Discovered connection between active galactic nuclei and most energetic known cosmic rays

11-09-2007 · EurekAlert!

The prestigious journal Science has published this Nov. 9 the results of this research work, with members from 17 countries. The so-called Pierre Auger, with headquarters in Argentina and the participation of a research group of the Universidad de Granada, has proved that there is an anisotropy in the arrival directions of the most energetic particles ever detected, correlated with areas in which there are galaxies with active nuclei in the center.

Scientists discover a connection between active galactic nuclei and cosmic rays
12-19-2007 · EurekAlert!
'Science' has published the results of this research. The so-called Pierre Auger Collaboration, with headquarters in Argentina and participation from the UGR, has proved that there is an anisotropy in the arrival directions of the most energetic particles ever detected, correlated with areas in which there are galaxies with active nuclei in the centre. These conclusions have been obtained from the first data provided by the Pierre Auger Observatory of the Southern Hemisphere in Argentina.

Auger Observatory closes in on mystery, links highest-energy cosmic rays with violent black holes
11-08-2007 · EurekAlert!
The Pierre Auger Collaboration announced that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, the team of scientists found that the sources of the highest-energy particles are not distributed uniformly across the sky. Instead, the Auger results link the origins of these mysterious particles to the locations of nearby galaxies that have active nuclei in their centers.

Astronomers find first ever gamma ray clock
11-27-2006 · EurekAlert!
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays -- the most energetic such signal ever observed. Regular signals from space have been known since the 1960s, when the first radio pulsar (nicknamed Little Green Men-1 for its regular nature) was discovered. This is the first time a signal has been seen at such high energies -- 100,000 times higher than previously known.

A new mechanism for producing cosmic gamma rays from starlight is proposed
03-19-2007 · EurekAlert!
In 2002, when astronomers first detected cosmic gamma rays coming from the constellation Cygnus, they were surprised and perplexed. The region lacked the extreme electromagnetic fields that they thought were required to produce such energetic rays. But now a team of theoretical physicists propose a mechanism that can explain this mystery and may also help account for another type of cosmic ray, the high-energy nuclei that rain down on Earth in the billions.

New experiment to investigate the effect of galactic cosmic rays on clouds and climate
10-23-2006 · EurekAlert!
A novel experiment, known as CLOUD (Cosmics Leaving OUtdoor Droplets), begins taking its first data today with a prototype detector in a particle beam at CERN , the world's largest laboratory for particle physics. The goal of the experiment is to investigate the possible influence of galactic cosmic rays on Earth's clouds and climate. This represents the first time a high energy physics accelerator has been used for atmospheric and climate science.
