Raul Jimenez, Ph.D., Professor of Theoretical Physics and Astrophysics, ICREA/University of Barcelona; Radcliffe Fellow, Radcliffe Institute for Advanced Study, Harvard University; Visiting Professor at the Harvard Institute for Theory and Computation, and the Institute for Applied Computational Science; and Royal Society Visiting Professor at the Imperial Center for Inference and Cosmology, Imperial College, London.
Raul Jimenez appeared on SftPublic's Contemporary Science Issues and Innovations January 26, 2016 to discuss Gamma Ray Bursts, the most energetic --and mysterious-- displays of energy in the universe. He also discusses (in this video) the continuing effort to understand dark energy.
Dr. Jimenez has been involved in the modeling of gamma ray bursts (GRBs). In the January 26 video he explains how he and his colleagues analyze the relationship between GRBs and life: areas of the universe where planets might be relatively safe --or not-- from the destructive force of GRB radiation.
Dr. Jimenez has made a number of major contributions in astrophysics: the first evidence of dark energy from the ages of high redshift galaxies and globular clusters, the origin of dark galaxies, the first evidence how galaxies are assembled as a function of cosmic time, the first determination of the expansion history of the Universe, the role of cosmic explosion in the survival of exo-life, the role of symmetries in the early universe and a theoretical lower bound to the value of the cosmological constant.
