Identifying and Characterizing X- and Gamma-ray Counterparts of Gravitational Wave Sources with INTEGRAL and XMM

During the O2 LIGO/Virgo run, the first electromagnetic counterpart to a gravitational wave source was detected. For the on going LIGO/Virgo O4 science run, we propose a series of Target of Opportunity Observations to follow-up the GW alerts.





Details on Observing Strategy and Trigger Criteria
Our strategy is twofold: first we propose to quickly scan the GW error box with INTEGRAL in order to find the hard X-ray counterpart of GW alerts, secondly, we propose longer term observations of any X-ray detected counterpart (even if not discovered by INTEGRAL) with INTEGRAL and XMM.
