Origin of Delta N_eff as a Result of an Interaction between Dark Radiation and Dark Matter
Ole Eggers Bjaelde, Subinoy Das, Adam Moss
Results from the Wilkinson Microwave Anisotropy Probe (WMAP), Atacama Cosmology Telescope (ACT) and recently from the South Pole Telescope (SPT) have indicated the possible existen…
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.
Cosmology when living near the Great Attractor
Wessel Valkenburg, Ole Eggers Bjaelde
If we live in the vicinity of the hypothesized Great Attractor, the age of the universe as inferred from the local expansion rate can be off by three per cent. We study the effect…
Spherical collapse of dark energy with an arbitrary sound speed
Tobias Basse, Ole Eggers Bjaelde, Yvonne Y. Y. Wong
We consider a generic type of dark energy fluid, characterised by a constant equation of state parameter w and sound speed c_s, and investigate the impact of dark energy clustering…
Dark Matter Decaying into a Fermi Sea of Neutrinos
Ole Eggers Bjaelde, Subinoy Das
We study the possible decay of a coherently oscillating scalar field, interpreted as dark matter, into light fermions. Specifically, we consider a scalar field with sub-eV mass dec…
Are cosmological neutrinos free-streaming?
Anders Basboll, Ole Eggers Bjaelde, Steen Hannestad +1
Precision data from cosmology suggest neutrinos stream freely and hence interact very weakly around the epoch of recombination. We study this issue in a simple framework where neut…
