Looking Back with Neutrinos
نویسنده
چکیده
We briefly discuss the history of suggestions for timeof-flight effects due to nonzero neutrino mass and a recent proposal that such effects can be used to determine the parameters of cosmology. With neutrinos there is potentially a much deeper “look back time” than with photons. We note a new point, that if future large scale neutrino detection arrays see long-time secular variations in counting rate, this could be due to highly redshifted bursts originating in the early universe.

Sterile Neutrinos in the Milky Way: Observational Constraints
We consider the possibility of constraining decaying dark matter by looking out through the Milky Way halo. Specifically we use Chandra blank sky observations to constrain the parameter space of sterile neutrinos. We find that a broad band in parameter space is still open, leaving the sterile neutrino as an excellent dark matter candidate. Subject headings: dark matter — elementary particles — ...
متن کاملSNEWS: A Neutrino Early Warning System for Galactic SN II
The detection of neutrinos from SN1987A confirmed the core-collapse nature of SN II, but the neutrinos were not noticed until after the optical discovery. The current generation of neutrino experiments are both much larger and actively looking for SN neutrinos in real time. Since neutrinos escape a new SN promptly while the first photons are not produced until the photospheric shock breakout ho...
متن کاملProspect for relic neutrino searches
Neutrinos from the Big Bang are theoretically expected to be the most abundant particles in the Universe after the photons of the Cosmic Microwave Background (CMB). Unlike the relic photons, relic neutrinos have not so far been observed. The Cosmic Neutrino Background (CνB) is the oldest relic from the Big Bang, produced a few seconds after the Bang itself. Due to their impact in cosmology, rel...
متن کاملUltra-High Energy Neutrinos: A Review of Theoretical and Phenomenological Issues
We review the phenomenology of UHE neutrino detection. The motivations for looking for such neutrinos, stemming from observational evidence and from the potential for new physics discoveries are enumerated, and their expected sources and fluxes are given. Cross-sections with nucleons at energies all the way upto 10 eV and the attenuation of fluxes in the Earth, both of which are physics issues ...
متن کاملNeutrino Mass: Where Do We Stand, and Where Are We Going? *
We discuss the three major hints of neutrino mass: the strong evidence of mass from the behavior of atmospheric neutrinos, the very promising further hint from the behavior of solar neutrinos, and the so-far unconfirmed hint from the LSND experiment. Then, we describe two illustrative neutrino-mass scenarios suggested by the observed hints. We identify the needed future tests of both the presen...
