Jet Gravitational Waves (2210.02740v1)

Abstract: The acceleration of a jet to relativistic velocities produces a unique memory type gravitational waves (GW) signal: {\it Jet-GW}. I discuss here resent result concerning properties of these GWs and consider their detectability in current and proposed detectors. Classical sources are long and short Gamma-ray bursts as well as hidden jets in core-collapse supernovae. Detection of jet-GWs from these sources will require detectors, such as the proposed BBO, DECIGO and lunar based detectors, that will operate in the deciHz band. The current LVK detectors could detect jet-GWs from a Galactic SGR flare if it is sufficiently asymmetric. Once detected these signals could reveal information concerning jet acceleration and collimation that cannot be explored otherwise.
