Gravitational waves from oscillating accretion tori: Comparison between different approaches
Alessandro Nagar, Jose A. Font, Olindo Zanotti +1
Quasi-periodic oscillations of high density thick accretion disks orbiting a Schwarzschild black hole have been recently addressed as interesting sources of gravitational waves. Th…
Gauge-invariant Non-spherical Metric Perturbations of Schwarzschild Black-Hole Spacetimes
Alessandro Nagar, Luciano Rezzolla
The theory of gauge-invariant non-spherical metric perturbations of Schwarzschild black hole spacetimes is now well established. Yet, as different notations and conventions have be…
On the time delay in binary systems
Angelo Tartaglia, Matteo Luca Ruggiero, Alessandro Nagar
The aim of this paper is to study the time delay on electromagnetic signals propagating across a binary stellar system. We focus on the antisymmetric gravitomagnetic contribution d…
