kumble Nayak
This work investigates whether an extended test body obeying the Mathisson-Papapetrou- Dixon equations under the Ohashi-Kyrian-Semerak spin supplementary condition can follow geode…
Classes of non-minimally coupled scalar fields in spatially curved FRW spacetimes
Morteza Kerachian, Giovanni Acquaviva, Georgios Lukes-Gerakopoulos
In this work we perform a dynamical analysis of a broad class of non-minimally coupled real scalar fields in the Friedmann-Robertson-Walker (FRW) spacetime framework. The first par…
Recurrence analysis of spinning particles in the Schwarzschild background
Ondřej Zelenka, Georgios Lukes-Gerakopoulos, Vojtěch Witzany
In this work the dynamics of a spinning particle moving in the Schwarzschild background is studied. In particular, the methods of Poincaré section and recurrence analysis are emplo…
