TITLE: Gravitational wave and electromagnetic signatures of binary black holes with circumbinary gas ABSTRACT: Binary black holes (BHBs) embedded in dense gas hold the promise of so-called "multi-messenger astrophysics": when they are detected both through gravitational waves (GWs) and electromagnetic (EM) observations, they will enable novel science.  This is true both for massive BHBs, whose … Continue reading "CRA Seminar: Zoltan Haiman (Columbia, on sabbatical at GT)"
