معرفی
Sara Issaoun is an observational astronomer and NASA Einstein Fellow at the Harvard & Smithsonian Center for Astrophysics, where she also serves as a Systems Engineer for the Event Horizon Telescope (EHT) collaboration. Her research focuses on the collection, calibration, and imaging of millimeter-wave radio observations of supermassive black holes.
- PhD in Astrophysics from Radboud University (2021)
- MSc in Physics and Astronomy from Radboud University (2017)
- BSc in Physics from McGill University (2015)
Research Focus
Dr. Issaoun studies how supermassive black holes generate the highest energy processes in the Universe, ejecting jets of plasma that affect galaxy environments. She utilizes global networks of radio telescopes to image and study the immediate surroundings of supermassive black holes at the centers of our Galaxy and the galaxy M87. Her work aims to expand millimeter-wave radio imaging capabilities and forge connections between black hole shadow images and physics observed across the electromagnetic spectrum.
Publication Trends
Dr. Issaoun's recent work with the EHT collaboration demonstrates significant advances in black hole imaging, particularly in studying magnetic field structures around Sagittarius A*, long-term observations confirming the persistence of black hole shadows, and multi-wavelength analysis of gamma-ray outbursts from M87's powerful jet. Her research spans observational astronomy, theoretical physics, and advanced imaging techniques.
Awards
- NASA Einstein Fellowship
Collaborative Efforts
As a key member of the international EHT collaboration, Dr. Issaoun contributes to one of astronomy's most ambitious projects, which operates a virtual observatory using telescopes spanning from Greenland to the South Pole. Her work integrates data from the Center for Astrophysics' Submillimeter Array and Greenland Telescope with other global facilities.
