Time-slide correlation analysis of post-merger Extended Emission to GW170817

<p>Nico van Kampen Colloquium, ITP, Utrecht (October 23 2019,&nbsp;https://zenodo.org/record/3528005) - Movie clip.&nbsp;Shown is the result of $\chi$-image analysis of&nbsp;merged (H1,L1)-spectrograms produced in time-slide correlation analysis of H1-L1 data of GW170817.&nbsp;Time-sliding over -32s $\le&nbsp;\Delta t \le 32$s,&nbsp;including&nbsp;one-sample steps around the zero-crossing $\Delta t = 0$, reveals clustering of&nbsp;$\chi$-peak values&nbsp;representing a&nbsp;correlated&nbsp;(H1,L1)-detector response to a gravitational-wave signal.</p>
