Description
Magnetar flares are thought to be associated with gravitational waves (GWs) through different emission processes. In the past, several searches for both short and long duration GW signals from magnetar flares have been performed by the LIGO-Virgo-KAGRA (LVK) collaboration, but no detection has been reported so far. In order to increase the chance of detecting such weak GW signals, higher sensitivity is needed.
The Einstein Telescope (ET), a third generation GW detector currently in the planning stage, will be at least one order of magnitude more sensitive than second generation GW detectors: thanks to this, it will possibly be able to detect GWs associated with galactic magnetar flares, allowing us to probe the rich physics associated with magnetars. .
In this talk we present the prospects for detecting GWs from magnetar flares with ET using a targeted, unmodeled search; specifically, we adopt the software “X-pipeline”, currently used within the LVK collaboration, to explore the capability of ET to detect GW signals expected to be produced under different physical mechanisms.
