Invited Speakers

Plenary talks will be given by a international experts in relativistic astrophysics and cosmology.

Rennan Barkana

Tel Aviv University, Israel

Professor Rennan Barkana studies the formation and evolution of the first stars. He constructs models in order to predict the properties of the galaxies in which the first stars formed, and studies ways to probe them, especially via radio-wave radiation from hydrogen atoms at a wavelength of 21 cm. In 2018 Barkana showed that an observation of radio waves from the early Universe implies that the dark matter may have cooled the early cosmic gas. If confirmed by further measurements, this will be a milestone in physics, the first direct detection of the mysterious dark matter that makes up most of the matter in the Universe. After graduating Summa Cum Laude from the University of Pennsylvania with a B.A. in Physics and Math, Barkana got his Ph.D. in Physics at age 23 from MIT. Following a postdoctoral stint at the Institute for Advanced Study in Princeton plus a year in Canada, he assumed a faculty position at Tel Aviv University, Israel, where he is Professor and Head of the Department of Astrophysics. Barkana has been a Guggenheim Fellow, a Moore Distinguished Scholar at Caltech, and a Leverhulme Visiting Professor at Oxford.

Vincent Bourier

University of Geneva, Switzerland

Vincent Bourrier obtained in 2011 a Masters degree in Astrophysics, Space Sciences & Planetology (Paul Sabatier University), and an engineering degree in Space Sciences & Techniques (Institut Supérieur de l’Aéronautique et de l’Espace – SUPAERO). His doctoral research, carried out from 2011-2014 at the Institut d’Astrophysique de Paris, focused on the observation and modeling of atmospheric escape from exoplanets and the study of their orbital architectures, as a way to determine how exoplanets can come to orbit extremely close to their star and how they evolve in such extreme conditions. His work led to the detections of giant exospheres around Neptune-size exoplanets, and pioneered the measurement of orbital architectures around cool stars. Vincent Bourrier is now a Research and Teaching Fellow in the Department of Astronomy of the University of Geneva, where he combines his two research interests to understand the interplay between the atmospheric and orbital evolution of exoplanets.
