- Imaging a Supermassive Black hole
August 5, 2022 (Fri) 19:00 – 20:30
Prof. Sheperd S. Doeleman
Harvard & Smithsonian
Dr. Sheperd S. Doeleman is the Founding Director of the Event Horizon Telescope (EHT), and an astrophysicist at the Center for Astrophysics | Harvard & Smithsonian (CfA), USA. By studying supermassive black holes, he pursues answers to several fundamental questions about the Universe: Do event horizons exist? Does Einstein's theory of gravity hold near a black hole? How do black holes affect the evolution of galaxies? Under his leadership, the EHT collaboration, consisting of more than 200 researchers around the world, successfully produced the first directly observed image of a black hole. This was made possible by linking together radio dishes across the globe to establish an Earth-size virtual telescope that achieved the highest angular resolution possible from the surface of our planet. He is now leading the next-generation EHT (ngEHT) project aimed at making the first movies of black holes. He received a B.A. from Reed College and a Ph.D. in astrophysics from MIT. He served as an assistant director of the MIT Haystack Observatory prior to joining the Harvard-Smithsonian Center for Astrophysics in 2012, where he is also co-director of the Black Hole Initiative at Harvard.

- The State of the Universe

Prof. Brian P. Schmidt
Australian National University
Prof. Brian Schmidt is Vice-Chancellor and President of the Australian National University (ANU), as well as a Professor at the Research School of Astronomy and Astrophysics at ANU. His research is focused on understanding the universe. He formed the High-z Supernova Search Team in 1994, aiming to determine the expansion rate of the universe using the most distant supernovae. Prof. Schmidt shared the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics along with Saul Perlmutter and Adam G. Riess for the discovery of the accelerating universe, consistent with the universe entering a dark energy dominated era roughly 4 billion years ago. He also studies gamma-ray bursts, which are the most energetic phenomena in the universe, and other stellar transients including supernovae of various types. Most recently, he co-lead the Southern Sky Survey team using the SkyMapper optical telescope located in northern New South Wales, Australia. The Southern Sky Survey aims to create a digital survey of the entire Southern sky. He received a B.A. in Physics and Astronomy from the University of Arizona and a Ph.D. in Astronomy from Harvard University.
