The hydrogen Lyman-alpha line is of utmost importance to many fields of astrophysics. This UV line being conveniently redshifted with distance to the visible and even near infrared wavelength ranges, it is observable from the ground, and provides the main observational window on the formation and evolution of high redshift galaxies. Absorbing systems that would otherwise go unnoticed are revealed through the Lyman-alpha forest, Lyman-limit, and damped Lyman-alpha systems, tracing the distribution of baryonic matter on large scales, and its chemical enrichment.
Dr. Hakim Atek is an assistant astronomer at Institut d'astrophysique de Paris (IAP) in France. He received his Master in astronomy and astrophysics from the University Pierre & Marie Curie (Paris VI). He obtained his Ph.D. in astrophysics in 2010 from the University Paris VI and the University of Geneva. He was a postdoctoral researcher at the California Institute of Technology (Caltech) for three years before moving to Switzerland for a second postdoctoral position at the Federal Institute of Technology in Lausanne (EPFL). During that period he spent one year as an associate research scientist at Yale University. He is primarily interested in the reionisation of the Universe and the formation and evolution of galaxies across cosmic time. He has a strong expertise in observational techniques with the Hubble Space Telescope and large ground-based facilities.
Prof. Sebastiano Cantalupo is an Assistant Professor of Cosmic Structure Formation at ETH Zurich. His research combines theoretical, numerical and observational approaches into a single program that is aimed at detecting and characterising with fluorescent Ly-alpha emission the diffuse intergalactic gas at high redshifts. This gas is believed to trace the cosmic web that drives the formation and growth of galaxies in the early Universe. Prof. Cantalupo completed his PhD in 2008 at ETH Zurich and subsequently held postdoctoral fellowship appointments at the Institute of Astronomy at the University of Cambridge and at the Department of Astronomy and Astrophysics at the University of California Santa Cruz. He returned to ETH in 2014 as Research Team Leader working on the exploitation of the MUSE Guaranteed Time of Observations. In 2016, Prof Cantalupo was awarded a Swiss National Science Foundation Professorship with associated research grant to build a new research group at ETH Zurich that combines theoretical and numerical models of Cosmological Structure Formation with the unprecedented data provided by the new MUSE integral field spectrograph.Il sito utilizza cookie ed altri strumenti di tracciamento che raccolgono informazioni dal dispositivo dell’utente.
