The Hubble Constant Tension

Eleonora Di Valentino is Royal Society Dorothy Hodgkin Research Fellow at the University of Sheffield. She received her Ph.D. in Theoretical Physics with a thesis in Cosmology from the University of Rome La Sapienza. She joined the Institute d'Astrophysique de Paris in Paris as Lagrange Fellow and contributed to the Planck team's work on the legacy release. She relocated to the University of Manchester in the UK with Postdoctoral Researcher position and contributed to the Dark Energy Survey collaboration. She became Addison-Wheeler Fellow at the Institute of Advanced Studies of Durham University. Her current project is focused on addressing cosmological tensions, particularly seeking theoretical solutions to the Hubble constant tension.   Dillon Brout is Assistant Professor at Boston University in the Departments of Astronomy and Physics. He received his Ph.D. in Physics and Astronomy from the University of Pennsylvania. He obtained a NASA Einstein Fellowship which he took to the Smithsonian Astrophysical Observatory and which was followed on by a postdoctoral research position at Harvard University. He has led numerous Type Ia supernova cosmology analyses which include Pantheon+, The Dark Energy Survey, and he now co-leads both the Dark Energy Spectroscopic Instrument and the Legacy Survey of Space and Time Dark Energy Science Collaboration Time Domain Working Groups. His current effort is focused on building and analyzing ever larger samples of supernovae to measure cosmic structure and expansion history.
