Galaxies weigh in on neutrinos

Detection of neutrinos from supernovae in nearby galaxies.

While existing detectors would see a burst of many neutrinos from a Milky Way supernova, the supernova rate is only a few per century. As an alternative, we propose the detection of approximately 1 neutrino per supernova from galaxies within 10 Mpc, in which there were at least 9 core-collapse supernovae since 2002. With a future 1 Mton scale detector, this could be a faster method for measurin...

Are Diffuse High Energy Neutrinos from Starburst Galaxies Observable?

Loeb and Waxman have argued that high energy neutrinos from the decay of pions produced in interactions of cosmic rays with interstellar gas in starburst galaxies would be produced with a large enough flux to be observable. Their model is reexamined here and it is shown that the the neutrino flux from starburst galaxies, even given the various assumptions made by them, is more than an order of ...

Update on Atmospheric Neutrinos

We discuss the impact of recent experimental results on the determination of atmospheric neutrino oscillation parameters. We use all published results on atmospheric neutrinos, including the preliminary large statistics data of Super-Kamiokande. We re–analyze the data in terms of both νμ → ντ and νμ → νe channels using new improved calculations of the atmospheric neutrino flux. We compare the s...
