Cosmic rays have been observed up to energies 108 times larger than those of the best particle accelerators. Studies of astrophysical particles (hadrons, neutrinos and photons) at their highest observed energies have implications for fundamental physics as well as astrophysics. Thus, the cosmic high energy frontier is the nexus to new particle physics. This overview discusses recent advances being made in the physics and astrophysics of cosmic rays and cosmic γ-rays at the highest observed… 
Neutrino Telescopes and High-Energy Cosmic Neutrinos
In this review paper, we present the main aspects of high-energy cosmic neutrino astrophysics. We begin by describing the generic expectations for cosmic neutrinos, including the effects of
Characterizing radio emission from extensive air showers with the SLAC-T510 experiment, with applications to ANITA
Neutrino and cosmic ray astronomy allow scientists to gather information about the highest energy processes in the universe. However, since cosmic rays are charged nuclei moving in astrophysical
Introduction to neutrino astronomy⋆
Abstract.This paper is an introduction to neutrino astronomy, addressed to astronomers and written by astroparticle physicists. While the focus is on achievements and goals of neutrino astronomy,
Prompt emission of high‐energy photons from gamma ray bursts
Within the internal shock scenario, we consider different mechanisms of high-energy ( > 1 MeV) photon production inside a gamma ray burst (GRB ) fireball and derive the expected high-energy photon
Neutrino detection with inclined air showers
The possibilities of detecting high-energy neutrinos through inclined showers produced in the atmosphere are addressed with an emphasis on the detection of air showers by arrays of particle
Modern Tests of Lorentz Invariance
This review summarizes both the theoretical frameworks for tests of Lorentz invariance and experimental advances that have made new high precision tests possible.
Astrophysical origins of ultrahigh energy cosmic rays
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 the


End to the cosmic ray spectrum
Observation of TeV gamma rays from the Crab Nebula using the atmospheric Cerenkov imaging technique
The Whipple Observatory 10 m reflector, operating as a 37 pixel camera, has been used to observe the Crab Nebula in TeV gamma rays. By selecting gamma-ray images based on their predicted properties,
Intergalactic Extinction of High Energy Gamma-Rays
High-energy tests of Lorentz invariance
We develop a perturbative framework with which to discuss departures from exact Lorentz invariance and explore their potentially observable ramifications. Tiny noninvariant terms introduced into the
Implications of the Lag-Luminosity Relationship for Unified Gamma-Ray Burst Paradigms
Spectral lags (τlag) are deduced using a cross-correlation methodology for 1429 long (T90 > 2 s) BATSE gamma-ray bursts (GRBs) with peak flux Fp > 0.25 photons cm-2 s-1, near to the BATSE trigger

Diffuse fluxes of cosmic high-energy neutrinos
Production spectra of high-energy neutrinos from galactic cosmic-ray interactions with interstellar gas and extragalactic ultrahigh-energy cosmic-ray interactions with microwave blackbody photons are
On the Generation of Ultra-High-Energy Cosmic Rays in Gamma-Ray Bursts: A Reappraisal
We reexamine critically the arguments raised against the theory that ultra-high-energy cosmic rays (UHECRs) observed at Earth are produced in gamma-ray bursts (GRBs). These include the limitations to
