A New Model of the Galactic Magnetic Field
A new, much-improved model of the Galactic magnetic field (GMF) is presented. We use the WMAP7 Galactic synchrotron emission map and more than 40,000 extragalactic rotation measures to constrain the
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 isotropic
The 2dF Galaxy Redshift Survey: Luminosity functions by density environment and galaxy type
We use the 2dF Galaxy Redshift Survey to measure the dependence of the bJ-band galaxy luminosity function on large-scale environment, defined by density contrast in spheres of radius 8h-1 Mpc, and on
The speed of the ‘bullet’ in the merging galaxy cluster 1E0657−56
Deep Chandra exposures of the hot galaxy cluster 1E0657-56 have revealed a highly dynamical state of the system due to an ongoing merger with a massive subcluster. The system is observed shortly
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 x
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 volts
Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 × 1018 eV
TLDR
The Pierre Auger Collaboration reports the observation of thousands of cosmic rays with ultrahigh energies of several exa–electron volts, arriving in a slightly dipolar distribution, showing that they originate outside the Milky Way Galaxy.
