Current Lagrange Postdoctoral Fellows

#Eleonora Di Valentino

I obtained my PhD from the University of Rome 'La Sapienza' in January 2015 entitled 'Constraining Fundamental Physics with Current Cosmological Data' and I joined the Institut d'Astrophysique de Paris in November 2014 as a Lagrange post-doctoral fellow of the ILP LabEx. As CORE team member of the Planck Collaboration since 2013 in LFI and 2014 in HFI, I'm working on constraining cosmological parameters and on testing with simulations the high-ℓ Plik likelihood used to analyze the recent Planck 2015 data.

My research project is focused on cosmology, mainly on Cosmic Microwave Background anisotropies, and cosmological data analysis to constrain properties of the early and recent Universe and fundamental physics, as for example nuclear rates. A major goal of my research is to constrain neutrino physics (masses, isocurvature density perturbations, effective number) and other light fundamental particles such as axions (in the hot and cold dark matter scenarios) with cosmology, using different observables and methods that offer complementary informations.

Moreover, I'm investigating the principally tensions present between the different cosmological data and models, trying to understand if they can have a physical explanation, going beyond the standard LCDM cosmological model and, for example, testing modifications of gravity, or are simply due to systematic effects.
