Cosmological implications of neutrinos are reviewed. The following subjects are discussed
at a different level of scrutiny: cosmological limits on neutrino mass, neutrinos and primordial …

In the first part of this review we discuss the basic observational features at the end of the
cosmic ray (CR) energy spectrum. We also present there the main characteristics of each of …

We report on studies of the viability and sensitivity of the Askaryan Radio Array (ARA), a new
initiative to develop a Teraton-scale ultra-high energy neutrino detector in deep, radio …

The Antarctic Impulsive Transient Antenna (ANITA) completed its second Long Duration
Balloon flight in January 2009, with 31 days aloft (28.5 live days) over Antarctica. ANITA …

We present the first comprehensive discussion of constraints on the cosmic neutrino
background (CνB) overdensity, including theoretical, experimental and cosmological limits …

Assuming Majorana neutrinos, we infer from oscillation data the expected values of the
parameters mνe and mee probed by β and 0ν2β-decay experiments. If neutrinos have a …

We study the gravitational clustering of big bang relic neutrinos onto existing cold dark
matter (CDM) and baryonic structures within the flat ΛCDM model, using both numerical …

Applying our recently developed propagation code we review extragalactic neutrino fluxes
above 10 14 eV in various scenarios and how they are constrained by current data. We …

We report new limits on cosmic neutrino fluxes from the test flight of the Antarctic Impulsive
Transient Antenna (ANITA) experiment, which completed an 18.4 day flight of a prototype …

In this review we discuss the important progress made in recent years towards
understanding the experimental data on cosmic rays with energies≳ 1019 eV. We begin …
