Can extended bodies follow geodesic trajectories?
Georgios Lukes-Gerakopoulos, Sajal Mukherjee
We provide an extension of the analysis on whether an extended test body can follow a geodesic trajectory given by Mukherjee, S., Lukes-Gerakopoulos, G. and Nayak, R. K. (2022), Ex…
Growth of orbital resonances around a black hole surrounded by matter
Michal Stratený, Georgios Lukes-Gerakopoulos
This work studies the dynamics of geodesic motion within a curved spacetime around a Schwarzschild black hole, perturbed by a gravitational field of a far axisymmetric distribution…
Detectability of stochastic gravitational wave background from weakly hyperbolic encounters
Morteza Kerachian, Sajal Mukherjee, Georgios Lukes-Gerakopoulos +1
We compute the stochastic gravitational wave (GW) background generated by black hole-black hole (BH-BH) hyperbolic encounters with eccentricities close to one and compare them with…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Extended bodies with spin induced quadrupoles on circular equatorial orbits in Kerr spacetime
Iason Timogiannis, Georgios Lukes-Gerakopoulos, Theocharis A. Apostolatos
This work discusses the motion of extended test bodies as described by the Mathisson-Papapetrou-Dixon (MPD) equations in the pole-dipole-quadrupole approximation. We focus on the c…
Science with a small two-band UV-photometry mission I: Mission description and follow-up observations of stellar transients
N. Werner, J. Řípa, C. Thöne +33
This is the first in a collection of three papers introducing the science with an ultra-violet (UV) space telescope on an approximately 130~kg small satellite with a moderately fas…
Asymptotic gravitational-wave fluxes from a spinning test body on generic orbits around a Kerr black hole
Viktor Skoupý, Georgios Lukes-Gerakopoulos, Lisa V. Drummond +1
This work provides gravitational wave energy and angular momentum asymptotic fluxes from a spinning body moving on generic orbits in a Kerr spacetime up to linear in spin approxima…
Action-Angle formalism for extreme mass ratio inspirals in Kerr spacetime
Morteza Kerachian, Lukáš Polcar, Viktor Skoupý +2
We introduce an action-angle formalism for bounded geodesic motion in Kerr black hole spacetime using canonical perturbation theory. Namely, we employ a Lie series technique to pro…
