Dark Radiation and interacting scenarios
Roberta Diamanti, Elena Giusarma, Olga Mena +2
An extra dark radiation component can be present in the universe in the form of sterile neutrinos, axions or other very light degrees of freedom which may interact with the dark ma…
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…
Multi-wavelength Observations of the Enduring Type IIn Supernovae 2005ip and 2006jd
Maximilian Stritzinger, Francesco Taddia, Claes Fransson +19
We present an observational study of the Type IIn supernovae (SNe IIn) 2005ip and 2006jd. Broad-band UV, optical and near-IR photometry, and visual-wavelength spectroscopy of SN 20…
A Precision Photometric Comparison between SDSS-II and CSP Type Ia Supernova Data
J. Mosher, M. Sako, L. Corlies +10
Consistency between Carnegie Supernova Project (CSP) and SDSS-II supernova (SN) survey ugri measurements has been evaluated by comparing SDSS and CSP photometry for nine spectrosco…
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…
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…
