The Signature of Large Scale Structures on the Very High Energy Gamma-Ray Sky
A. Cuoco, S. Hannestad, T. Haugbølle +3
If the diffuse extragalactic gamma ray emission traces the large scale structures of the universe, peculiar anisotropy patterns are expected in the gamma ray sky. In particular, be…
Probing cosmological parameters with the CMB: Forecasts from full Monte Carlo simulations
Laurence Perotto, Julien Lesgourgues, Steen Hannestad +2
The Fisher matrix formalism has in recent times become the standard method for predicting the precision with which various cosmological parameters can be extracted from future data…
Measuring neutrino masses and dark energy with weak lensing tomography
Steen Hannestad, Huitzu Tu, Yvonne Y. Y. Wong
Surveys of weak gravitational lensing of distant galaxies will be one of the key cosmological probes in the future. We study the ability of such surveys to constrain neutrino masse…
Strongly Interacting Neutrinos as the Highest Energy Cosmic Rays: A Quantitative Analysis
Markus Ahlers, Andreas Ringwald, Huitzu Tu
Scattering processes in the cosmic microwave background limit the propagation of ultra high energy charged particles in our Universe. For extragalactic proton sources resonant phot…
Is it possible to tell the difference between fermionic and bosonic hot dark matter?
Steen Hannestad, Andreas Ringwald, Huitzu Tu +1
We study the difference between thermally produced fermionic and bosonic hot dark matter in detail. In the linear regime of structure formation, their distinct free-streaming behav…
Cosmic rays at ultra high energies (Neutrinos!)
Markus Ahlers, Andreas Ringwald, Huitzu Tu
Resonant photopion production with the cosmic microwave background predicts a suppression of extragalactic protons above the famous Greisen-Zatsepin-Kuzmin cutoff at about E_{GZK}…
