Golden Webinars – R. Brent Tully – "Galaxy Flows and the Formation of Large Scale Structure"



The ‘Golden Webinars in Astrophysics’ series seeks to bring forefront research in astronomy, astrophysics, and cosmology to the public in the English and Spanish language. Our speaker of the Golden Webinar on June 19th, 2020 was Brent Tully, who is Professor of Astronomy at the University of Hawaii.

Dr. Tully is working in the field of galaxy structure and near-field cosmology. He has pioneered the study of scaling relations of galaxies finding that their mass is related to their luminosity, a relation which today carries his name, the Tully-Fisher relation. With this technique he was able to derive the 3D locations of galaxies and show that they are distributed in a web-like structure. More recently he showed that the Laniakea supercluster of galaxies is home to the Milky Way based on the relative velocities of galaxies. In 2014, he received the Gruber Prize in Cosmology for his fundamental contributions.
