Measuring neutrino masses with a future galaxy survey
Jan Hamann, Steen Hannestad, Yvonne Y. Y. Wong
We perform a detailed forecast on how well a Euclid-like photometric galaxy and cosmic shear survey will be able to constrain the absolute neutrino mass scale. Adopting conservativ…
Confronting the sound speed of dark energy with future cluster surveys
Tobias Basse, Ole Eggers Bjaelde, Steen Hannestad +1
Future cluster surveys will observe galaxy clusters numbering in the hundred thousands. We consider this work how these surveys can be used to constrain dark energy parameters: in…
Light Sterile Neutrinos: A White Paper
K. N. Abazajian, M. A. Acero, S. K. Agarwalla +184
This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.
Thermalisation of light sterile neutrinos in the early universe
Steen Hannestad, Irene Tamborra, Thomas Tram
Recent cosmological data favour additional relativistic degrees of freedom beyond the three active neutrinos and photons, often referred to as 'dark' radiation. Light sterile neutr…
