Julien Lesgourgues mostly deals with Astrophysics, Neutrino, Cosmic microwave background, Planck and Dark matter. His Astrophysics research is multidisciplinary, incorporating elements of Spectral line, Cosmic background radiation and Optics. His study in Neutrino is interdisciplinary in nature, drawing from both Cosmology, Cold dark matter and Lambda-CDM model.
Julien Lesgourgues combines subjects such as COSMIC cancer database, Inflation, Inflaton and Reionization with his study of Cosmic microwave background. Julien Lesgourgues focuses mostly in the field of Planck, narrowing it down to topics relating to Redshift and, in certain cases, Residual. His Dark matter research incorporates themes from Warm dark matter, Statistical physics, Phase space and Sterile neutrino.
His main research concerns Astrophysics, Cosmic microwave background, Planck, Neutrino and Dark matter. Redshift, Galaxy, Cosmology, Dark energy and Universe are the primary areas of interest in his Astrophysics study. Julien Lesgourgues studies Cosmic background radiation, a branch of Cosmic microwave background.
