Sara Issaoun

Sara Issaoun is an NHFP Einstein Fellow at the Center for Astrophysics | Harvard & Smithsonian and a member of the Event Horizon Telescope collaboration. Her research centers around the collection, calibration, and imaging of millimeter-wave radio observations of supermassive black holes. Sara aims to expand millimeter-wave radio imaging capabilities and forge strong connections between the first images of supermassive black hole shadows and physics probed by partner facilities across the electromagnetic spectrum. Multi-wavelength constraints on black hole accretion flow properties will critically inform the scientific interpretation of images of black hole shadows, our understanding of jet-launching mechanisms, black hole spin measurements, and, ultimately, precision tests of General Relativity.
