Abstract:
In April 2019, the EHTC (Event Horizon Telescope collaboration) released the first image of the M87 black hole shadow and this May, the black hole shadow image of our Milky Way galaxy was released. The EHTC has more than 300 members from different backgrounds and countries. I have been involved in this project as a data scientist for more than 8 years and collaborated with EHTC members to develop a new imaging method. The EHT is a huge VLBI (very long baseline interferometer), which is different from optical telescopes in that a lot of computation is required to obtain a single image. Black hole imaging is also very interesting from the data scientific viewpoint. In this talk, I will explain how the new imaging technique has been developed and the final images were created through our discussions.
