Astrophysical and Cosmological Neutrinos
— We review the role of massive neutrinos in astrophysics and cosmol-ogy, assuming that the oscillation interpretation of solar and atmospheric neutrinos is correct. In particular, we discuss cosmological mass limits, neutrino flavor oscillations in the early universe, leptogenesis, and neutrinos in core-collapse supernovae.
متن کاملStrongly Interacting Astrophysical Neutrinos∗
The origin and chemical composition of ultra high energy cosmic rays is still an open question in astroparticle physics. The observed large-scale isotropy and also direct composition measurements can be interpreted as an extragalactic proton dominance above the ankle at about 10 GeV. Photopion production of extragalactic protons in the cosmic microwave background predicts a cutoff at about 5 × ...
متن کاملHigh energy astrophysical neutrinos
High energy neutrinos with energy typically greater than tens of thousands of GeV may originate from several astrophysical sources. The sources may include, for instance, our galaxy, the active centers of nearby galaxies, as well as possibly the distant sites of gamma ray bursts. I briefly review some aspects of production and propagation as well as prospects for observations of these high ener...
متن کاملInto the 20th Century
At the beginning of the 20th century descendants of the early European settlers who first colonized the coasts of Virginia, the Carolinas, and Georgia were established throughout the region. Most all of the native people had been displaced. Cotton was king. The mature forests were being . the southern world, wavered and then toppled. Demand for the South’s cotton declined due to new competition...
متن کاملSterile Neutrinos in astrophysical and cosmological sauce
The study of sterile neutrinos has recently acquired a different flavor: being now excluded as the dominant solution for the solar or atmospheric conversions, sterile neutrinos, still attractive for many other reasons, have thus become even more elusive. The present relevant questions are: which subdominant role can they have? Where (and how) can they show up? Cosmology and supernovæ turn out t...
