Collection of "Extended Abstracts" of talks presented at the SFB-375 workshop NEUTRINO ASTROPHYSICS, Ringberg Castle, Tegernsee, Germany, 20-24 Oct. 1997. Topics include Solar Neutrinos, Supernovae, Gamma-Ray Bursts, High-Energy Neutrinos (atmospheric, astrophysical), Cosmology, and Future Prospects. The focus is on astrophysical and experimental/observational aspects of astrophysical neutrinos while particle theory and neutrino laboratory experiments are not covered

The neutrino decits observed in four solar neutrino experiments, relative to the theoretical predictions, have led to fresh insights into neutrino and solar physics. Neutrino emission from distant, energetic astronomical systems may form the basis for a new eld of astronomy. Additional experiments are needed to test explanations of the solar neutrino decits and to allow the detection of more distant sources. Why neutrino astrophysics? Neutrino astrophysics has developed from theoretical calculations to an experimental discipline over the last three decades. As we shall see in later sections of this paper, solar neutrinos have been observed in four underground experiments and a burst of neutrinos was detected from a supernova in the Large Magellanic Cloud. The

An introduction to various topics in neutrino astrophysics is given for students with little prior exposure to this field. We explain neutrino production and propagation in stars, neutrino oscillations, and experimental searches for this effect. We also touch upon the cosmological role of neutrinos. A number of exercises is also included.

We review the role of massive neutrinos in astrophysics and cosmology, 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.

High-energy cosmic neutrinos carry unique information about the most energetic non-thermal sources in the Universe. This white paper describes the outstanding astrophysics questions that neutrino astronomy can address in the coming decade. A companion white paper discusses how the observation of cosmic neutrinos can address open questions in fundamental physics. Detailed measurements of the diffuse neutrino flux, measurements of neutrinos from point sources, and multi-messenger observations with neutrinos will enable the discovery and characterization of the most energetic sources in the Universe.

▪ High-energy (>100 MeV) neutrino astrophysics enters an era of opportunity and discovery as the sensitivity of detectors approaches astrophysically relevant flux levels. We review the major challenges for this emerging field, among which the nature of dark matter, the origin of cosmic rays, and the physics of extreme objects such as active galactic nuclei, gamma-ray bursts, pulsars, and supernova remnants are of prime importance. Variable sources at cosmological distances allow the probing of neutrino propagation properties over baselines up to about 20 orders of magnitude larger than those probed by terrestrial long-baseline experiments. We review the possible astrophysical sources of high-energy neutrinos, which also act as an irreducible background to searches for phenomena at the electroweak and grand-unified-theory symmetry-breaking scales related to possible supersymmetric dark matter and topological defects. Neutrino astronomy also has the potential to discover previous...

Neutrinos are very elusive particles. Having only weak (and gravitational) interactions they are extremely difficult to detect, but their study has been always extremely rewarding, both for physics and (more recently) astrophysics. In the last several years the progress in neutrino physics has been impressive leading to the discovery, for the first time, of physics of elementary particle phenomena beyond the Standard Theory. We have now a fair knowledge of the main features of neutrino mass-spectrum and mixing, which I’ll review in § 2. In § 3 I’ll describe the next-generation of experiments, which are under construction or concrete planning. While we know that neutrino masses are extremely small, when compared to the other elementary particles, we do not know their absolute values. This is a very difficult experimental problem, which must be attacked with complementary programmes: precision cosmology, beta-decay and double-beta decay experiments, as I’ll discuss in § 4 and § 5. Pho...

What do we mean by neutrino astronomy? Which information is it able to provide us and which is its potential? To address these questions, we discuss three among the most relevant sources of neutrinos: the Sun; the core collapse supernovae; the supernova remnants. For each of these astronomical objects, we describe the state of the art, we present the expectations and we outline the most actual problems from the point of view of neutrino astronomy.
