Cosmic-ray volleys from the Galactic Center and their recent impact on the earth environment

(March 1987)

7. Conclusions

The folowing conclusions are proposed:

1) Periodically the center of our galaxy enters an explsive phase during which it generates an outburst of cosmic rays in the form of highly relativistic electrons and positrons with total particle energies of 10 to the power of 57 ergs or more.
2) These outburst last anywhere from several hundred to several thousand years, major events recurring about once every 5000-15000 years.
