The Pierre Auger Collaboration
The Pierre Auger Collaboration has reported evidence for anisotropies in the arrival directions of cosmic rays with energies larger thanEth = 55 EeV. There is a correlation above the isotropicExpand
Properties and performance of the prototype instrument for the Pierre Auger Observatory
Abstract Construction of the first stage of the Pierre Auger Observatory has begun. The aim of the Observatory is to collect unprecedented information about cosmic rays above 10 18 eV . The firstExpand
Correlation of the highest energy cosmic rays with nearby extragalactic objects
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrate that there is a correlation between the arrival directions of cosmic rays with energy above {approx} 6 xExpand
The Stagger-grid: A grid of 3D stellar atmosphere models - I. Methods and general properties
Aims. We present the Stagger-grid, a comprehensive grid of time-dependent, three-dimensional (3D), hydrodynamic model atmospheres for late-type stars with realistic treatment of rad iative transfer,Expand
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest-energies, which are correlated with the positions ofExpand
The Pierre Auger Cosmic Ray Observatory
The Pierre Auger Observatory, located on a vast, high plain in western Argentina, is the world's largest cosmic ray observatory. The objectives of the Observatory are to probe the origin andExpand
Correlation of the highest-energy cosmic rays with nearby extragalactic objects.
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above 6 x 10(19) electron voltsExpand
The mass function of GX 339-4 from spectroscopic observations of its donor star
We obtained 16 VLT/X-shooter observations of GX 339-4 in quiescence in the period May - September 2016 and detected absorption lines from the donor star in its NIR spectrum. This allows us to measureExpand
Observation of the suppression of the flux of cosmic rays above 4 x 10 (19) eV.
TLDR
The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described and the hypothesis of a single power law is rejected with a significance greater than 6 standard deviations. Expand
THE TEMPERATURES OF RED SUPERGIANTS
We present a re-appraisal of the temperatures of red supergiants (RSGs) using their optical and near-infrared spectral energy distributions (SEDs). We have obtained data of a sample of RSGs in theExpand
