Combined XMM-Newton and Chandra observations of the X-ray light curve plateau in GW170817
Abstract
We report previously-unpublished Director's Discretionary Time XMM-Newton observations of neutron star merger GW170817 (PI: Schartel). This XMM-Newton observation at 162 days post-merger confirms previous Chandra observations of a plateau in the X-ray light curve of GW170817's non-thermal synchrotron afterglow, before its current fading (e.g., Nynka et al., 2018, Alexander et al. 2018).
