Many astrophysical phenomena are foreseen to emit GW transient signal with long duration (since few up to few hundreds seconds), such as fallback accretion, accretion disk instabilities, nonaxisymmetric deformations in magnetars. The theoretical predictions for those astrophysical processes cover a wide range of signal morphologies and in most cases are poorly known. In such cases, we need...
Gravitational waves, like light, could be gravitationally lensed by intervening matter. Recent studies suggest that we might see gravitational-wave lensing within the coming years as the current ground-based detectors are upgraded. However, the methods to detect and employ gravitational-wave lensing are entirely different from light lensing. Indeed, we detect waves instead of particles, and...
In this talk we present in-depth state-of-the-art parameter estimation studies of several gravitational wave events with open LIGO-Virgo data.
We use the fourth generation of phenomenological waveform models, the frequency domain IMRPhenomX and the time domain IMRPhenomT families which include higher harmonics and precession, and constitute the computationally most efficient...
