Role of dense matter in collective supernova neutrino transformations
A. Esteban-Pretel, A. Mirizzi, S. Pastor +4
For neutrinos streaming from a supernova (SN) core, dense matter suppresses self-induced flavor transformations if the electron density n_e significantly exceeds the neutrino densi…
Decoherence in supernova neutrino transformations suppressed by deleptonization
Andreu Esteban-Pretel, Sergio Pastor, Ricard Tomas +2
In the dense-neutrino region at 50-400 km above the neutrino sphere in a supernova, neutrino-neutrino interactions cause large flavor transformations. We study when the multi-angle…
Observational bounds on the cosmic radiation density
Jan Hamann, Steen Hannestad, Georg G. Raffelt +1
We consider the inference of the cosmic radiation density, traditionally parameterised as the effective number of neutrino species N_eff, from precision cosmological data. Paying p…
Signatures of axion-like particles in the spectra of TeV gamma-ray sources
Alessandro Mirizzi, Georg G. Raffelt, Pasquale D. Serpico
One interpretation of the unexplained signature observed in the PVLAS experiment invokes a new axion-like particle (ALP) with a two-photon vertex, allowing for photon-ALP oscillati…
Supernova neutrino observations: What can we learn?
Georg G. Raffelt
Twenty years after SN 1987A, the vast international programme of experimental neutrino physics and neutrino astronomy suggests that large detectors will operate for a long time. It…
Supernova Neutrino Opacities
Georg G. Raffelt
In a supernova (SN) core during infall and after collapse, neutrinos are trapped by their interactions with nucleons. For the axial-vector current interactions it is not enough to…
