There's a lot of new information on the LIGO Website:
https://www.ligo.org/news.php (https://www.ligo.org/news.php)
which now includes a catalogue of black hole and neutron star mergers with computer simulations of each event. In particular there is a really good video covering GW170817 the neutron star merger and the science that was carried out:
