GBH Forum Network | Our Expanding Universe: The DESI Project's First Results @GBHForumNetwork | Uploaded May 2024 | Updated October 2024, 1 day ago.
Understanding the accelerating expansion of our universe is one of the most important goals of modern astronomy. And it is a huge technical challenge. Paul Martini, with an international team of almost 500 researchers, built the unique telescope, the Dark Energy Spectroscopic Instrument (DESI), that captures (via spectrographs) light from galaxies and supermassive black holes (quasars) 11 billion light-years away. The first results are amazing, and provide the best explanation of dark energy and cosmic expansion that is currently possible. Dr. Martini describes the DESI project, its scientific significance, and the very exciting results so far.
Dr. Martini's research focus is observational cosmology and the formation and evolution of galaxies and supermassive black holes. He has served as Instrument Scientist in the design and testing of DESI. He is a rare scientist able to combine engineering and research skills.
